Crash Course into Remix & Storyblok

In this workshop, first, we’ll go over the different ways you can consume APIs in React. Then, we’ll test each one by fetching content from a headless CMS (with both REST and GraphQL) and checking in detail how they work.
While there is no advanced React knowledge required, this is going to be a hands-on session, so you’ll need to clone a preconfigured GitHub repository and utilize your preferred React programming editor, like VS Code.
You will learn:- What diverse data fetching options there are in React- What are advantages and disadvantages of each- What are the typical use cases and when each strategy is more beneficial than others

Join us for a hands-on workshop where we'll show you how to level up your React skills to build a high-performance headless website using Next.js, Sanity, and the JAMstack architecture. No prior knowledge of Next.js or Sanity is required, making this workshop ideal for anyone familiar with React who wants to learn more about building dynamic, responsive websites.
In this workshop, we'll explore how Next.js, a React-based framework, can be used to build a static website with server-side rendering and dynamic routing. You'll learn how to use Sanity as a headless CMS to manage your website’s content, create custom page templates with Next.js, use APIs to integrate with the CMS, and deploy your website to production with Vercel.

By the end of this workshop, you will have a solid understanding of how Next.js and Sanity.io can be used together to create a high-performance, scalable, and flexible website.

Headless architecture has gained immense popularity in recent years for its ability to decouple the frontend and backend, empowering developers to create engaging, interactive, and scalable web applications. 
In this workshop, we will quickly take a dive into the Headless World and Architecture. 
Additionally, we will build a blog website super quickly using Storyblok, a headless CMS that offers a real-time preview feature with nestable component approach, and Astro (3.0) which is already creating a buzz with the new app directory. 
- Master headless CMS fundamentals- Master an Astro & headless CMS approach- Use Atomic design in your Astro & Storyblok application- Creating pages, adding content and understanding how the dynamic routing works with headless

During this crash course, we’ll create a new project in the headless CMS, create the content model and data using the Kontent.ai CLI. Then, we’ll use the content to build an Astro website including front-end components and rich text resolution using Portable Text.
This will be hands-on workshop, you’ll need VS Code, Git, NPM and basic knowledge of JavaScript. Don’t worry, I will explain all the steps as we advance through the workshop and you will be able to directly ask any questions.

Localized content helps you connect with your audience in their preferred language. It not only helps you grow your business but helps your audience understand your offerings better. In this workshop, you will get an introduction to localization and will learn how to implement localization to your Contentful-powered Remix website.

Node.js has become an increasingly popular language to build and deploy backend APIs. In a world of legacy CMSs adopting decoupled implementations, plenty of frameworks have sprung up to classify themselves as "headless" CMSs, designed from the start to provide an easy way to personalize content models, administer permissions and authentication, and serve a content API quickly.
Strapi, one of the leaders in this space, has recently released their v4 version of the framework, and with Platform.sh it can be deployed alongside a number of frontends within the same project, giving a drastically simplified development experience working with decoupled sites. In this workshop, we'll deploy a Strapi demo application, which has been configured to serve a restaurant review site.
Piece piece you will add database services, tests, and frontends, all within the safety of isolated development environments. At the end, each user will have a functioning decoupled site, and some greater understanding of working with decoupled sites in production.

