TYPOlight

TYPOlight is an open-source content management system (CMS) designed for building and maintaining websites. It was originally released in the mid-2000s by Austrian developer Leo Feyer. The system was noted for its lightweight, fast backend and a modular approach that allowed site pages to be composed from discrete content elements and modules. Pages were rendered through templates, and the CMS offered features intended to streamline everyday web publishing.

Key design goals of TYPOlight included usability for non-technical editors, accessible administration, and a flexible architecture that could be extended through add-ons. It supported multi-language websites, user and permission management, and a suite of built-in modules and content elements to handle common site functions such as news, calendars, forms, and other interactive components. The combination of a clear backend interface and a template-driven front end contributed to its appeal for small and medium-sized organizations.

In 2009–2010, due to trademark considerations, the project was renamed Contao. Development continued under the Contao name, with ongoing releases that modernized the codebase and expanded capabilities while preserving the concepts and workflow introduced by TYPOlight. Today, the TYPOlight project is regarded as the predecessor to Contao, with historical documentation and community discussions reflecting its origins.
