Overview
Silverstripe CMS is an open-source content management system built on a PHP framework. It combines an administrative editing interface with structured data modelling and developer APIs.
The platform supports traditional websites and headless or decoupled delivery. Developers can expose content through REST-style endpoints or GraphQL, while editors manage content through the browser-based CMS.
Silverstripe CMS is installed with Composer and runs on a web server. Current documentation identifies PHP 8.3, 8.4, or 8.5 as supported requirements, with Apache and MySQL or MariaDB among common deployment choices.