TL;DR: CMS Migration NumbersMost website migrations fail the same way: rankings drop, traffic disappears, and recovery takes months. Teams that avoid migration-related issues do not rely on luck; they approach CMS migration as an ongoing engineering discipline rather than a one-time technical task. The long-term success of a migration is whether it drives sustained growth or leads to performance decline months after launch—largely depends on how early SEO strategy is integrated into the process.The headless CMS market reached $816M in 2024 and is growing 22% annually, with 73% of enterprises already adopting headless architecture. As more companies move to API-first stacks, choosing the right CMS migration service is critical to:Preserve search rankings with proper redirects and URL mappingImprove website performance and Core Web VitalsEnable faster content workflows with headless CMSReduce long-term CMS costs and vendor lock-inThis guide reviews the best CMS migration service providers in 2026 to help you migrate safely — without traffic loss or technical debt.Migrate a Website-Growing TrendMost analysts expect the majority of digital teams to move away from traditional, page-based CMS platforms toward composable, API-first stacks over the next 2-3 years. The reason is simple: as brands expand across more channels, markets, and campaigns, traditional CMS workflows break down. Content gets duplicated across sites, templates become hard to change, and even small experiments require a developer.Headless CMS solves this by keeping content in one structured hub that feeds every channel through APIs, so editors can publish updates without waiting on the dev team. But a CMS to CMS migration is more than a technical switch. Those teams that dive into a website migration service without a clear SEO strategy risk losing the very signals search engines use to trust and rank their site. That's why this kind of transition works best with a CMS agency that treats SEO as part of the migration plan, not an afterthought.What Is Headless CMS Migration? Migrating a website to a headless CMS means decoupling your content from how it's presented. s work in one central content hub. Developers build fast, flexible frontends in Next.js, React, or whatever the delivery layer demands for any channel: web, app, or in-product UI. The content model stays stable. The presentation layer becomes a technical decision, not a CMS constraint.That separation is the point. It's also where migrations get complicated.Your SEO won't migrate automatically. Rankings follow decisions — specifically, the ones you make before anything moves. Keep URLs as stable as possible. Build a complete 301 redirect map for every URL that changes. Crawl both the old and new versions of the site before launch to catch missing metadata, lost content, broken internal links, and orphaned pages. That decision compounds: a redirect missed at migration can take months to recover from in search.The architecture is the easy part to get excited about. The unglamorous audit work is what protects everything you've already earned.Why Go Headless? CMS Migration JustificationWhat pushes businesses to CMS migration besides the draconian price of your Contentful? Let me guess, the code quality? Security reasons? It depends.That's exactly what professional headless CMS migration services are designed to solve — handling the technical and SEO complexity so your team doesn't have to.Here are the top 9 reasons businesses seek headless CMS migration services, starting with economic ones and followed by technical website reasons:Escape runaway license costs: Legacy and monolithic CMS platforms keep increasing base subscription fees. Ballooning costs, driven by user-seat pricing and add-on charges, are turning your content stack into a fixed cost that grows faster than your traffic or revenue. This erodes ROI over time and makes staying on your current CMS increasingly hard to justifyStop paying for “empty” overages: Many enterprise CMS contracts charge extra for API calls, environments, locales, or storage, even if you’re not using advanced features that justify the billReplace complex pricing with predictable value: Moving to a modern headless stack lets you choose components (CMS, hosting, search, media) that match your actual usage and budget, instead of being locked into one vendor’s bundled pricingReinvest license spend into growth: The money currently tied up in inflated CMS subscriptions can be redirected into content production, SEO, and experimentation that measurably drives revenue.”Future‑proof against price hikes: A composable headless architecture gives you leverage; if one vendor’s pricing becomes unreasonable, you can swap it out without rebuilding your entire siteSecurity vulnerabilities: Traditional monolithic CMS platforms like WordPress (when unmanaged) or aging proprietary systems are prime targets for hackers. Outdated plugins, unpatched cores, and shared databases create attack surfaces that headless, API-first architectures simply don't havePoor performance: A slow website is a leaking revenue pipe. If your CMS is tightly coupled to your frontend, every design tweak becomes a developer ticket. Businesses migrate to gain speed, better Core Web Vitals scores, and the freedom to optimize independentlyTechnical debt: Years of patched plugins, custom workarounds, and legacy integrations quietly accumulate until your codebase becomes a house of cards. A full site migration is often the cleanest escape routeLack of scalability: When your CMS can't handle traffic spikes, multiple languages, or omnichannel delivery without expensive custom work, growth itself becomes the enemy. Modern headless platforms are built to scale without breakingThe Moment Teams Start Looking for a Website Migration AgencyMost teams don't reach out to website migration companies because the technology stopped working. They migrate because the cost of staying finally outweighed the cost of moving. The CMS that made sense three years ago — reasonable at the time, familiar to the team, integrated into the workflow — quietly becomes the thing that slows every campaign, blocks every experiment, and shows up as a line item that's hard to justify at budget review.The shift is rarely dramatic. It's the accumulation of small frictions: a developer ticket for a content change that should take thirty seconds, a performance audit that points back to the platform, a pricing renewal that arrives with a number that no longer matches the value. At some point the question changes from "should we migrate?" to "what were we waiting for?"That's when the search for website migration companies begins — not in crisis, but past the point where staying is the safer option.The world of content systems has changed, just like you after Covid. While platforms like Storyblok are popular among marketers for visual editing, the best CMS depends on your team structure, developer resources, and content complexity. Alternatives like Contentful, Sanity, and Strapi may be better suited depending on the use case. We advise Storyblok for its simplicity, as it's the CMS that consistently gets the least pushback from the people who actually use it daily.

