The Extension Matrix provides an overview of the extensions on this site. Note that this list is by no means exhaustive: it only covers pages in the Extension namespace that use Template:Extension. There may be some more in Category:Extensions, most older ones in meta:Category:MediaWiki extensions, and several extension in SVN are not listed anywhere else - not to speak of things forgotten on some userpage somewhere.

The Extension Matrix is updated automatically by User:DuesenBot every 24 hours. Any changes you make below will be lost on the next update. So please don't edit here, edit the extension's page. If you would like something to be changed about the content or format of the matrix, please put your suggestion on the talk page.
