<commit_before>Zulip architectural overview
============================

Key Codebases
-------------

The core Zulip application is at
[<https://github.com/zulip/zulip>](https://github.com/zulip/zulip) and
is a web application written in Python 2.7 (soon to also support
Python 3) and using the Django framework. That codebase includes
server-side code and the web client, as well as Python API bindings
and most of our integrations with other services and applications (see
[the directory structure guide](../overview/directory-structure.html)).

[Zulip Mobile](https://github.com/zulip/zulip-mobile) is the official
mobile Zulip client supporting both iOS and Android, written in
JavaScript with React Native, and
[Zulip Desktop](https://github.com/zulip/zulip-electron) is the
official Zulip desktop client for macOS, Linux, and Windows.<commit_msg>docs: Update architecture-overview to point to Python 3.x.<commit_after>Zulip architectural overview
