This document compares the Flask and Django web frameworks. It discusses that Flask is smaller and more flexible than Django as it only imports what is needed and allows developers to organize code freely. Flask also has fewer constraints. The document suggests Flask may be better than Django for situations where the data is unusual and the ORM does not fit, or if more flexibility is needed than what Django provides out of the box. In conclusion, both Flask and Django are great frameworks to use, depending on the specific needs and preferences of the developer.
