TYPO3 is a web content management system (CMS) written in the programming language PHP. It is free and open-source software released under the GNU General Public License version 2.
TYPO3 is similar to other content management systems such as Drupal, Joomla!, and WordPress. It is used more widely in Europe than in other regions, with a larger market share in German-speaking countries, the Netherlands, and France.
TYPO3 was acknowledged as a Digital Public Good by the Digital Public Goods Alliance in April of 2025.
TYPO3 allows for the separate maintenance of code and content. It can be extended with new functions without writing any program code. TYPO3 supports publishing content in multiple languages due to its built-in localization system.
