Can I self-host a LangGraph app without a key?

[cf-sewe]

I am in the process of migrating my chat app from LangServe to LangGraph and want to self-host it in Docker (as before).
Is this deployment scenario still valid? I only have a free LangSmith account.

From documentation I think it will be possible to run langgraph build, but running the actual LangGraph Docker container seems to require an API key. What does LANGGRAPH_AUTH_TYPE=noop do in this context?

What options do I have?

Also looking for a solution of a fully self-hosted and self-managed solution for deploying my LangGraph agents - no LangSmith monitoring desired. Working on researching this right now - will report back.

In the past I had used FastAPI to create an endpoint in which I called graph.astream_events() directly. Unsure if a 'proper' LangGraph deployment will allow for free usage.