How do you move a site without significant SEO loss, and who can assist my team with CMS migration services?What should be taken into account before CMS migration?One of the most critical decisions, besides choosing website migration company, is choosing the right CMS, and for most businesses today, that means going headless. But raw headless power alone isn't enough; consider the following:CMS Flexibility: When you migrate a website, whether from a legacy platform or decide to migrate a WordPress website to a more scalable architecture, clients increasingly demand a CMS that supports diverse, flexible layouts for individual content types. Think distinct page structures for blog posts, case studies, landing pages, and product pages, all managed from a single platform without duplicating effort.Friendliness: The days of requiring a developer to publish a paragraph or rearrange a section are over. The best modern CMS platforms integrate a visual page builder directly into the interface, empowering marketing and content teams to construct, update, and iterate on pages entirely independently — a capability that WordPress alone, in its traditional form, often struggles to deliver at scale.SEO Preservation: A poorly executed migration can wipe out years of hard-earned organic rankings overnight. Careful URL mapping, redirect management, and metadata migration are just as important as the technical build itself — and should never be an afterthought.Localisation Support: For any business operating across borders, localization is no longer a nice-to-have. The ability to manage multiple languages, regional content variations, and locale-specific SEO from within the same CMS is now a baseline expectation, not a premium feature.Get these four right, and your website migration becomes a launchpad; get them wrong, and it becomes a liability.SEO Preservation: The Part That's Easy to Get WrongWebsite migration impacts SEO reasonably. Every page you've ranked took time. Every backlink pointing at a specific URL is a signal you've earned. When you migrate a website, that equity doesn't transfer automatically; it follows the decisions you make before a single line of code changes.The analogy is here: fixing SEO after a website migration is like correcting old handpoke tattoos done by an amateur. You can do it, but you're always working against what's already there. The cleaner move is to plan and protect everything upfront.That means treating SEO preservation as an engineering problem, not an afterthought.Before any migration begins, a serious team runs a full technical audit: title tags, meta descriptions, headings, and image alt text – and documents every URL in the existing site. Not most of them. Every single one. From there, a complete 301 redirect map is built, mapping each old URL to its new destination. Nothing gets left to assumptions.CMS Migration ChecklistThe pre-migration checklist that compounds into your post-launch performance:Full technical audit of the existing siteComplete URL inventory301 redirect map (old URL → new URL)Analytics baseline exportInternal linking structure documentationCurrent ranking data exportSchema markup documentationFull site backup before anything movesMiss one of these, and you're not migrating a website (CMS); you're rebuilding your search visibility from scratch. The development agencies that get this right treat the checklist above as the floor, not the ceiling.
The post-launch CMS migration checklist:Organic traffic monitoring via GA4 and Google Search Console from day one. Ahrefs if you want a second signal.Crawl error checks in the first 48 hours — redirect failures and orphaned pages surface fast if you're watching.Ranking position tracking — flag significant drops in the first two weeks. The faster you catch them, the less they compound.Metadata review in the first month — rewrite underperforming title tags and descriptions while the index is still settling.Index coverage report — confirm priority pages are being crawled and indexed correctly.This combo of technical care and content parity lets you migrate a website to a headless content management system for performance without sacrificing your past merits.Replatforming vs. Migration. Why ''just replatforming' is Not Enough“Just replatforming” is not enough because it moves your site to new tech without accurately fixing the underlying problems in content, workflows, data, and SEO. If you simply swap CMS platforms or hosting and keep the same messy content model, fragmented data, and ad‑hoc processes, you end up with the same bottlenecks. The difference is that only now they’re running on a newer, more expensive stack. A meaningful website migration is an opportunity to rethink information architecture, streamline content types and workflows, clean and normalise data, and plan SEO and analytics from the start so your team actually ships faster and your site performs better instead of “lifting and shifting” old issues into a shiny new interface.How Long Does it Take to Migrate a Website?Migrating a website is rarely a one-size-fits-all process. Migration timelines vary widely depending on the size, complexity, and condition of your existing setup. A simple CMS migration for a small site might take as little as two to four weeks, while a full global website migration involving thousands of pages, multiple languages, and complex integrations can take anywhere from three to six months. Headless CMS Migration Process and PlanningWhen you move a website from a legacy platform to a headless CMS solution, the bulk of the time goes into content mapping, URL redirects, SEO preservation, and quality assurance, not just the technical build. For instance, WordPress migrations tend to be faster thanks to a mature ecosystem of tools, but enterprise-scale projects demand far more planning. Working with a professional CMS migration service can really make a difference. Website migration team have established workflows that help lower risks, safuguard your search rankings, and minimize downtime. No matter if you need basic website migration services for a small business or a complicated content overhaul across different region for enterprise business, the key principle remains unchanged:The more thorough your plan for a migration, the smoother it will be.Top 11 Website CMS Migration Services to Future-Proof Your WebsiteHere's a list of headless CMS migration services that cater to different business needs, covering everything from consulting and maintenance to migrating custom features and integrating AI.1.

The language signals ambition but not specificity. How to Choose the Right CMS Migration ServicesNot every agency that calls itself a CMS migration partner/provider is built for the same problem. Before you shortlist anyone, check these five things:Technical stack expertise: do they know the platform you're moving to, or are they learning on your project?E-commerce experience: product data, payments, and checkout flows don't survive a careless lift-and-shiftCMS specialists vs. generic dev shops: specialists know what breaks, what compounds, and what to protectSEO-safe methodology: redirects, canonicals, ranking preservation — this should be a defined process, not improvised per projectPost-launch support: what happens at week three when something misfires? The answer tells you more than the proposal doesHeadless CMS Agencies QuickpickThis list is very general, as there is no single winner or 'best' CMS service/agency across all scenarious. Everything depends on your site architecture, team structure, and risks around SEO. With that in mind, choose:

