Developers/Maintainers

Maintainers
This is a list of developers who know the most about, and maintain, MediaWiki core, key extensions, and Wikimedia servers.

To be listed as a maintainer a person has to have +2 access to the relevant Git repository and regularly respond to bug reports and changeset review requests.

If you are a maintainer, please consider using configuring Gerrit to send you an email for new patchsets in a repository. Alternatively you can add yourself to the Gerrit Reviewer Bot which will automatically add you as a review to each new patchset.

Anyone can list themselves as in training to maintain something, signaling that they want to learn more and achieve maintainership within the next year.

Stewards
Code stewards are ultimately responsible for the development policies, support, and overall health of the code in question. As MediaWiki continues to grow and become further depended on by millions of users, it has become increasingly important that the code-base remains healthy while also enabling the continue evolution of its capabilities. Stewards enable this by committing to a base level of support such as bug fixes and code reviews. For more information regarding stewardship, please see Development policy/Code Stewardship.

MediaWiki core

MediaWiki extensions deployed by WMF

Upstream projects and libraries
There are many upstream projects on which MediaWiki, extensions, and/or Wikimedia depend. Some of them were "invented here", as stand-along libraries, or split out as part of the Library infrastructure for MediaWiki project. Some of them are widely-used third party tools to which community members provide improvements or support. Others are merely used with gratitude.

Key extensions
Mostly extensions used by over ~400 standalone wikis.
