Deploy a FastAPI app

Deploy a FastAPI app from GitHub in about a minute. Rimbra detects FastAPI, builds it and gives it a live HTTPS address, with a managed database, your own domain, an Email API and a WhatsApp API in the same account.

Deploy FastAPI in six steps

  1. 01

    Push your FastAPI project to a GitHub repository.

  2. 02

    Sign in to Rimbra, choose New project and import the repository. Rimbra asks GitHub for access to the repositories you pick.

  3. 03

    Rimbra sees a requirements.txt or pyproject.toml and a main.py with app = FastAPI() and runs pip install, then uvicorn main:app on PORT. Change the root directory or the commands in Settings if your project needs it.

  4. 04

    Paste your .env into Variables. Every line becomes a variable, available on the next deploy.

  5. 05

    Deploy. The build log streams line by line, and your app goes live at your-project.rimbra.live (or .xyz or .click, your choice) over HTTPS.

  6. 06

    Optional: buy or connect a domain, and Rimbra points it at your app with HTTPS issued automatically.

What your app needs

One rule for servers: listen on the port in the PORT environment variable. Rimbra sets it and routes your address to it.

main.py
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def home():
    return {"hello": "Rimbra"}

Questions

Can I host a FastAPI app for free?

Yes. Rimbra’s Free plan needs no card and includes 4 projects, 1 database, 200 build minutes and 50 GB of bandwidth a month, with a free HTTPS address for each project.

Does every push redeploy my FastAPI app?

Yes. Every push to your production branch builds a new version. It goes live only when it answers, so visitors never see a broken release, and you can roll back to an earlier build instantly.
