Benchmarks are everywhere, but production rarely looks like a benchmark.

This talk compares Node.js, Deno, and Bun from a pragmatic, production-first perspective: debugging, observability, deployment, cold starts, and the kind of edge cases that only appear when real users and real systems are involved.

This talk has been presented at Node Congress 2026, check out the latest edition of this JavaScript Conference.

How Bun Makes Building React Apps Simpler & Faster

Top Content

Jarred Sumner

Creator of Bun.

BUN is a modern all-in-one JavaScript runtime environment that achieves new levels of performance. It includes BUN dev, a fast front-end dev server, BUN install, a speedy package manager, and BUN run, a fast package runner. BUN supports JSX, has optimized React server-side rendering, and offers hot module reloading on the server. The priorities for BUN include stability, node compatibility, documentation improvement, missing features in BUN install, AST plugin API, native Windows support, Bundler and Minifier optimization, and easier deployment to production. BUN's AST plugin API allows for bundle-time JavaScript execution and embedding code, potentially inspiring new frameworks.

Node.js Compatibility in Deno

Bartek Iwanczuk

Deno core team member

Deno aims to provide Node.js compatibility to make migration smoother and easier. While Deno can run apps and libraries offered for Node.js, not all are supported yet. There are trade-offs to consider, such as incompatible APIs and a less ideal developer experience. Deno is working on improving compatibility and the transition process. Efforts include porting Node.js modules, exploring a superset approach, and transparent package installation from npm.

Eval all the strings! - Hardened JavaScript

Zbyszek Tenerowicz

One of the oldest members of meet.js Poland community.

NPM packages can be potentially dangerous, so it's important to be proactive in managing them. Lava Mode allows you to detect and investigate suspicious packages before deploying your app. Lavamote prevents unauthorized access to sensitive resources by isolating dependencies and using hardened JavaScript. Lava Mode makes it easier to analyze obfuscated files and understand their actions.

Roll you own JavaScript runtime

Bartek Iwanczuk

Deno core team member

This Talk introduces Deno, a custom JavaScript runtime similar to Node.js, and discusses the benefits of using a custom runtime. It explores the process of building a custom runtime with Deno in Rust, including the integration with Cargo and the ability to mix and match crates and APIs. The Talk also covers the implementation of the setTimeout function in both Run.js and Runtime.js, and provides examples of how to fix errors and implement additional functions. Overall, the Talk highlights the flexibility and possibilities of creating custom runtimes with Deno.

David Mark Clements

Learn how to rapidly build peer-to-peer applications with Pear Runtime. No servers required. Understand peer-to-peer paradigms and construct applications from well-defined building blocks. This workshop will cover how to create both Desktop and Terminal applications (with discussion for Mobile) that work entirely peer-to-peer from anywhere in the world. By the end of this workshop you should know how to build a new type of highly scalable application with entirely reduced infrastructural costs (~0) along with suitable architectures and best practices for peer-to-peer applications. From the creator of Pear Runtime and the company that brings us keet.io.
