For the basics on how to install extensions on your wiki, please see the knowledgebase article called Adding extensions or skins onto your wiki.
This is not an exhaustive list. Contact support for more information on whether we support an extension or not.

This is not an exhaustive list either; there may be more extensions we don't support. We only add extensions to this list if there is a compelling reason to not support it. In other words, we try our hardest to avoid placing extensions on this list. Our support team will make the final feasibility determination.
|Extension name||Reason we don't support it||Suggested alternative(s)|
|CheckUser||Due to our GDPR and data privacy compliance procedures, we are unfortunately unable to offer this to wiki owners, as doing so would violate EU laws. MyWikis Staff will use this extension when deemed necessary. Contact our support team for more details.||AbuseFilter, Nuke|
|Math, MathJax||Too complicated—we use SimpleMathJax, which provides the exact same functionality.||SimpleMathJax|
|CentralAuth||Does not apply to non-VPS wikis. Some VPS wikis may be able to use this, if appropriate.|
|Citoid||Requires additional processes to run on servers. Permitted on our VPS plans.|
|Farmer, Wiki Farm, etc.||We do not allow extensions that can create other wikis.|
|GoogleLogin||We support it but be careful because you might actually need SAML for logging in via a Google Workspace account. Permitted on Gen2 or our VPS plans if database is MySQL.|
|MsUpload||Extension doesn't work and has many severe security bugs on MediaWiki 1.27+. We recommend using SimpleBatchUpload or UploadWizard instead.||SimpleBatchUpload, UploadWizard|
|Google Analytics Integration||Newer extension, called GTag, supports the newer Google Analytics tags.||GTag|
