Deploying Your Python App on Heroku in Minutes

Building a Python app is exciting—but sharing it with the world is even better. Heroku is a beginner-friendly platform that lets you deploy your Python web apps in just a few minutes. This guide will walk you through the step-by-step process to get your project online fast.

Why Deploy on Heroku?

Easy setup with Git
Free tier available for small projects
Supports Python, Flask, Django, and more
Great for showcasing projects and prototypes

Prerequisites

Before you begin, make sure you have:

A working Python web app (e.g., built with Flask or Django)
Python installed on your system
Git installed
A free Heroku account

Step 1: Prepare Your App

For Flask apps, make sure your main file looks something like this:

python

Copy code

from flask import Flask

app = Flask(__name__)

@app.route(“/”)

def home():

return “Hello, Heroku!”

if __name__ == “__main__”:

app.run()

Step 2: Create Required Files

requirements.txt

bash

Copy code

pip freeze > requirements.txt

Procfile

Create a file named Procfile (no extension) with this line:

makefile

Copy code

web: python app.py

✅ Replace app.py with your actual entry file name.

Step 3: Initialize Git and Commit

bash

Copy code

git init

git add .

git commit -m “Initial commit”

Step 4: Deploy to Heroku

Login to Heroku:

bash

Copy code

heroku login

Create a Heroku App:

bash

Copy code

heroku create your-app-name

Push Your Code:

bash

Copy code

git push heroku master

Open in Browser:

bash

Copy code

heroku open

Your app should now be live!

Troubleshooting Tips

Make sure your requirements.txt includes gunicorn if needed for production
Use heroku logs –tail to view real-time logs
Use heroku ps:scale web=1 if the dyno is sleeping

Practice Tip

Try deploying a simple to-do app, chatbot, or portfolio site. Heroku makes it easy to test real-world deployment scenarios—even as a beginner.
