What DNN is
DNN is a free, open-source content management system for the Microsoft stack. Organizations can use it to create marketing sites, online stores, member communities, intranets, knowledge bases, customer portals, and networks of sites. Editors get inline WYSIWYG editing, drafts, approval workflows, version history, multilingual localization, and media management. Multiple sites can run on one host and share access to existing themes and modules. Developers can create modules, themes, and integrations through APIs and extension points. Administration includes page- and module-level permissions and an admin log that can record more than 130 event types. Google Analytics and Azure are default connectors; Marketo, HubSpot, and SharePoint can also be connected. DNN has no built-in analytics solution, though extensions can add one. It is self-hosted and available on web and Windows. DNN Platform 10 requires Windows with IIS, .NET Framework 4.8 or later, and Microsoft SQL Server or Azure SQL Database.
