About concrete5

Concrete5 is an open source content management system for publishing on websites and intranets. It is now presented as Concrete CMS. Editors change content directly on the page, so people with little technical skill can maintain a site.

Main features

  • On-page editing: content edited in place, with a short learning time for new editors.
  • Permissions: roles and groups that control access down to individual blocks of text.
  • Workflows and versions: approval workflows, change logs, and version comparison and rollback.
  • Marketplace add-ons: extra features for navigation, images and more.
  • AI tooling: Atlas and an MCP server, both open source, built by an outside developer.
  • Hosting: hosted plans including Starter, Business and a custom service-level option.

Who it serves

Content creators, designers and developers, as well as organisations with strict security needs.

Key facts

  • Security: ISO 27001 certified, with SOC 2 and HIPAA compliant hosting
  • Customers: the site names the U.S. Army as a user
