Developers/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.
