When I first saw the description of the python package Cherrypy, my first question is “another web framework? what is the difference between Cherrypy and Flask?”. Then I typed “flask vs” and “cherrypy vs”, you can see there are a whole family of packages in Python to offer similar functionalities, like flask, cherrypy, bottle, pyramid, beaker, tornado, django..etc.

Here is an interesting Stackoverflow conversation that explained some difference between Flask and Cherrypy and seems like you can use the Flask as the framework and Cherrypy as the backend server to guarantee the “solid rock” performance.
