Extensions

This is a list of all extensions installed on Miraheze, sorted by three categories: global extensions that are enabled on every wiki that cannot be disabled (and a brief reason why), default extensions that are enabled on new wikis by default but can be disabled, and extensions that are not enabled by default but can be enabled on individual wikis. This page also includes those extensions which have been requested but cannot be installed, and a brief reason as to why.

Global Extensions
Some extensions are enabled by default globally across all Miraheze Wikis and cannot be disabled by local wikis. These extensions are listed below, with a brief reason as to why they are global.


 * AbuseFilter – Important anti-spam and anti-vandalism extension
 * AntiSpoof – Prevents impersonation user accounts from being created
 * BetaFeatures – Beta Features are installed globally but can be turned off in one's individual user preferences
 * CentralAuth – Defines the global user account system, without it user accounts would break
 * CentralNotice – Used for distribution of important notices about Miraheze, such as planned downtime
 * CheckUser – Important anti-vandalism extension that allows Miraheze Staff to block the underlying IP ranges of vandalism accounts
 * CreateWiki – This is how new wikis are created (perhaps the most important extension!). Installed globally but only has a function on Meta
 * CookieWarning – Required for legal/privacy reasons
 * ConfirmEdit – Important anti-spam tool, generates a CAPTCHA to prevent unauthorized automated actions

<!--=== Declined extensions (<1.31) === Those extensions which are not available and a brief reason.
 * AccessControl – doesn’t work on MediaWiki 1.29+, and also has privacy issues
 * BlueSpice – security risk
 * Configure – ManageWiki does the same thing, and the extension doesn’t work with latest versions of MediaWiki
 * ConfirmAccount – incompatible with CentralAuth
 * DeleteBatch – because of technical limitations, see T956
 * DNSlookup – invades user privacy
 * DynamicPageList – flagged as unmaintained
 * EditAccount – incompatible with CentralAuth
 * EditUser – incompatible with CentralAuth and also flagged as unstable. Similar reasons to EditAccount.
 * EmbedAnything – security risk
 * EmbedVideo – security risk
 * External Data – security risk (SQL injection)
 * ExternalLinks – security risk, see T1555
 * Html2Wiki - unreadable code, see T2740
 * Html5mediator – declined due to security issues (arbitrary JS insertion), T1640. Use Widget:Html5media instead.
 * Markdown – flagged as unmaintained
 * MiniInvite – security risk
 * MultiUpload – flagged as unmaintained, instead use MsUpload
 * SecurePoll – reveals private information
 * Semantic MediaWiki – alters MediaWiki too much, use Cargo instead
 * Semantic Text Annotator – requires Semantic MediaWiki
 * Site settings – ManageWiki does the same thing
 * Tasks Extension – flagged as unstable
 * UploadWizard – Extension is too specific for Wikimedia. Unsuitable for independent wikis to be using it.
 * UserGroups – ManageWikiPermissions does the same thing.
 * UserMerge – incompatible with CentralAuth
 * WikiBanner – we don't accept ads
 * Extensions made by Wikia that do have pages on mediawiki.org – extensions such as Special:Withoutimages, MediaWiki:ImportJS, and Special:AdminDashboard are too specific for Wikia. Use similar extensions instead.

Disclaimer

 * Extensions not used by Miraheze or Wikimedia Foundation (a organization we trust to do rigorous security review) must pass security review by our volunteers. It may take long time to process.
 * Some extensions enabled by default cannot be disabled by local wikis or communities, nor can some extensions be used or managed by local wiki bureaucrats or administrators. Extensions in the first list that have a * next to them indicate that either they are required and cannot be disabled, and/or they cannot be used except by global Miraheze staff members. For example, CentralAuth is required, otherwise parts of Miraheze may break. CheckUser, GlobalBlocking, and RenameUser cannot be used except by Miraheze staff.
