# 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 **390**
open-source Python applications arranged by topic, with links to
repositories, docs, and more, generated from [structured
data](https://github.com/mahmoud/awesome-python-applications/blob/master/projects.yaml)
using [apatite](https://github.com/mahmoud/apatite). If you have one
to add or find some information missing, [please let us
know](https://github.com/mahmoud/awesome-python-applications/issues)!
Read [**the announcement post**](http://sedimental.org/awesome_python_applications.html) to learn more about this list.
Subscribe to [**the RSS/Atom feed**](https://raw.githubusercontent.com/mahmoud/awesome-python-applications/master/atom.xml) to see new applications added.
