Awesome Python Applications

Case studies in successfully shipping Python software

As developers, we spend our days with code. The site you're reading this on is mostly modules, packages, libraries, frameworks, and the like. But users see applications.

When building our own applications, open-source Python applications are a gold mine of practical patterns that we know work together. A production application is worth a thousand blog posts and Stack Overflow answers.

This document is an always-growing list of 426 open-source Python applications arranged by topic, with links to repositories, docs, and more, generated from structured data using apatite. If you have one to add or find some information missing, please let us know!

Read the announcement post to learn more about this list.
