Yes, absolutely you can deploy a LangGraph agent on a VPS or AWS.
I’ve shared some details about my setup in this other post:
Has anyone integrated a multi-agentic system in LangGraph with FastAPI?
Unfortunately, I can’t share my full codebase, but I’ve posted a few public examples in that thread.
If you’re already comfortable building containerized FastAPI apps on AWS (ECS/Fargate), the deployment should be pretty straightforward.
Let me know if you have any specific questions. Happy to help point you in the right direction.
