The Zope 2 web application platform has been under continuous development as an open source system since 1998. A large amount of software has been built on top of it. Well-known Zope-based projects are the Plone and Silva content management systems, and the ERP5 enterprise resource planning software.


The CMF (Content Management Framework) is a set of components built on top of Zope 2 to aid in the creation of content management systems. A well-known large content management system that has been built with the CMF is Plone.

Zope 3

Zope 3 is the next generation web platform developed by the Zope community. It has been under development since 2001, and became ready for production in 2005. Zope 3 is a developer-oriented platform. It aims to provide a collection of fine-grained components that can be combined to build powerful web applications.

Zope 3 can be used as an independent server platform, but can also be used in combination with Zope 2, using the Five integration layer.
