This repository provides a configurable chat UI that connects to any LangGraph server. Users enter a deployment URL, assistant/graph ID, and optional LangSmith API key to authenticate. The app then routes messages to the LangGraph server and displays responses in a conversational interface. It supports both local development servers and deployed LangGraph cloud instances.
