Developer services

The MediaWiki ecosystem consists of many different pieces of software. Generally each piece of software is maintained in its own repository. These repositories can be found on:


 * gerrit.wikimedia.org &mdash; the Gerrit instance of Wikimedia
 * gitlab.wikimedia.org &mdash; the GitLab instance of Wikimedia (planned to replace Gerrit)
 * other websites such as github.com

Other important services include:


 * phabricator.wikimedia.org &mdash; the Phabricator issue tracker
 * doc.wikimedia.org &mdash; for auto-generated documentation

The main MediaWiki source code is maintained in mediawiki/core on Gerrit.

Note that while the Gerrit repositories are mirrored to GitHub you cannot contribute there, you have to contribute on Gerrit.

You can search the code of many projects with MediaWiki code search (see Codesearch for more info).
