## What it is
DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) built on the Microsoft/.NET ecosystem, used to build commercial websites, intranets, community portals, and extranets. It ships with multi-site support, localization, themes, drag-and-drop editing, REST APIs, and a large extension marketplace.

## Use cases
- build a commercial or community website on .NET
- run multiple sites from a single CMS installation
- manage website content with in-place WYSIWYG editing
- create a multilingual website out of the box
- extend a CMS with custom modules and third-party extensions
- manage site security roles and protected content
- manage site content via REST APIs

## When to choose
- your team is on the Microsoft stack (IIS, SQL Server, ASP.NET)
- you need a mature, extensible CMS with a large extension store
- you need multi-site and multi-language support out of the box
- you want community-driven open source with long-term track record

## When to avoid
- your hosting is Linux-only without .NET/IIS support
- you prefer a lightweight static site or headless-first architecture
- you need a CMS in a non-.NET language ecosystem
- you want minimal setup without SQL Server
