Concrete CMS, formerly known as Concrete5, is an open-source content management system (CMS) designed to facilitate the creation, management, and publishing of web content. It is known for its ease of use, robust functionality, and strong security features, making it suitable for a wide range of applications from simple blogs to complex enterprise websites. The platform is particularly noted for its intuitive in-context editing, which allows users to make changes directly on the web page, and its comprehensive built-in features that reduce the need for third-party extensions.

The platform has grown from a small media shop project to a widely used CMS with a significant user base, including notable clients like the U.S. Army and BASF.
