Sitefinity is a Web Content Management System, which provides an open, extensible environment of visual construction and management of public sites, intra- and extranets.

Although it offers a highly usable 100% WYSIWYG environment for non-technical business users, Sitefinity is built with the developer in mind. It uses an open modular architecture and a fully-exposed API, which allows web-developers to modify out-of-the-box functionality, add new modules, and reuse available ASP.NET components from the comfort of Visual Studio® .Net.

Completely Browser-Based Application:
telerik Sitefinity is a completely browser-based application, which does not require downloads or installation of plug-ins, ActiveX controls, or Flash players. The content management capabilities of the application can be accessed from any computer with a supported browser.

100% WYSIWYG In-Context Site Management Environment:
Sitefinity is developed to transfer the process of web-site creation and content management entirely to the web. There are no preview buttons - your workspace is your staged web-site, so watch it grow. Thanks to the award-wining telerik r.a.d.designer component you will not have to select pages and content blocks from long lists and complex treeviews, but can rather use the site's own navigation system to browse and manage the information in its true context.
