There are definitely people deploying FastAPI projects with Vercel! Artha.ai and the Next.js FastAPI Starter are two recent examples shared in other posts.
But you bring up a good point. Not every app is necessarily going make sense a serverless environment. I have seen people modify apps designed for traditional servers (e.g. Express, Python) to work with Streaming Functions. I’ve also see people deploy frontends with Vercel while using a separate service or backend hosted elsewhere.
I am also curious to know how others handle these AI app challenges and what suggestions or feedback everyone is willing to share here.
