- LangGraph Server: Defines an opinionated API and runtime for deploying graphs and agents. Handles execution, state management, and persistence so you can focus on building logic rather than server infrastructure.
- LangGraph CLI: A command-line interface to build, package, and interact with graphs locally and prepare them for deployment.
- Studio: A specialized IDE for visualization, interaction, and debugging. Connects to a local LangGraph Server for developing and testing your graph.
- Python/JS SDK: The Python/JS SDK provides a programmatic way to interact with deployed graphs and agents from your applications.
- RemoteGraph: Allows you to interact with a deployed graph as though it were running locally.
- Control Plane: The UI and APIs for creating, updating, and managing LangGraph Server deployments.
- Data plane: The runtime layer that executes your graphs, including LangGraph Servers, their backing services (PostgreSQL, Redis, etc.), and the listener that reconciles state from the control plane.
LangSmith components
When running the self-hosted LangSmith with agent deployment, your installation includes several key components. Together these tools and services provide a complete solution for building, deploying, and managing graphs (including agentic applications) in your own infrastructure:
