Commands

LangGraph CLI provides the following core functionality:

Command	Description
langgraph build	Builds a Docker image for the LangGraph API server that can be directly deployed.
langgraph dev	Starts a lightweight development server that requires no Docker installation. This server is ideal for rapid development and testing.
langgraph dockerfile	Generates a Dockerfile that can be used to build images for and deploy instances of the LangGraph API server. This is useful if you want to further customize the dockerfile or deploy in a more custom way.
langgraph up	Starts an instance of the LangGraph API server locally in a docker container. This requires the docker server to be running locally. It also requires a LangSmith API key for local development or a license key for production use.
