This is a list of most 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.

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.


  • Requesting new extensions: If you would like to request a new extension, please create a task on Phorge. 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 vulnerabilities that would expose either Miraheze as a whole and/or individual users of the extension to security and/or privacy risks.
  • 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 either Miraheze 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.
