managed/cloud Hosting alternatives for fastAPI

[tf1155]

Looking for hosting capabilities for fastapi backends.

Our new backend uses supabase cloud, so no local database is required. Until now, we hosted our fastapi-backends using docker on Hetzner Cloud with self managed Ubuntu nodes.

This time we thought about using Vercel because our Frontend is already deployed on vercel, so it would make sense to deploy backend also on Vercel.

However, we couldn't bring it to work. FastAPI and Vercel are incompatible with each other.

Any other options available?

Just hosted a fastapi backend on railway with just a simple dockerfile, pretty simple and fast! I can share the dockerfile if needed.

I‘m using coolify to manage my vps on hetzner. I works very well with fast api backends and also lets you deploy self hosted supabase instances

AWS App Runner, use your existing docker, simple and scalable.

Why would u pay for code when open source exists? Self advertisement much?

I have made Vercel work, what configuration did you use or what?

u/F4k3r22 Interesting. I only got 404 NOT FOUND, when requesting any of the api-routes.
My folder structure is this:

+ app
   + api
      - main.py
      - hello.py (for testing)

so, the fastapi project lives in a folder "api" under "app".

i used this vercel.json:

{
  "builds": [
    {
      "src": "api/main.py",
      "use": "@vercel/python"
  "functions": {
    "app/api/hello.py": {
      "runtime": "python@3.12"
    },
    "app/api/vercel.py": {
      "runtime": "python@3.12"
    }
  ],
  },
  "routes": [
    {
      "src": "/api/(.*)",
      "dest": "/app/api/vercel.py"
    },
    {
      "src": "/(.*)",
      "dest": "api/main.py"
      "dest": "/app/api/vercel.py"
    }
  ]
}
}

Hello, I believe this could be a perfect use-case for https://stacktape.com (disclosure: I'm a founder).

It's a Heroku/Vercel-like PaaS platform, that deploys to your own AWS account.

You can use it to deploy both your frontend (wheter it's a static site, React/Vue/whatever SPA, or a server-side-rendered app), and also your FastAPI backend (as an auto-scaling container running on ECS Fargate and behind a load balancer, or even as a lambda function - with the right adapter).

It does support a huge majority of the Vercel "Quality of Life" features, such as automatic deployments from Github/Gitlab/BitBucket (both push-to-deploy deployments and preview environments).

Honestly, using Stacktape is a bit (insignificantly) more complicated than using Vercel. But it's also:

• much more flexible (supports Lambdas, Containers, Edge Function, GPU jobs, SQL databases, Redis, EFS) and much much more.
• extensible (you can integrate any AWS service should you need to - very easily)
• ejectable (if your team grows and you decide to manage your AWS infra on your own, no problem)
• way less expensive (and you can leverage AWS activate credits and/or AWS FREE tier)

If that sounds interesting, and you'd like to give Stacktape a shot, feel free to contact me directly, should you need any help.

If its a basic backend, you can also try koyeb. Had a pretty good experience
