PythonAnywhere is a cloud-based platform that allows you to deploy and host Python web applications, including Flask apps. In this guide, we'll walk you through the process of hosting your Flask app on PythonAnywhere. You'll learn how to create a PythonAnywhere account, prepare your Flask app for deployment, deploy it to PythonAnywhere, and make it accessible to the world.

Step 1: Create a PythonAnywhere Account

If you don't already have a PythonAnywhere account, sign up for one on the PythonAnywhere website. PythonAnywhere offers free and paid plans, making it accessible for various types of projects.

Step 2: Prepare Your Flask App

Before deploying your Flask app to PythonAnywhere, ensure it's ready for production. This involves:

  • Updating your Flask app's configuration for production (e.g., setting "DEBUG" to "False").
  • Creating a requirements.txt file with a list of dependencies.
  • Adding a file for PythonAnywhere compatibility.
  • Setting up a production-ready database if needed.
  • Securing your app with proper access controls and handling sensitive information securely.

Step 3: Deploy Your Flask App to PythonAnywhere

Here are the general steps to deploy your Flask app to PythonAnywhere:

  1. Log in to your PythonAnywhere account and open the dashboard.
  2. Create a new web app by following the provided instructions.
  3. Access the Bash console in PythonAnywhere to clone your GitHub or GitLab repository or upload your app files manually.
  4. Create a virtual environment for your app with the command mkvirtualenv --python=/usr/bin/python3.8 myenv, replacing "myenv" with your virtual environment name.
  5. Install the app's dependencies using pip install -r requirements.txt.
  6. Configure the web app to use your virtual environment and specify the path to your Flask app's main script (e.g.,
  7. Reload your web app to start it.

Step 4: Access Your Deployed App

Once your app is successfully deployed, you can access it using the URL provided by PythonAnywhere. Your app will be live and accessible to the world. Share the URL with others to showcase your Flask app.


PythonAnywhere is a user-friendly platform for hosting Python web applications, making it an excellent choice for Flask apps. By following these steps and using PythonAnywhere's tools, you can easily deploy your Flask app and make it accessible online for users to enjoy.
