SilverStripe is a free and open source content management system (CMS) for creating and maintaining websites. The CMS provides a web-based administration panel that enables users to make modifications to parts of the website. This panel includes a WYSIWYG website editor. It is an open source web content management system used by governments, businesses, and non-profit organisations around the world. It is a power tool for professional web development teams, and web content authors rave about how easy it is to use.

As a platform, SilverStripe CMS is used to build websites, intranets, and web applications. The modern architecture of SilverStripe CMS allows organisations to keep pace with innovation on the web. SilverStripe CMS enables websites and applications to contain stunning design, great content, and compelling interactive and social functions.

Besides a powerful and intuitive content authoring application, SilverStripe CMS contains a powerful PHP5-based programming framework, Sapphire. Sapphire brings immense flexibility and ease in customising your site and provides fundamentals such as security models, workflow, caching, and multiple language and subsite support.

SilverStripe CMS is easy for both developers and content authors to work with. The Sapphire framework keeps the code tucked away neatly so that it can be accessed easily by programmers but does not get in the way of content authors.
