Deployment Options

While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well. Some of the options available for properly running Flask in production are documented here.

If you want to deploy your Flask application to a WSGI server not listed here, look up the server documentation about how to use a WSGI app with it. Just remember that your Flask application object is the actual WSGI application.
