CMSD

CMSd is an open‑source, PHP‑based content management system designed for multi‑tenant web applications. It was created to provide a lightweight, extensible platform that allows multiple independent sites to share a single code base while keeping data isolated by database and configuration. The system supports a modular architecture, enabling developers to add or replace features through plug‑ins and custom modules without altering the core code.

The core of CMSd consists of a simple administration interface, role‑based permissions, and a basic page editor. It includes built‑in support for managing static pages, blog posts, image galleries, and forms. Advanced features can be added through a growing ecosystem of community plug‑ins, such as SEO optimization tools, ecommerce extensions, and multilingual support. CMSd stores each tenant’s content in separate database tables, which facilitates backup, migration, and scaling operations.

CMSd has a permissive MIT license, encouraging reuse in both commercial and non‑commercial projects. The development community is distributed, with contributions tracked on GitHub. Project milestones include regular releases that focus on security updates, PHP compatibility improvements, and minor feature additions. The documentation is organized into a web‑based manual, API references, and developer tutorials, making it accessible for newcomers and experienced programmers alike.

In practice, CMSd is well suited for hosting providers, agencies, and educational institutions that need to manage multiple client websites or campus portals from a single administration console. Its emphasis on a simple out‑of‑the‑box experience, combined with the flexibility of plug‑ins and a permissive license, has made CMSd a niche choice among PHP content management systems.
