Fandom

Wikia is is a selective free web hosting service that uses a fork of MediaWiki as its hosting engine and is known for its wide variety of MediaWiki extensions. See Wikia's website or the English Wikipedia article on Wikia to find out more about Wikia in general.

Extensions
Some of Wikia's extensions can be found at Wikimedia's official SVN repository and their appropriate extension pages are located at Category:Extensions by Wikia, Inc..

Other extensions are still located in Wikia's own SVN repository, in the folder /releases/[release number here]/extensions/wikia/. It is likely that most of the extensions have dependency on the EasyTemplate class (found at /releases/[release number here]/includes/wikia/ folder on Wikia's SVN) and/or they might require custom database tables. Source code comments are not as common as in the official MediaWiki either.

Wikia's SVN
Wikia's SVN repository can be accessed at svn.wikia-code.com. Please note that it is an entirely separate repository from Wikimedia's official Subversion repository and is not affiliated with the official SVN (svn.wikimedia.org). You can browse the repository by using the Trac browser.
