What is Skybridge?

Skybridge is a full-stack TypeScript framework designed specifically for building MCP Apps—interactive applications that run inside AI assistants like ChatGPT and Claude. It handles the entire infrastructure stack, from MCP server configuration and view rendering to client compatibility and testing tunnels, so developers can focus purely on building features. With over 500,000 downloads and dozens of apps already in the stores, Skybridge lets you code once and ship everywhere.

Who it's for

• React developers who want to build interactive apps for AI assistants without learning a new paradigm—if you know React, you've got Skybridge.
• AI product teams building the next generation of conversational UIs that need a reliable, production-ready framework to ship MCP apps fast.
• Coding agents and power users who leverage tools like Claude Opus and Codex to rapidly prototype and deploy MCP apps end-to-end.

Key features

Complete local development environment

Skybridge provides a dev server with Hot Module Reload, a local emulator, and an instant public tunnel. Edit a tool or widget and see the change in your MCP client instantly—no restarts, no redeploys.

tRPC-style type inference

The framework offers type-safe inference from MCP server tool definitions directly to React views. This means your tool schemas and UI components stay perfectly in sync without manual type wiring.

Intuitive hooks and state management

Skybridge includes react-query style hooks with advanced state management built in. The developer experience is designed to feel familiar to anyone who has worked with modern React patterns.

Production-ready app examples

Get started quickly with template apps for e-commerce, travel, SaaS, and other common use cases. One user reported going from the template repo to three production-grade demos for partners in just 24 hours.

What stands out

"Code once, ship everywhere—Skybridge abstracts implementation differences so your app runs seamlessly in Claude, ChatGPT, VSCode, and any MCP-compatible client."

This cross-client compatibility is the core differentiator. Instead of building and maintaining separate versions for each AI assistant, Skybridge handles the platform differences automatically. The framework is also recommended in OpenAI's documentation and developer blog, and it's actively shaped by the MCP app developer community through its MIT-licensed, open-source model.

Worth checking out if…

You're building interactive tools or conversational UIs that need to run inside AI assistants like ChatGPT or Claude. If you want a framework that handles MCP server infrastructure, client compatibility, and developer tooling out of the box—so you can focus on your app's features instead of plumbing—Skybridge is worth a serious look.
