TypeContent Management System

concrete5 is an open-source content management system (CMS) for publishing content on the World Wide Web and intranets.[2][3]

concrete5 is designed for ease of use, for users with a minimum of technical skills. It enables users to edit site content directly from the page.[4][5][6][7][8] It provides version management for every page,[9] similar to wiki software, another type of web site development software. concrete5 allows users to edit images through an embedded editor on the page.[10]


concrete5 code is based on Model-View-Controller architecture[11] and object-oriented programming. Some core features are: integrated server caching, developer API, version tracking system and search engine optimization.


The concrete5 inline content editing GUI

concrete5 features in-context editing (the ability to edit website content directly on the page, rather than in an administrative interface or using web editor software). Editable areas are defined in concrete5 templates which allow editors to insert blocks of content. These can contain simple content (text and images) or have more complex functionality, for example image slideshows, comments systems, lists of files, and maps. Other addons can be installed from the concrete5 Marketplace to extend the range of blocks available for insertion. Websites running concrete5 can be connected to the concrete5 website, allowing automatic upgrading of the core software and of any addons downloaded or purchased from the Marketplace.


concrete5 is free and open-source (FOSS) under the MIT software license.


Development of concrete5 began in 2003 as a rapid-design approach to building the now-defunct, the official site for the Ad Council's National Council for the Lewis & Clark Bicentennial.[12]

The version 7 release of concrete5 was an incompatible with prior versions. All prior versions became known as the legacy branch, with the final version being before reaching end of life status on 24 August 2019.[13] Modern concrete5 (version 7 and above) features a new user interface, a user-accessible data model called Express, an extensive permissions model, and in-context WYSIWYG editing.[14]

Regular updates and security patches have been released.
