Deployment
In one line
Ship with an always-on server, saved state, and streaming.
Options
- LangGraph Platform — managed API endpoint, persistence, streaming, scaling.
- Self-host — FastAPI + Postgres checkpointer. More control, more work.
- Deep Agents Deploy — path for shipping Deep Agents (2026).
Before shipping: LangSmith tracing on, a real database checkpointer (not in-memory), risky tools behind human approval.
