DotNetNuke is an open-source Web Application Framework ideal for creating and deploying projects such as commercial websites, corporate intranets and extranets, online publishing portals, and custom vertical applications.

The vision of the DotNetNuke project is to create an open source content management system (CMS) product – one which promotes human participation and the sharing of knowledge.
 

Features

Fully extensible and scalable.
Suitable for a variety of projects - from the smallest website to the largest corporate deployment.  Internet or Intranet sites can be developed entirely with built-in DotNetNuke features, or can be augmented through third-party private assembly tools.

Clearly licensed under a BSD-style license. 
Software can be completely incorporated, modified, and adapted to personal/business use without having to worry about legalities.

Constantly evolving through real world trial. 
Open source nature of  DotNetNuke allows programmers and webmasters to read, redistribute, and modify the source code, essentially evolving the software at a rapid pace.  End-user suggestions result in quick improvements and enhancements to the software.

Simply efficient and manageable. 
DotNetNuke can support multiple portals off of one install.  Divides administrative options between host level and individual portal level.  Allows administrators to manage any number of sites, each with their own look and identity, all off of one hosting account.

Priority on security. 
Emphasis placed on validation, encryption, “bug” tracking and potential threats.

Fully customizable.
Changes can be made to portals at all levels – from basic stylesheet elements like font type, color, and bullet points, to overall site appearance.  New skins and module containers can be easily applied to the site with no repercussion on content.

Fully localized.
Built-in multi-language localization features allow administrators worldwide to easily use and adapt DotNetNuke software for their own use.

User-friendly interface.
Well-researched interface makes it easy for users to manage all aspects of their projects.  Site wizards, help icons, and an inutuitive user interface allow universal ease-of-operation.

Easy to access community.
With a dedicated core programming team, over 350,000 registered users, and a growing legion of  third-party DotNetNuke developers, DotNetNuke hosters, and resellers, the DNN community is always close-at-hand.
