SilverStripe administrator interface version 4.0
4.2.1 / July 31, 2018
|Type||Content management system|
SilverStripe is a free and open source Content Management System (CMS) and Framework for creating and maintaining websites and web applications. It provides an out of the box web-based administration panel that enables users to make modifications to parts of the website, which includes a WYSIWYG website editor. The core of the software is SilverStripe Framework, a PHP Web application framework.
SilverStripe is released under the terms of the BSD License.
SilverStripe separates the roles of:
- content authors (who get a rich (AJAX) web-based user interface that omits technical jargon); and
This contrasts with CMS products which allow technical website development tasks to be performed within a GUI, and also contrasts with programming frameworks which offer no out-of-the-box content authoring application. The SilverStripe approach allegedly removes complexity for content authors, and offers more flexibility to developers.
The core of SilverStripe is named SilverStripe Framework. As with the rest of the platform, it is written in PHP (5.3), and takes advantage of its object-oriented design capabilities such as name-spacing. The SilverStripe framework (formerly referred to as "Sapphire") provides website developers a framework to build and extend websites based on modern programming techniques including the model-view-controller (MVC like, the model doesn't include the ability to notify the view of updates) pattern and object-relational mapper.
SilverStripe generates markup using a custom template-language based on W3C HTML5 that offers simple placeholders and conditional logic. SilverStripe is extensible through modules, widgets, themes and code customization.
Notable features of the SilverStripe CMS include:
- Out of the box template, supporting responsive design (works on smartphones, tablets, and desktop computers)
- An extensible web application interface
- Rich-text editing based on a modified version of TinyMCE
- Quick embedding of videos and other resources from websites like YouTube, slideshare, etc. (using oEmbed)
- Drag-and-drop tree-based navigation structure
- Custom output markup and table-free default styles (including HTML5 and mobile support)
- Work-flow management: Draft/Published separation through content staging, document revision control/rollback with 'compare' functionality
- Configurable security/permissions model (role-based)
- Data object model, database generation through object-relational mapping, suite of customizable data input controls.
- asset management, image resizing, drag&drop images from OS desktop to upload.
- Multiple templates per page
- Search engine friendly URLs, metadata management, XML site map generation
- Full text search and RSS feeds
- Optimizations for heavy loads (full and part-template caching)
- Internationalization/Languages: SilverStripe supports multiple-language content. UTF-8 and the internationalization of character sets are supported. The CMS is available in many languages, including English, French, German, Spanish, and Chinese.
- Hierarchical URLs
- Cross-platform: OS (Linux, Windows, Mac), Web server (Apache, IIS), Database (MySQL, PostgreSQL, Microsoft SQL Server fully supported; SQLite and Oracle Database have limited support.)
Notable features of upcoming releases of SilverStripe include:
- Additional administration UI (e.g. web-interface based installation of modules, widgets)
- Site-wide widgets
Common CMS features not currently available in SilverStripe include:
- In-place page editing
- Web interface based installation of modules, widgets or themes
- Web interface based customization of themes
- Automated cache management/ORM refresh
Modules, widgets, and themes
Modules extend the core functionality of SilverStripe. Some existing modules include: Blog, Advanced Workflow Management, eCommerce, Forum, LDAP/OpenID authentication. Modules are available from the SilverStripe modules repository, which as of January 2016, lists over 1400 modules.
SilverStripe Widgets are small pieces of functionality that can be drag-and-dropped into SilverStripe modules (notably the blog module). Examples of widgets include: tag clouds, Flickr photos, or word of the day, although widgets are a relatively less-used aspect of the platform. As of August 2012, there are 96 widgets.
The SilverStripe themes directory provides a number of community-contributed, freely available themes (84 as of August 2012).
Modules, widgets, and themes are all available as free downloads under the BSD license, and the majority of them are community contributed.
- Apache v1.3.19+, Lighttpd, Hiawatha, Cherokee, or Microsoft IIS 7.x+ (A URL Rewriter is required. As of 2.4.0 IIS 7 URL rewriting is supported out of the box)
- MySQL v5.0.X+, Microsoft SQL Server 2008+, PostgreSQL 8.3+, SQLite3 (community maintained) and Oracle Database (experimental)
- PHP 5.3.3+ with MySQL, GD Graphics Library and zlib support
SilverStripe is released under the terms of the BSD License. Documentation is available for CMS users and website developers. An online demonstration of the CMS is available as an interactive demo. Two technical reference books on SilverStripe are available in English and one in German.
The SilverStripe software is developed by SilverStripe Limited, a website development company founded in 2000.
Prior to SilverStripe 2.x, the CMS was commercially available under a proprietary license. Development of SilverStripe 2.X started in late 2005, as a complete overhaul to take advantage of object orientation and new features in PHP5.
On 29 November 2007, SilverStripe announced they would be participating in the Google Highly Open Participation Contest. This led to a proliferation of themes, translations and widgets that broadened the system.
In late 2008, SilverStripe split its main website into silverstripe.com, to act as the home for the company behind the software, and silverstripe.org, to act as the home for the software and its open source community.
In May 2009, the SilverStripe company formed partner associations with other website development companies to represent the company in foreign markets.
In February 2010, SilverStripe claimed the software had been downloaded 250,000 times since first released.
In November 2010, Microsoft blogged that SilverStripe CMS became the world's first open source web application to attain its 'Certified for Windows' status.
In June 2012, SilverStripe 3.0 CMS was released, containing significant usability and developer API changes; SilverStripe Framework was released for the first time as a stand-alone framework.
In October 2013, SilverStripe 3.1 CMS was released, with more visual feedback and easier preview, composer support, YAML configuration and an improved UploadField
In January 2015, SilverStripe software is downloaded for the 750,000th time since first release. 
In August 2015, SilverStripe Platform 1.0.0 is released with a new design and extra features. 
The first StripeGirls meetup is held in September 2015. StripeGirls are a group of women in Wellington who are interested in PHP and SilverStripe. 
In December 2015, with 94% revenue growth, SilverStripe again makes it on to the Deloitte Asia Pacific Technology Fast 500 Index (SilverStripe also appeared in 2008, 2009, 2010, and 2011). 
June 2016 sees the SilverStripe Platform become certifiable. HTTPS support becomes available for all SilverStripe Platform site sizes. 
In June 2018, there are 49,000 SilverStripe sites. A BuiltWith report shows there are tens of thousands of sites using SilverStripe.
