The WhosOnline extension adds a special page, Special:WhosOnline, which shows the list of all users (optionally including anonymous users) currently viewing the wiki. It creates this list by finding all users who last viewed any page on the wiki less than the time ago specified by the setting $wgWhosOnlineTimeout, which by default is one hour.


  • Download and move the extracted WhosOnline 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/WhosOnline
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'WhosOnline' );
    $wgWhosOnlineShowAnons = true;
    // If you want anonymous users IP addresses shown. Default is not to show them, for privacy reasons.
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


Users who login after the extension is installed can be seen at Special:WhosOnline. Refresh the page if it is blank. It is possible to transclude the contents of the special page into another page: {{:Special:WhosOnline}}. If you use {{:Special:WhosOnline/10/shownav}} it will only show 10 users and will have the navigation controls.
