CopilotKit

Open-source frontend stack for building AI agents and copilots inside your own product

Pre-built and headless UI components

Ship a working copilot UI in minutes with drop-in components for React, Angular, Vue, iOS, and Android, or go fully headless for total control over rendering.

AG-UI protocol and framework connectors

A general-purpose bi-directional link between your app and any agent backend, with integrations for the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, Mastra, and many more.

Generative UI inside your product

Agents return real UI — charts, forms, tables, and approval prompts rendered with your own design system on the same screen the user is already working in.

Shared state, frontend tools, and HITL approvals

Let agents read and write application state, call your frontend functions, and pause for human approval before sensitive actions are executed.

+Open source with a large developer community and active framework coverage
+Works with many agent backends through the open AG-UI protocol, avoiding vendor lock-in
