Enable dual deployment — both self-hosted (Render) and LangGraph Platform work from the same codebase. Conditional checkpointer skips BoundedMemorySaver when LANGGRAPH_CLOUD=true, frontend passes x-api-key header when LANGSMITH_API_KEY is set, and langgraph.json no longer references .env.
Remove agent service from render.yaml (frontend-only on Render), switch
LANGGRAPH_DEPLOYMENT_URL from Render service discovery to manually-set
env var pointing to LangGraph Platform. Fix bool("false")==True bug in
LANGGRAPH_CLOUD detection, add startup log for platform mode. Rewrite
deployment docs with langgraph deploy CLI workflow and split deployment
guide.
Step-by-step runbook for migrating agent from Render to LangGraph Platform — covers dev deploy, verification, merge, production deploy, rollback, and cleanup.
…r self-hosted LangGraphHttpAgent speaks the AG-UI HTTP protocol which only the self-hosted FastAPI server exposes. LangGraph Platform uses a different API, causing 404s. Switch to LangGraphAgent (native LangGraph SDK) when LANGSMITH_API_KEY is set, keeping LangGraphHttpAgent for local dev.