CMS Migration Service FAQWhat happens when you migrate a website?When you run a website migration, you move key elements like domain, CMS platform, URL structure, design, and content from one setup to another. If it’s not planned properly, this can temporarily affect organic traffic, rankings, and tracking while search engines discover and re‑evaluate your new pages.Is SEO migration necessary?Yes, SEO‑led website migration services are essential if you want to keep your existing visibility, rankings, and revenue. Without structured SEO migration work (redirect mapping, content parity, technical checks), you risk broken URLs, lost authority, indexation issues, and significant drops in traffic.Can I migrate from WordPress to a headless CMS without traffic loss? You can migrate a WordPress website to a headless CMS with minimal or no lasting traffic loss if you treat it as a full SEO website migration project. That means preserving high‑value URLs where possible, implementing page‑level 301 redirects, maintaining or improving content, and launching on a fast, SEO‑friendly front end.Do I need e-commerce CMS migration services for Shopify/BigCommerce?If you are moving an e-commerce shopfront on Shopify or BigCommerce to a headless architecture, we recommend e-commerce CMS migration services.

Its visual page builder lets non-technical teams build and publish pages without a developer in the loop.

The best headless CMS agency or headless web development partner for your project is the one that recommends the right platform for your context — not the one they are most comfortable with. This guide ranks agencies on verifiable CMS expertise, platform breadth, migration track record, and documented editorial outcomes.TL;DRA genuine headless CMS agency recommends the right platform for each client context; multi-platform production experience and content modeling depth are the two criteria that separate specialists from frontend shops that happen to use a CMSPlatform partnership tiers and listing platform rankings are commercially influenced signals — verified review content describing specific editorial and business outcomes is more reliableKey selection criteria: verified production cases across at least three CMS platforms; content modeling treated as a core deliverable not a configuration task; evidence the agency has recommended against their preferred platform for a specific client; testimonials from editorial stakeholders, not only technical leadsFocusReactive ranks first: six CMS platforms in production, official partnerships on four, vendor-agnostic selection verified across case studiesMid-complexity implementations typically start at $30,000; migrations with content modeling redesign run $50,000–$150,000; enterprise multi-market builds start at $150,000Top 4 headless CMS agencies in 2026FocusReactive — the most platform-complete headless CMS agency on this list; official partners of Sanity, Storyblok, Contentful, and Payload CMS; production experience on Directus and DatoCMS; genuine vendor-agnostic selection process with a proprietary CMS toolkit refined across dozens of deploymentsAnything Agency — 10+ years headless-only delivery; Storyblok UK & Ireland Partner of the Year; Contentful certified; deep editorial case studies including long-term enterprise partnershipsBits Orchestra — .NET and CMS specialist with Kentico Xperience Bronze Partner status plus Contentful, Strapi, Sanity, and Umbraco; strongest for enterprise portal modernisation and B2B organisations in the Microsoft ecosystemThe Frontend Company — frontend-led headless CMS integration with a documented multi-platform practice across Contentful, Sanity, Strapi, and DirectusIntroStructured content has quietly become the foundation of two of the most consequential shifts in digital right now: editorial teams that can publish, localise, and iterate without raising a developer ticket, and content that surfaces in AI-generated answers rather than only in traditional search rankings. Both outcomes depend less on which headless CMS you choose and more on how deeply the agency implementing it understands content modeling, governance, and the relationship between content structure and machine readability.The headless CMS software market reached approximately $820 million to $1.3 billion in 2024, expanding to an estimated $970 million to $1.5 billion in 2025, according to Future Market Insights. This represents two to three times the growth rate of the overall CMS market. Headless CMS market size 2025: The global headless CMS market reached an estimated $970M–$1.5B in 2025, growing at 2–3× the rate of the broader CMS market (Future Market Insights).The broader global CMS market stands at approximately $31–35 billion in 2025, according to Mordor Intelligence and Grand View Research, growing at a 7.7–10.6% CAGR through the early 2030s. Within that total, the headless segment is far smaller but far faster-growing.This shift has structural drivers. Gartner requires composability as a mandatory criterion for inclusion in its Magic Quadrant for Digital Experience Platforms, and projects that 70% of organisations will be mandated to acquire composable DXP technology by 2026, up from 50% in 2023. What was a developer preference three years ago has become enterprise infrastructure policy.That change raises the bar for what agencies need to deliver. A team with experience on one headless CMS is not the same as an agency that has selected, migrated to, and governed five different headless platforms across varied client contexts. As the market matures, that distance grows.What makes a legitimate headless CMS agencyMost comparable lists rank each headless CMS development company by Clutch position or platform partner directory placement. Both signals are compromised: Clutch and DesignRush offer paid tier upgrades that influence placement without transparent disclosure, and platform partner status can be acquired for business development purposes rather than reflecting deployment volume or client outcomes. We used review platforms as sources of verified feedback content only — not as ranking inputs.The criteria below are harder to fake and more predictive of outcomes.Multi-platform portfolio (highest weight)A genuine headless CMS agency has delivered real client work across at least three distinct platforms — for example, Contentful, Storyblok, Sanity, Payload, Directus, Hygraph, or Prismic. Agencies that default every client to a single platform are not making advisory recommendations; they are extending their own technical familiarity at the client's expense. Different client contexts require different platforms: a marketing team that needs visual editing independence is poorly served by Sanity's developer-centric studio; an enterprise managing structured content across 20 locales is poorly served by a self-hosted Strapi instance without the infrastructure to support it.Verified client outcomes — reviews and casesWe focused on verified reviews that describe specific content-related outcomes: faster publishing workflows, reduced editorial support tickets, migrations completed without search ranking loss, measurable cost reduction versus the prior stack. Reviews from editorial and marketing stakeholders — not only CTOs — are a particularly strong signal, because they confirm the agency built something that non-technical users can actually operate.Content modeling depthContent modeling — the architecture of content types, fields, relationships, and reusable components that underpins a headless implementation — is where genuine CMS expertise lives. Agencies that treat it as a configuration task rather than a design discipline produce implementations that work on launch day and degrade over the following 18 months as editors encounter the limits of the model.Platform-agnostic advisory evidenceThe strongest signal of client-oriented practice is evidence that an agency has explained when not to use their preferred platform. Published comparison content, case studies with documented platform selection reasoning, and the ability to articulate trade-offs honestly are all relevant markers.Migration track recordCMS migrations stress-test expertise. Moving from a traditional CMS to a headless platform, or from one headless platform to another, requires simultaneous competence in content architecture, data transformation, SEO preservation, and editorial change management. Verifiable migration cases with named clients, named platforms, and described scope are a reliable quality proxy.Editorial and non-technical stakeholder focusA CMS exists primarily for editors and content managers. Agencies that design for developer convenience but neglect editorial usability deliver technically clean systems that require IT involvement for routine content updates. Case studies mentioning editor training, content governance, and workflow design — and testimonials from marketing or content roles — are positive signals.Comparison table

