- Agent 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 Agent 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 Agent Server deployments.
- Data plane: The runtime layer that executes your graphs, including Agent Servers, their backing services (PostgreSQL, Redis, etc.), and the listener that reconciles state from the control plane.
