papaya CMS is an open-source content management system, free of charge and complying with open standards like XML as data format, XSLT as templating language, and PHP for programming.


Development started in 2000 as a commercial project, papaya CMS was then released as an open-source CMS under the GNU General Public License in 2005. Its architecture and feature set are derived from the initial use case in commercial/larger installations.

System architecture

papaya CMS is a software build upon a modular concept, to use it as framework for special applications beside the typical tasks of a content management system. It fully supports unicode, multi-language and multi-site installations.

All texts, configuration data etc. is stored as XML in a relational database. Media files such as images and videos are located in the file system and will be managed by papaya and referenced as needed.

Many functions (such as database access, authentication, build methods for backend menus, etc.) are defined centrally and can be accessed through an abstraction layer.

papaya CMS is developed in PHP and object-oriented. Data is stored in XML, XSLT is used as template language. The system does not use self-developed or proprietary script- or templating languages.

Special features

Unlike many other CMS papaya CMS is characterized by the fact that it is available under the GPL on the one side. On the other side, a company behind the product is available that provides support and training.


With its clear separation of content, layout and formatting using XSL/XSLT, anything possible in XHTML/HTML can be implemented in papaya CMS - this is in the hands of the developer. So papaya is an option for accessibility.
