The VersionCompare extension displays a special page, Special:VersionCompare, that compares the MediaWiki, PHP, database, and extension versions of two wikis. It provides two text fields to enter the API URLs of the two wikis to compare. If one of the text fields is left blank, the local wiki will be used as one of the two wikis.


  • Download and move the extracted VersionCompare folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/VersionCompare
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'VersionCompare' );
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
