Content management system
From Wikipedia, the free encyclopedia
Contao (formerly TYPOlight) is a free content management system (CMS) for medium to large websites. The program specializes in back-office (i.e. for developers) and front-office (i.e., for users) accessibility, and observes XHTML, HTML5 and CSS standards, according to W3C/WAI guidelines, to generate pages. The program is an open-source project, published in its original form in 2006 by Leo Feyer and hosted on GitHub.

Features
The Contao content management system has built-in search engine, file manager and form builder tools and features automatic live updating. With its CSS framework and built-in jQuery and MooTools libraries, it readily supports multilingual content (UTF-8 character set) throughout), as well as for documentation and in the back-end administration area, uses Web 2.0 and Ajax techniques and offers version control and cancellation management (undo/redo), permitting a user to review and, if necessary, roll back changes to a prior state. Although the program makes use of a graphical interface, many program instructions require resorting to a command-line interface.[3] From the administration area, a user may choose to install, update or uninstall any of over 1,700 extensions or update the database.[4].
As of version 5.0, Contao requires a web server that routes requests to PHP, PHP version 8.1+, MySQL 5.7+ or an equivalent MariaDB version, and 11 PHP extensions. As of October 2025[update], Contao is compatible with and recommends using the latest version of PHP and MySQL/MariaDB.[5]
Name
At launch, Contao was named TYPOlight. To avoid confusion with TYPO3—another open-source CMS—[6]and the association of "light" with having a small number of features, it was renamed to Contao in 2010 with version 2.6.[7][8]
In his Contao book, Peter Müller offered his interpretation of the name: C, O, and N are the first letters of content, and tạo is a Vietnamese word that means 'to model, generate or shape'; together, the name represents how Contao "allows content to be generated, shaped and managed".[9]
Reception
In 2007 Packt Publishing named TYPOlight, as Contao was then known, the second-place winner in its "Most Promising Open-Source CMS" awards category.[10] In 2023, Pierre Edouard Laurent of Clubic gave Contao an 8 out of 10 for its light resource usage, simplicity, and features despite conceding its high entry barrier.[6]
As of November 2023[update], Contao is the sixth most widely used CMS int he world with 0.5% of the market share. It is mostly used in Germany and Switzerland.[6]
