Concrete CMS

Concrete CMS (formerly concrete5) is an open-source content management system emphasizing in-context editing and user-friendly content management. It allows content editors to modify pages directly on the frontend using a visual editing interface, reducing the learning curve for non-technical users. Concrete CMS provides a block-based page building system where content elements like text, images, forms, and custom functionality are added as editable blocks. The CMS includes version control with page draft and approval workflows, making it suitable for organizations with content governance requirements. Concrete CMS offers fine-grained user permissions, multi-language support, and a marketplace with themes and add-ons extending core functionality. It is built with PHP and MySQL, providing developers with a framework for custom applications and integrations. Concrete CMS is commonly used by corporations, educational institutions, and organizations requiring user-friendly content editing with enterprise-level features.