Platform partnership status was treated as a neutral data point — useful for establishing platform familiarity. We've used a two-tier methodology: a qualification gate, then weighted scoring across seven criteria applied only to agencies that clear it.Qualification gateTo be ranked rather than listed as a special mention, an agency must have at least one verifiable, named production case with described scope, and at least one CMS platform in current, documented production use. This is a pass/fail check, not a scored criterion — it exists to separate agencies with real case evidence from agencies whose headless CMS capability is asserted on a services page but not demonstrated. DotStark, SCube, and SolGuruz are addressed as special mentions rather than ranked entries because they did not clear this gate on public evidence at time of research.Weighted scoring criteriaMulti-platform CMS portfolio with verifiable production cases: 22%Content modeling and content architecture depth: 20%Verified client outcomes from reviews and case studies, including editorial and marketing stakeholder testimony: 18%Platform-agnostic advisory evidence: 15%AI/GEO and structured-content readiness: 10%Migration track record with named scope and platforms: 10%Integration ecosystem breadth (DAM, CRM, search, eCommerce): 5%Platform-agnostic advisory evidence outweighs cms migration history in this framework: an agency that can articulate why a platform is wrong for a given client is a stronger signal of client-oriented practice than one that has simply moved a lot of content between systems.Evidence tiersEach criterion is scored against the strength of available evidence, not against a single best example:Tier 1: named client, named platform, described scope, and a measurable outcomeTier 2: named client and platform, described scope, no measurable outcomeTier 3: platform or capability claimed on-site, no named caseTier 0: no public evidenceA criterion score reflects the evidence tier across an agency's available case material as a whole, not its single strongest case study — a common inflation point in agency rankings, where one standout case creates the impression of consistent capability across the full client base.What we deliberately excludedTwo commonly used ranking inputs were left out of the weighted model, on purpose:Frontend framework breadth. The number of frontend frameworks a web agency supports measures web development versatility, not headless CMS or content architecture expertise. Framework count is relevant to a best-frontend-agency evaluation; in a headless CMS agency evaluation, weighting it heavily rewards general-purpose web shops over CMS specialists — the exact conflation this guide's selection criteria are designed to filter out.Platform partnership tier as a standalone criterion. Partnership and certification status can be acquired through business development spend rather than deployment volume, and measures commercial relationship rather than verified outcome. Rather than dropping this signal, we folded it into multi-platform portfolio and platform-agnostic advisory evidence above, where it belongs as supporting context rather than an independently scored input — avoiding both the double-counting risk and the disappearance of a legitimate (if weak) signal.Web agencies and headless CMS development companies that consistently recommended the same CMS regardless of client context were penalised under this framework.Top headless CMS agencies to hire1. FocusReactiveFocusReactive is an engineering-led headless CMS agency with official partnerships across Sanity, Storyblok, Contentful, and Payload CMS, production experience on Directus, and a vendor-agnostic selection process backed by documented case studies showing different platforms deployed for different client contexts.OverviewFocusReactive operates across offices in the Netherlands, the United Kingdom, and Poland, delivering across CET and ET timezones. Their work is built around four business outcomes: content systems that stay clean as editor count scales; genuine locale-specific publishing for multi-market organisations; marketing teams that launch campaigns without raising developer tickets; and businesses managing multiple brands from a single content architecture.Content modeling is treated as a primary design discipline rather than a setup task. Structured content types, reusable components, and governance rules are built into the schema from the start — so the system stays editorially consistent as teams and content volume grow. Permission structures, publishing approval chains, and content relationships are designed upfront to prevent structural debt as editorial teams expand.On AI SEO readiness, structured data and Schema.org markup are built into every project from day one. Content models are designed with machine readability alongside editorial usability — explicit entity relationships and clean semantic markup that allows AI crawlers to extract facts and cite the content as a canonical source, not only rank it in traditional search.Key services- Platform selection and content architecture consultancy- Headless CMS development and implementation across six platforms- CMS migrations from traditional and headless platforms- Localisation and multi-market content infrastructure- Next.js frontend development with performance and structured data built in- Technical audits of existing CMS and frontend stacks- Integration with DAMs, marketing tools, and third-party APIsFeatured case study — Arrive (EasyPark)Arrive, a mobility and transportation company, needed to consolidate a fragmented digital presence across multiple markets into a single unified platform that content editors could operate independently — across languages, countries, and product lines — without developer involvement.FocusReactive architected a composable platform on Storyblok and Next.js, deployed on Vercel, with a monorepo built in Turborepo housing a shared UI library, Storybook documentation, and a unified CI pipeline. The content model was built in Storyblok with structured schemas serving both editorial use and external systems.

