What Silverstripe CMS is

Silverstripe CMS is a content management system for websites, intranets, and custom web applications. Content managers can update pages without knowing HTML, arrange them in a hierarchy, move pages, and upload files by drag and drop. Authors can assemble pages from content blocks and choose their structure. Roles and permissions can support review and approval workflows, while content versions can be reviewed or reverted. The CMS supports multilingual authors and visitors, including languages that use Unicode, such as Chinese and Arabic. It includes a media library and supports custom content types. Modules and themes extend the system, with modules listed through Packagist and ssmods.com. API integration points, multi-server cloud configurations, and a GraphQL content API layer are supported. Silverstripe says the CMS is professionally maintained and has built-in security features, with security releases for supported modules. Developer resources include documentation, forums, Slack, Stack Overflow, and a directory of support options. The maker recommends developer-led installation using Composer and advises checking server requirements and configuring an environment and database. The open-source BSD license has no licensing fee: the listed price is free.
