A Next.js web application for chatting with any LangGraph agent (Python or TypeScript) through a chat interface. It connects to a LangGraph server via a deployment URL and assistant/graph ID, with a hosted version available at agentchat.vercel.app.
Use cases
- test my langgraph agent in a chat ui
- chat interface for langgraph server
- demo my llm agent to stakeholders
- quickly spin up a frontend for my ai agent
- debug agent message streaming
- hosted chat playground for langchain agents
When to choose
- you're building agents with LangGraph and need a ready-made chat frontend
- you want to demo or test LangGraph deployments without writing UI code
- you need streaming message rendering out of the box
When to avoid
- your agents don't run on a LangGraph server with a messages key
- you need a fully customized production chat product
- you want a backend-agnostic chat UI not tied to the LangChain ecosystem
