Flask is not a web server. It is a micro web application framework, a set of tools and libraries that make it easier and prettier to build web applications. Flask comes with Werkzeug, a WSGI utility library that provides a simple web server for development purposes. While Flask's development server is good enough to test the main functionality of the app, we shouldn't use it in production. While lightweight and easy to use, Flask's built-in server is not suitable for production as it doesn't scale well and by default serves only one request at a time.
