Use when

Engineering teams that picked LangGraph for complex stateful agents and want managed deployment without running Postgres, queues, and auth themselves.

Avoid when

Teams not already on LangGraph — switching frameworks for the hosting isn't worth it. Consider Modal or custom infra.

What is LangGraph Platform?

LangGraph Platform (formerly LangGraph Cloud) is LangChain's managed hosting for LangGraph agents — the stateful, controllable agent framework used by Replit, Uber, and LinkedIn. The platform handles deployment, scaling, state persistence, streaming APIs, and the Agent Inbox for human-in-the-loop approvals. Targets teams that built with LangGraph and don't want to run the infrastructure themselves.
