Frédéric Barthelet

Fred is a passionate and (very 😅) opinionated builder. He's been in the infrastructure space, and in particular in serverless technologies back when they were new-age. He built Lift, to help people ship piece of infrastructure without previous knowledge, and then built Revant to help those same people reduce their newly generated infra cost... He's also been part of the AWS community builder team for 5 years. He's now building with Alpic the missing infrastructure layer for the new agentic internet where AI consume services instead of human. He's working full time on Skybridge, a new open-source framework to build ChatGPT and MCP Apps.

Build ChatGPT Apps with Skybridge
Workshop
A new ecosystem of apps is emerging inside generalist conversational agents like ChatGPT and Claude. These apps serve as a direct digital storefront for brands. They serve as a compelling alternative to traditional mobile and web applications for the billion users who now begin their online journey in a chat.

AI apps are built on standards like Apps SDK, MCP Apps, and MCP UI. They all rely on MCP as the underlying protocol to expose context and tools, while adding a human-facing presentation layer in the form of UI widgets.

Building these React apps introduces a genuinely new set of challenges: you're no longer designing for a user interacting with a UI alone, but for a three-way dynamic between a human, a UI, and a model. Every interaction must account for whether it originates from a click on a widget or a message typed in the chat.

Skybridge is the full-stack TypeScript framework built on React that we created at Alpic to help developers around the world ship these new apps at the speed of light.
