Quick Start (5 minutes)

The fastest way to get LangGraph Chat UI running locally with no authentication.

Prerequisites

• Node.js 22.13+, pnpm 10+ (the project pins pnpm 11.5.2)
• A LangGraph server running (e.g. langgraph dev)

Steps

git clone https://github.com/teddynote-lab/langgraph-chat-ui.git
cd langgraph-chat-ui
pnpm install
pnpm launch   # interactive setup — select "standalone" mode

If pnpm is unavailable or does not use the pinned version, run corepack enable and retry.

Or manually:

cd frontend
cp .env.example .env
# Edit .env: set NEXT_PUBLIC_API_URL to your LangGraph server
pnpm dev

Open http://localhost:3000.
