Meta Generator Version Check is a free Chrome add-on developed by White Fir Design. This add-on is designed to alert users if a web page is generated from an outdated version of popular web software such as WordPress, Joomla, MediaWiki, and more.

The add-on works by checking the meta generator tag on web pages to determine if the software used to generate the page is outdated. It currently includes checks for various versions of WordPress, Joomla, MediaWiki, vBulletin, TYPO3, concrete5, SPIP, Exponent CMS, Zinnia, Revive Adserver, and WooFramework.

If a user notices that a software version is missing from the add-on's checks, they can contact the developer to request its inclusion.

For users who manage multiple websites, White Fir Design also offers the "Up to Date?" Chrome app, which allows users to track the versions of concrete5, Joomla, MediaWiki, Revive Adserver, SPIP, TYPO3, and WordPress running on their websites.

Stay up to date with your web software and ensure your websites are secure with Meta Generator Version Check and the "Up to Date?" Chrome app.
