Concrete CMS
Concrete CMS (formerly Concrete5) is an open-source content management system built around a uniquely friendly idea: edit your content exactly where it appears on the page. Editors click on text and change it in place, with no dashboard detours, making it one of the most approachable powerful CMSs for less technical teams.
Key Features
- In-context editing — click any text or block on the live page to edit it in place; no back-end editing screens required.
- Drag-and-drop page builder — add and rearrange content blocks visually with a simple interface.
- Granular permissions — control access at the page, area, and block level with fine-grained roles.
- Multilingual support — manage multiple languages and regional content from one install.
- Workflow approvals — route page and content changes through an approval process before they go live.
- Built-in SEO tools — sitemaps, metadata, and clean URLs to help search engines find your content.
- Private file management — store and serve protected files with proper access control.
- Extensible marketplace — add-ons and themes extend the platform as your needs grow.
Why Use Concrete CMS?
Concrete CMS is the right choice when your team wants to manage their own website without learning a complex editorial interface. The in-context editing dramatically lowers the learning curve while the underlying platform stays powerful and flexible enough for developers and agencies.
Use Cases
- Organisations where non-technical staff maintain their own site content
- Agencies delivering client-editable sites quickly
- Corporate sites with formal page-approval workflows
