Extensions

Extensions customize the functionality of MediaWiki, the software our wikis use. Like downloadable content for video games, extensions can enhance certain features of the wiki experience. Extensions are installed on a per-wiki basis and apply to all users on the wiki; depending on the extension, some users may not see its effects if they are logged out or do not have the relevant permissions.
Thousands of extensions are available for MediaWiki, many of which are now unmaintained. This page documents the extensions that wiki.gg keeps track of, split into four categories:
- Installed by default — these extensions are already installed on every wiki on wiki.gg!
- Available on request — wiki admins can request these extensions to be installed on their wiki, no questions asked
- Available on request with approval — wiki admins can request these extensions, but we will discuss the use case because they may have performance impacts, better alternatives, etc.
- Unavailable — these extensions are unmaintained, incompatible with wiki.gg, or have major issues regarding code quality, stability, etc.
If you would like to request an extension that is not in one of these four categories, send a request and we will evaluate the extension.
Existing wikis on other MediaWiki platforms that choose to fork to wiki.gg will have certain existing extensions installed on wiki.gg as well.
How to request an extension
If you are a wiki admin, you can request an extension to be installed or uninstalled on your wiki by following these steps:
- Make sure that the extension you want to install isn't already installed, or the extension you want to uninstall is actually installed. You can check this by going to Special:Version on your wiki and looking in the "Installed extensions" section.
- If you are requesting an extension to be installed, make sure it's not listed as unavailable below.
- Click here to fill out the extension request form. wiki.gg staff will review your request and respond accordingly.
If your request is approved, depending on the extension, you may need to adjust the extension's CSS styling to match your wiki style.
