The t3versions bot is a friendly web crawler, which searches the internet for websites running the open source content management system TYPO3 CMS. You can identify the bot by the user agent string:
Mozilla/5.0 (compatible; t3versionsBot/1.0; +https://www.t3versions.com/bot)
The t3versions bot will save the domain name of a website to a database, if the website has been identified to use TYPO3 CMS. The domain name is saved for further TYPO3 CMS version analysis. Collected data is aggregated for statistical purposes only and publicly available at https://www.t3versions.com/statistics.
