Concrete CMS

Concrete CMS is an open source content management system for creating websites. It is built for people who want to manage pages and site content without working directly in code all the time.

It uses in-context, point and click editing, so editors update pages directly on the rendered site rather than in a separate admin form. The core ships with a wide set of built-in features, and a marketplace of add-ons and themes extends a site when more is needed.

Concrete CMS is an extendable platform built for both developers and editors, with role-based permissions and version history on page content. The 9.x line is the current release, with concrete5 8.x and 5.7.x kept as legacy versions. It is free open source software that you install and run on your own server.