Anything AgencyAnything Agency is a UK-based headless CMS development company with over a decade of headless-only delivery, Contentful certification, and enterprise case studies demonstrating editorial transformation alongside technical delivery.OverviewAnything Agency has operated exclusively in the headless space for over ten years. Their primary platform is Storyblok, where they hold the UK and Ireland Partner of the Year designation. They also maintain a Contentful practice with Contentful certification, and their integration work spans Algolia for search and Microsoft Dynamics 365 and Salesforce for CRM, giving their delivery scope broader reach than most single-platform agencies.Their client portfolio spans enterprise brands, high-traffic media, and B2B organisations. A 12-year partnership with Netmums — a high-traffic parenting platform — is a marker of long-term editorial usability: a relationship of that duration only persists if the editorial experience continues to serve the team.They publish comparison content between Contentful and Storyblok with genuine trade-off analysis, which is evidence of platform-comparative thinking within their two-platform scope.Key services- Storyblok implementation, governance, and editorial training- Contentful implementation and migration- Discovery and content strategy- CMS migration from Umbraco, WordPress, and other platforms- CRM and search integration (Salesforce, MS Dynamics, Algolia)- Performance optimisation and analytics setupVerified client outcomesAmtico: migration from Umbraco 7 to Storyblok, with sub-1-second load times and a 100% SEO score.

Their published content includes a headless CMS agency comparison guide. This headless CMS development company positioning is frontend-primary — the headless CMS serves the design and editorial experience rather than the other way around. This is a legitimate approach for a certain class of project, but it means content architecture and editorial governance may receive less emphasis than in agencies where CMS is the primary discipline.Key services- Headless CMS implementation across Contentful, Sanity, Strapi, Directus- Content modeling and CMS integration- Frontend development in React and Next.js- CMS migrations and legacy site modernisation- API integration and third-party connectionsCMS platformsContentful, Sanity, Strapi, DirectusStrengths- Multi-platform CMS portfolio across four headless platforms- Strong frontend and UX capability for design-driven implementations- Solid client review scores and referral rateLimitations- Frontend-primary positioning means content architecture and editorial governance are secondary concerns- Migration track record is less prominent than the top three agencies- CMS depth per platform appears shallower than agencies for whom headless CMS is the primary disciplineBest forOrganisations where the frontend experience is the primary deliverable and headless CMS is the supporting content infrastructure.

Roboto Studio is a Sanity and Next.js specialist with clients including Chelsea Piers (sports) and Jamb Ltd (antique furniture and interiors).

OverviewRoboto Studio is incorporated in the UK, with a stated mission to build the best editorial experiences on the web using Sanity and Next.js. Their positioning is anti-agency: fast, lean, and opinionated about the stack. Roboto Studio chose Sanity as the answer regardless of project type, which limits their value as a neutral CMS advisor, but not as a Sanity implementation partner. Where they differentiate is in editorial UX: content models, live previews, and AI-assisted workflows designed for editors and marketers to operate without engineering dependency.

