CopilotKit is a full-stack SDK for building agentic applications with generative UI. AI agents can dynamically render React components, manage shared application state, and pause for human-in-the-loop confirmation. Maintains the AG-UI Protocol (adopted by Google, LangChain, AWS, Microsoft) for standardized agent-frontend communication. Supports React and Angular frontends with Python and TypeScript backends. Integrates with LangGraph, CrewAI, and any LLM provider.
