Backdrop CMS
Lightweight PHP content management system for building websites

Backdrop CMS is a full-featured content management system (CMS) that helps non-technical users create, publish, and manage website content. It is a fork of Drupal that emphasizes a simpler architecture, fast learning curve, and solid out-of-the-box functionality.
Key Features
- Admin UI for creating and organizing content without programming
- Extensible functionality via add-ons (modules/themes) installable from the site
- Built-in upgrade path from Drupal 7 for easier migrations
- Performance-oriented design suitable for shared hosting environments
- Developer-friendly APIs and a codebase designed to be learned quickly
Use Cases
- Company or organization websites and intranets
- Blogs and content-driven marketing sites
- Community sites such as simple social networks or image galleries
Limitations and Considerations
- Primarily targets MySQL/MariaDB deployments; other databases are not a typical focus
- Ecosystem is smaller than Drupal’s, so specific niche modules may require custom development
Backdrop CMS is a practical option for teams that want a traditional PHP CMS with a straightforward development model and strong usability for content editors. It is especially relevant for Drupal 7 users seeking a familiar, lower-complexity path forward while retaining extensibility.