DotStark AgencyDotStark is a Kentico-primary agency with Microsoft ecosystem depth across Azure, Dynamics 365, Power Platform, and SharePoint. Their headless CMS services page covers standard service categories without the platform specificity or content modeling depth of the ranked agencies. Most relevant for organisations already embedded in Kentico and Microsoft infrastructure.9. SCubeSCube development agency, from New York, operates in contexts where content management intersects with data compliance and enterprise security, with a focus on Strapi and Contentful. Most relevant for fintech, financial services, and compliance-heavy organisations where CMS architecture must account for data residency and security requirements. Note: limited public case evidence was available during research for this article.10. SolGuruzSolGuruz is a custom software development company with AI-assisted engineering. Headless CMS is one integration component within broader platform builds rather than a primary specialism. Relevant for organisations building custom platforms where a headless CMS is one of several moving parts, and development velocity is a priority alongside CMS functionality.How to choose the right headless CMS agencyThe question most buyers get wrongMost organisations approach agency selection with the CMS platform already decided, or with a strong preference formed from a single source. A competent headless CMS agency will push back on a platform choice if the evidence does not support it. If an agency immediately validates your existing preference without asking about your editorial team's technical confidence, your content volume and type, your localisation requirements, or your integration landscape — that is a red flag, not a sign of alignment.In-house versus agencyBuilding headless CMS capability in-house is appropriate when the platform is already implemented, the implementation is stable, and the ongoing work is primarily editorial tooling and maintenance. Agency expertise adds clear value when you are evaluating which platform to use, migrating from a legacy CMS, expanding to multiple markets or channels, or building content infrastructure that your editorial team needs to operate without developer support.Budget ranges for 2026CMS platform selection consultancy only: $5,000–$20,000New headless CMS implementation, mid-complexity, single market: $30,000–$80,000Legacy CMS migration with content modeling redesign: $50,000–$150,000Enterprise multi-market or multi-brand headless infrastructure: $150,000–$400,000+An agency that provides a fixed quote before understanding your content model and integration requirements has not understood your project.Questions to ask before hiring a headless agencyWhich headless CMS platforms have you delivered in production in the last 18 months? Can you name the clients or describe the scope?Have you ever recommended against a client's preferred platform? What was the reason?What does your content modeling process look like, and who leads it — a developer or a content architect?Can we speak with an editorial stakeholder from a past project, not only a technical lead?What happens when editors encounter a use case the CMS model does not support? Self-assessment: do you need a headless CMS agency?Score each question 1–5 (1 = does not apply, 5 = strongly applies):1. Your current CMS requires developer involvement for routine content updates2. You need to deliver content across more than one channel or market3. You are planning a migration from a legacy CMS4. Your team lacks experience in content modeling or API-first architecture5. Editorial team independence from the development team is a business requirementScore 20–25: agency partnership is strongly indicated.
Score 12–19: consider agency support for setup and migration phases with in-house handover.
Below 12: in-house implementation is viable with guidance.Red flagsThe agency's own website runs on the same CMS they recommend for every clientCase studies only mention frontend metrics with no editorial or content outcomesAll testimonials are from developers or CTOs — none from editorial or marketing stakeholdersThe agency cannot explain the trade-offs of their recommended platform against its alternativesPlatform partnership status is the primary evidence offered for expertiseWhat does a headless CMS agency do?A headless CMS agency designs, implements, and governs API-first content management systems — platforms where the backend content store is decoupled from the frontend presentation layer. Content lives in structured fields delivered via API, and the frontend is built independently using whatever framework the project requires.In practice this covers: platform selection and advisory; content modeling (designing the content types, fields, relationships, and reusable components that will underpin the editorial experience); implementation and configuration; integration with commerce platforms, DAMs, CRM systems, and search tools; migration from legacy CMS platforms; editorial training and workflow design; and ongoing governance and maintenance.The distinction between a headless CMS agency and a web development agency that uses a headless CMS is meaningful. Most development agencies have one or two default platforms they apply consistently. A headless CMS specialist has deep production experience across multiple platforms, treats content architecture as a primary deliverable, and makes platform recommendations based on the client's editorial and technical context.Headless versus traditional CMS: the practical differencesA traditional CMS couples content management with the presentation layer. The CMS generates HTML, controls page templates, and determines how content is displayed. This makes initial setup fast, but creates rigidity at scale. Changing the frontend requires changes to the CMS. Delivering content to a mobile app, a voice interface, or a second regional website requires duplication or workarounds.A headless CMS removes that coupling. Content is stored in structured fields and delivered via REST or GraphQL APIs. This frontend-first model is often described as headless web development, where websites and applications consume content from the CMS via APIs rather than being generated inside the CMS itself. Multiple frontends can draw from the same content store. Editorial and development teams can work in parallel. Platform upgrades on either side do not require simultaneous changes to the other.The practical benefits for 2026 deployments: faster frontend load times through static generation and edge caching; editorial independence from the development release cycle; structured content