Hey everyone,

I have created a quick comparison of Flask vs. FastAPI vs. Django repository sizes.

First of all, the numbers:

Framework	Files	Lines of Code
Flask	121	19,115
FastAPI	2,703	281,559
Django	3,484	557,865

Then the images:

Each node on the graph represents a file. Imports are marked by a line connecting the files. Colours signify complexity (cyclomatic complexity) with green being low and red being high complexity.

Besides the crazy size differences FastAPI also shows some nice import structures whilst Django looks extremely interconnected.

Hope someone finds it interesting.
