agent-chat-ui is a web application from LangChain for chatting with any LangGraph agent, whether written in Python or TypeScript. It provides a chat interface you can point at your agent to interact with it.

You need a ready-made chat frontend for testing or demoing LangGraph agents without building one yourself.

Use it to

Chat-test a LangGraph agent during development
Demo agents to stakeholders through a browser UI
Serve as a frontend for both Python and TypeScript agents
Fork the UI as a starting point for your own agent app
