<p>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.</p>
<p>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.</p>
<p>This document is an always-growing list of <strong>404</strong> open-source Python applications arranged by topic, with links to repositories, docs, and more, generated from <a href="https://github.com/mahmoud/awesome-python-applications/blob/master/projects.yaml">structured data</a> using <a href="https://github.com/mahmoud/apatite">apatite</a>. If you have one to add or find some information missing, <a href="https://github.com/mahmoud/awesome-python-applications/issues">please let us know</a>!</p>
<p>Read <a href="http://sedimental.org/awesome_python_applications.html"><strong>the announcement post</strong></a> to learn more about this list.<br/> Subscribe to <a href="https://raw.githubusercontent.com/mahmoud/awesome-python-applications/master/atom.xml"><strong>the RSS/Atom feed</strong></a> to see new applications added.</p>
