Deploy guides

Deploy a Flask app

Deploy a Flask app from GitHub in about a minute. Rimbra detects Flask, 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 Flask in six steps

  1. 01

    Push your Flask 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 an app.py, main.py, server.py or run.py and runs pip install, then gunicorn. 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.

app.py
from flask import Flask

app = Flask(__name__)

@app.get("/")
def home():
    return "Hello from Rimbra"

Questions

Can I host a Flask 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 Flask 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.
