DNN is a free and open source Content Management System (CMS) based on the .NET Framework from Microsoft.

Like other CMS like Wordpress, Joomla or Drupal, DNN allows users to create and manage online content. And like other CMSs, you will be able to extend the application with customizable add-ons to suit your needs.

However, unlike most other CMS, it is built on .NET, which means it is built on a solid foundation created by the world's most successful technology company. DNN is by far the most successful open source CMS built on this enterprise grade infrastructure.

DNN is a tool that really lets you create whatever you want. It can be a stunning design project, a robust database, or a business-to-digital workflow application. DNN's possibilities are endless.
