Deprecation notice: Agent Builder
OpenAI Developer Community
June 8, 2026
Ive just migrated from the Agent Builder backend to my own custom server for hosting the Chatkit backend, using Fast API. Does anyone know where I can host and deploy this server, given my requirement of minimal costs? (I was currently evaluating AWS LightSail, Render, Fly.io, etc…).
