Silverstripe

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.

Silverstripe provides page and content management, media administration, configurable data objects, templates, permissions, and extensibility through modules.

Its supported module ecosystem includes asset management, versioning, reports, campaign administration, multilingual content, user forms, workflow, spam protection, GraphQL, and database integrations.

The framework includes extension hooks, dependency injection support, configuration APIs, custom templates, and Composer-managed dependencies. These features support bespoke websites and web applications rather than only fixed template-based publishing.

The Silverstripe CMS software is available as a free, open-source download under a BSD license. The official download process uses Composer and requires a developer or technical team to configure the server and database.

Silverstripe Ltd also provides commercial services, supported modules, managed hosting, and project assistance. Public fixed prices for those services were not identified, so costs require a direct quotation.

Pros: Open-source licensing keeps the core software accessible. The framework supports detailed customization and structured data models. REST and GraphQL options support headless delivery. Commercially supported modules receive maintenance and security coverage.

Cons: Installation and customization generally require PHP and web development knowledge. Many advanced capabilities depend on modules or bespoke development. Independent reviews indicate a smaller market presence and fewer ready-made themes than larger CMS platforms.

WordPress is a broader general-purpose CMS with a larger plugin and theme marketplace. Drupal provides another open-source, highly configurable platform for complex content structures and permissions.

Umbraco is a comparable developer-oriented CMS built on the Microsoft .NET ecosystem. Wagtail offers an open-source Django-based CMS, while Strapi focuses on API-first headless content management.

Is Silverstripe free? Yes. Silverstripe CMS is open-source software distributed under a BSD license. Hosting, implementation, support, and commercial services may cost extra.

Does Silverstripe have an API? Yes. The platform supports REST-style integrations and has a supported GraphQL module. Developers can also create custom JSON endpoints and integrate external services.

What platforms does Silverstripe support? Silverstripe CMS runs on web servers using PHP. Current documentation lists PHP 8.3 through 8.5 and commonly references Apache with MySQL or MariaDB.

Does Silverstripe offer a free trial? No separate time-limited trial was identified. The open-source CMS can be downloaded and installed for evaluation, subject to the required server environment.

Who is Silverstripe best for? It is best suited to organizations and agencies needing structured content, custom workflows, bespoke integrations, or developer-controlled website architecture.
