Seditio CMS

Seditio is a powerful, fast, and flexible Content Management System (CMS) and Content Management Framework (CMF) powered by PHP and MySQL.

The key distinguishing feature of Seditio is the complete separation of HTML design and layout from PHP business logic, achieved using the XTemplate SE template engine. This enables web designers and front-end developers to craft rich themes and skins without requiring deep PHP knowledge.
