Overview
REDAXO is a free, open-source PHP content management system developed since 1999 by the German agency Yakamara in Frankfurt am Main and released publicly as open source in 2004. It switched from the GNU GPL to the more permissive MIT license in 2016.
Development is community-driven, led by Yakamara's core team alongside Friends of REDAXO, a volunteer association of independent developers and agencies that contribute modules, translations, and core improvements.
Key Features
REDAXO centers on a modular content architecture where developers build custom modules and templates with full control over HTML, CSS, and PHP output, separating layout from content for non-technical editors. It supports fully multilingual websites and content trees, plus structured media and file management.
A granular, configurable user rights and role system lets administrators define exactly what each backend user can see and edit, and the backend interface itself is available in German, English, Spanish, Italian, Swedish, and Portuguese.
Pricing
REDAXO is entirely free and open source under the MIT license, with no pricing tiers, subscription plans, or paid editions of the core software.
The surrounding ecosystem is supported through community contributions and sponsorships, while independent web agencies that specialize in REDAXO separately offer paid implementation, customization, and hosting services.
