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 some of those extensions which have been requested but cannot be installed, and a brief reason as to why.

Installed Extensions

Global Extensions

Some extensions are enabled by default 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 used on Meta. The extension is enabled globally due to technical reasons as ManageWiki requires this extension and wikis will break if it is not enabled.
CookieWarning – Required for legal/privacy reasons
ConfirmEdit – Important anti-spam tool, generates a CAPTCHA to prevent unauthorized automated actions
Echo – This extension implements the user notification system
EventLogging – Required dependency for CentralNotice
GlobalBlocking – Important anti-spam and anti-vandalism extension, allows Miraheze Staff to block IP addresses that vandalize multiple wikis
GlobalCssJS – Part of the global account system, allows users to have custom interface styling applied to all wikis
GlobalPreferences – Part of the global account system, allows users to have default preferences (settings) on all wikis
IncidentReporting – Used internally by Miraheze system administrators for reporting incidents such as downtime. Installed globally but only has a function on Meta
Interwiki – Used to provide direct links from one Miraheze Wiki to another, and to other MediaWiki sites (such as these links to MediaWiki.org)
LocalisationUpdate – Essential/core part of MediaWiki interface
LoginNotify – Important security feature, notifies users about suspicious attempts to login to their accounts
ManageWiki – The extension used for managing wiki settings, including extensions. Turning this off would remove the ability to enable/disable other extensions
MatomoAnalytics – Internal Miraheze extension
Nuke – Important anti-vandalism extension, allows site administrators to mass delete multiple pages at once
OAuth – Internal Miraheze extension, used for linking wiki accounts with accounts for Miraheze Phabricator
OATHAuth – Important security feature, used for implementing 2-factor authentication
ParserFunctions – Essential/core part of MediaWiki interface
ParsoidBatchAPI – Required dependency for VisualEditor and Flow
RenameUser – Implements the ability for Miraheze Staff to rename user accounts on request (otherwise this would be impossible)
RottenLinks – Internal Miraheze extension that checks for dead or broken external links on wiki pages
Scribunto – Essential/core part of MediaWiki interface
SpamBlacklist – Important anti-spam feature, allows administrators to blacklist spam websites from being mentioned
SyntaxHighlight – Essential/core part of MediaWiki interface
TitleBlacklist – Important anti-vandalism extension, allows administrators to prevent pages with certain titles and certain usernames from being created
TorBlock – Important anti-vandalism and anti-spam extension, prevents vandals from using TOR to rapidly change IP addresses
UserMerge – Allows Miraheze Staff to merge contributions of one user account into another. Not used frequently but is used for various maintenance purposes
WikiDiscover – Internal Miraheze extension that shows all Miraheze wikis with some general information about them
WikiEditor – Essential/core part of MediaWiki interface

Default Extensions

These extensions are enabled by default on all new wikis but can be disabled in Special:ManageWiki/extensions:

CategoryTree – Popular extension used by multiple wikis
Cite & CiteThisPage – Important and popular extension used for generating citations for wiki pages
DarkMode – Enables a dark user interface. Used for accessibility reasons and for personal preferences
GlobalUserPage – Allows users to display the content from their userpage on Miraheze Login Wiki on all wikis if they have not created a local userpage
MobileFrontend – Important MediaWiki feature for wikis that wish to support editing from mobile devices (which is the vast majority of wikis)

Other Extensions

These extensions are installed on Miraheze and can be enabled in Special:ManageWiki/extensions on any wiki but are not enabled by default:

Declined extensions

Many extensions have been requested but are not able to be installed for various reasons. The most common reasons are that the extension introduces security and/or privacy risks that cannot be mitigated, that the extension is not being actively maintained upstream, or that the extension conflicts with a global extension that cannot be removed. The following is a list of declined extensions, and a brief reason why they are declined.

AccessControl – Doesn't work on MediaWiki 1.29+, and also has privacy issues
BlueSpice – Security risk
Configure – No longer maintained upstream (hasn't worked since MediaWiki 1.18), and ManageWiki essentially does the same thing
ConfirmAccount – incompatible with CentralAuth - since user accounts exist globally it is not possible to have individual wikis require accounts be approved
DeleteBatch – Technical limitations, see T956
DNSlookup – Invades user privacy
EditAccount – Incompatible with CentralAuth - since user accounts are global, editing a user's information on one wiki would affect all wikis. Also allowing other users to change email addresses and passwords is a major privacy and security risk
EditUser – Same reasons at EditAccount
EmbedAnything – Security risk
EmbedVideo – Security risk
External Data – Security risk (SQL injection)
ExternalLinks – Security risk, see T1555
Html2Wiki - Unreadable code, see T2740
Html5mediator – Declinado por problemas de seguridad (inserción arbitraria de JS), T1640.
Markdown – Not actively maintained upstream
MiniInvite – Security risk
MultiUpload – Not maintained upstream** - You can use MsUpload which provides similar functionality
OpenID Connect – Security risk
Page Schemas - Unmaintained, likely requires Semantic MediaWiki, which is also declined (See the relevant task)
PluggableAuth – Security risk
SecurePoll – Reveals private information
Semantic MediaWiki – Miraheze does not currently have the resources to support SMW. You can use Cargo instead.
Semantic Text Annotator – Requires Semantic MediaWiki
Site settings – ManageWiki does the same thing (actually even more), and up until recently had a major security flaw
Tasks Extension – Flagged as unstable, indicating one or more parts, or even the entire extension, is broken
UploadWizard – Extension is too specific for Wikimedia. Unsuitable for independent wikis to be using it. See T288.
UserGroups – ManageWikiPermissions does the same thing.
Widgets – See 23-12-2020 Security Disclosure
WikiBanner – We don't accept ads
Extensions made by Fandom that do not have independent on mediawiki.org – extensions such as Special:Withoutimages, MediaWiki:ImportJS, and Special:AdminDashboard are too specific for Fandom. Use similar extensions instead.

Disclaimers

Requesting new extensions: If you would like to request a new extension, please create a task on Phabricator. Please be aware that any extensions which are not in use by one or more Wikimedia Foundation projects will require a security review before being installed. The purpose of this review is to check the code to make sure there are no vulnurabilities that would expose either Miraheze as a whole and/or individual users of the extension to security and/or privacy risks. Unfortunately, this review process is severely backlogged, and therefore extension reviews can take several weeks to in some cases several months.

Restricted extensions: Some extensions in the list of globally enabled extensions are restricted and cannot be used by individual wikis and users, and can be used exclusively by members of the Miraheze Staff team - either Stewards and/or System administrators. This is usually for either or both of the following reasons: the extension reveals private information that under most circumstances should not be accessed, but may need to be accessed in order to stop spam and vandalism; and/or the extension has effects on the overall operation of Miraheze and therefore use of the extension outside of Meta Wiki would break things.

Note about MultiUpload: This extension is no longer being actively maintained upstream and therefore is unsuitable for Miraheze. However, users who are familiar with another wiki hosting service, ShoutWiki, may be aware that the extension in use there. The extension is only being maintained as a local copy by ShoutWiki developers for their specific service, and even these developers have indicated that they will not continue to maintain it if it ultimately breaks down. Therefore, please use MsUpload instead, which provides similar functionality.
