Alpha Notice: These docs cover the v1-alpha release. Content is incomplete and subject to change.For the latest stable version, see the current LangGraph Python or LangGraph JavaScript docs.
You can use a prebuilt chat UI for interacting with any LangChain agent through the Agent Chat UI. Using the deployed version is the quickest way to get started, and allows you to interact with both local and deployed graphs.

​
Run agent in UI

First, set up LangGraph API server locally or deploy your agent on LangGraph Platform. Then, navigate to Agent Chat UI, or clone the repository and run the dev server locally.
UI has out-of-box support for rendering tool calls, and tool result messages. To customize what messages are shown, see the Hiding Messages in the Chat section in the Agent Chat UI documentation.
