How to Deploy a Python Flask App to the Cloud

Flask is the go-to for Python APIs. Here’s how to deploy yours in minutes.

Prerequisites

• Flask app with requirements.txt
• GitHub repo
• Remoud account (free)

Prepare Your App

pip freeze > requirements.txt

Ensure your app reads the PORT env var:

import os
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello():
    return 'Hello from Remoud!'

if __name__ == '__main__':
    port = int(os.environ.get('PORT', 5000))
    app.run(host='0.0.0.0', port=port)

Deploy on Remoud

1. Push to GitHub
2. Select repo in Remoud dashboard
3. Set start command: python app.py
4. Click Deploy

Django

Same process. Start command: gunicorn myproject.wsgi:application --bind 0.0.0.0:$PORT
