PythonAnywhere is beginner-friendly for Flask hosting.

Typical steps (conceptual)

• Create a web app (Flask)
• Create a virtualenv on PythonAnywhere
• Install requirements
• Configure the WSGI file to point to your Flask app

WSGI file idea

PythonAnywhere provides a WSGI config file where you import your app:

from myapp import create_app
 
application = create_app()

from myapp import create_app
 
application = create_app()

Note: PythonAnywhere uses applicationapplication as the variable name.

Common pitfalls

• wrong virtualenv selected
• missing packages
• incorrect module import paths
• static files not configured

Good fit

PythonAnywhere is great for:

• learning deployments
• small projects

For advanced ops (containers, autoscaling), use a cloud VM or container platform.