that can feed AI-driven personalisation and search; and genuine omnichannel delivery without content duplication.The practical costs: higher initial implementation complexity; content modeling decisions that require more upfront expertise to get right; and editorial experiences that vary significantly depending on platform choice and implementation quality.When to hire a headless CMS agency: Four scenarios1. Legacy CMS migration with SEO and content integrity requirementsOrganisations on monolithic CMS platforms with substantial indexed content face a migration risk that in-house teams frequently underestimate. A poorly executed migration to headless can result in permanent loss of organic search rankings. Headless CMS development companies with documented migration experience manage content transformation, URL mapping, redirect implementation, and structured data preservation as a single coordinated process.2. Omnichannel content delivery across markets or channelsWhen content needs to reach a website, a mobile app, a partner portal, and an internal tool from a single source, the content model must be designed for omnichannel delivery from the start. Retrofitting this into an existing implementation is expensive. An agency that has designed multi-channel content architectures will make different modeling decisions upfront than one that treats the website as the primary consumer.3. Editorial team autonomy without developer dependencyMany headless CMS implementations are technically clean but practically unusable without developer involvement for routine editorial tasks. Platform selection and content modeling decisions determine whether editors can work independently or whether every page change requires a ticket. Agencies with strong editorial design practice treat this as an architecture problem, not a training problem.4. Multi-market and multi-brand content infrastructureOrganisations expanding into new markets or managing multiple brands on a shared content platform face localisation, governance, and publishing workflow challenges that require deliberate architectural decisions. These include locale-specific content modeling, permission structures for different editorial teams, and content relationships that work across multiple frontends drawing from a shared source.FAQs What is a headless CMS agency?A headless CMS agency or headless CMS development company designs, implements, and governs API-first content management systems where the content backend is decoupled from the frontend presentation layer. A genuine headless CMS agency recommends the right platform for each client context, requiring practical expertise across multiple headless platforms.How is a headless CMS agency different from a web development agency that uses headless CMS?Most web development agencies have one or two default headless CMS platforms they apply consistently. A headless CMS specialist has deep production experience across multiple platforms, treats content architecture and editorial workflow as primary deliverables, and makes platform recommendations based on client requirements rather than tooling familiarity.Which headless CMS platforms are most widely used by specialist agencies in 2026?Contentful, Storyblok, and Sanity CMS cover most use cases. Contentful is strongest for enterprise structured content at scale. Storyblok is strongest when editorial visual editing and team autonomy are priorities. Sanity is strongest for developer-controlled custom content modeling. Payload CMS and Directus are increasingly chosen when the CMS and application need to share a codebase or database. DatoCMS is common in Jamstack and performance-critical deployments.How much does a headless CMS migration cost in 2026?A new implementation from a headless CMS development company for a mid-complexity site typically costs $30,000–$80,000. Migrations from legacy platforms, especially those involving content modeling redesign, usually range from $50,000–$150,000. Enterprise multi-market or multi-brand projects delivered by an experienced headless CMS development company typically start at $150,000. Platform licensing is separate, as cloud-native headless CMS solutions involve monthly or annual subscription costs that scale based on usage and feature tier.What should I look for in headless CMS agency case studies?The most informative case studies name the platform selected and explain why, describe the content modeling decisions made, document editorial outcomes (publishing speed, reduction in developer dependency, governance improvements), and include technical outcomes (load time, SEO stability through migration). Case studies that only describe the frontend redesign or list technology names without explaining content architecture decisions are not evidence of CMS expertise.Should I select a CMS platform before choosing a headless agency?Not necessarily. If you have a well-reasoned requirement that clearly aligns with a specific platform’s strengths, it can be sensible to choose the platform first and then find a headless CMS development company with deep expertise in it. However, if you are still evaluating platforms, it is often a stronger approach to work with an agency that has production experience across multiple options and can provide guidance without a commercial bias.What is the difference between a headless CMS and a composable DXP?A headless CMS manages and delivers content via APIs. A composable Digital Experience Platform assembles multiple best-of-breed components — content management, commerce, personalisation, search, DAM — into a unified architecture via APIs and a shared data layer. Headless CMS is typically the content management component within a composable DXP. The MACH Alliance framework (Microservices, API-first, Cloud-native, Headless) describes the architectural principles that composable DXPs follow.What is vendor-agnostic CMS selection?Vendor-agnostic CMS selection means an agency recommends the headless CMS platform that best fits each client's editorial workflow, technical stack, and content architecture requirements — rather than defaulting to the platform they are most familiar with or have a commercial incentive to sell. A genuinely vendor-agnostic agency has delivered production work across multiple CMS platforms, publishes honest trade-off comparisons between them, and can point to cases where they recommended against their preferred platform for a specific client context.This guide is editorially independent. No headless CMS development company paid for inclusion or placement. Platform partnership status was treated as a data point for platform familiarity, not as a ranking signal.
