CopilotKit is an open-source frontend SDK for building agent-native applications with generative UI, shared state, chat interfaces, and human-in-the-loop workflows. It connects any AG-UI-compatible agent backend (LangChain, Claude Agent SDK, PydanticAI, etc.) to React, Angular, Vue, React Native, Slack, and Microsoft Teams surfaces.

Use cases

• add an ai chat copilot to my react app
• render agent tool calls as react components in the ui
• build a chatbot ui connected to my langchain agent
• let ai agents share state with my frontend
• add human-in-the-loop approval to agent workflows
• expose my agent in slack or microsoft teams
• build generative ui with claude agent sdk

When to choose

• you want production-ready chat or generative UI components wired to your own agents
• you need one agent to reach web, mobile, and messaging surfaces
• you want frontend tools, shared state, and human-in-the-loop out of the box
• you use an AG-UI-compatible agent framework like LangChain, Claude SDK, or PydanticAI

When to avoid

• you only need a raw LLM API client without UI components
• you are not using React-family or supported frontend frameworks
• you want a fully self-contained agent runtime with no external service dependency
• you need a non-JavaScript frontend stack
