The following extensions allow certain users to approve and unapprove either specific revisions of wiki pages and/or files, or entire wiki pages and files. This allows granting edition permissions to more contributors while lessening the effects of unwanted changes such as those from spammers and vandals.

• Approved Revs - Allows users to mark a certain revision of a page or file as the approved one, which is shown by default to users. A setting allows pages with no approved revision to be shown as blank.
  • Semantic Approved Revs - Allows the storage of data related to Approved Revs approvals via Semantic MediaWiki properties.
• ContentStabilization - Allows users to mark pages as "approved" or "draft" and to view the most recent approved version of a page.
• FlaggedRevs - Allows users to rate different page revisions, and to accept a new revision as the default shown to viewers. This extension is more advanced (flexible) than others and remains fairly maintained by the Wikimedia Foundation and in use on some Wikimedia sites, but is complex, immature and considered very clunky.
• Moderation - Edits and uploads from untrusted users are sent to a moderation queue, where they get approved or rejected. Edits that have not been approved do not appear in the edit history, and are invisible to users who are not moderators.
• Page Approvals - Entire pages, rather than specific revisions, are marked as either "approved" or "not approved". Approval is automatically revoked in the case of an untrusted edit or other content change, like a change to an embedded template.
