Originally developed as a community platform for a student dorm, Drupal has become more of an application framework than just CMS, thanks to its large and active developer community. It fulfils the broadest range of requirements, combining flexibility, scalability, accessibility, and today’s latest web technologies. Drupal is the third most used CMS in the world.
TYPO3 has pragmatic, professional roots in the world of digital agencies. Its design and development direction has always been to enable digital agencies to serve their customers best. The community likes to call TYPO3 CMS “The Enterprise Content Management System” and it retains strong adoption in universities, government, and enterprises in central Europe among its 500,000+ reported installations. It is supported by a large agency- and service provider-base, especially in the “DACH” German-speaking region.
Plone is Python-based efficient and flexible high-performance Content Management System designed for professional use. It stands out especially because it features a secure and sophisticated access control management, quality assurance in content management, a workflow-controlled collaborative management of content, universal usability and powerful tools for system administration.
eZ Platform, based on the Symfony framework, replaces its predecessor eZ Publish. With eZ Platform developers have the capability to develop various types of content presentation while editors have the tools to create, deliver and optimize content. This offers companies the ability to deliver multisite, multichannel and multilingual websites and apps.
