Bring your A2A agents
into any app
CopilotKit is an open-source framework that connects your app to A2A agents. Give your agents chat, generative UI, human-in-the-loop, rich threads, automatic learning and more.
Build with A2A
A2A gives your agents a protocol for talking to each other. What it does not give you is the surface your users talk through. The capability below builds on what your A2A agents already emit.
Declarative UI
Your agents describe what to show rather than how to render it. CopilotKit turns those A2UI descriptions into React components in your own app.
Read the docsChat surfaces, headless UI, frontend tools and shared state work with A2A too. And more

Connect your agent
A2A setup starts from a working example rather than a snippet: clone the repository below, then follow the quickstart to point it at your own agents.
