umbraco.comrepositorydocspricingplugins
Umbraco CMS is a content management system built on .NET, with a built-in back office for editors, Razor views for templates and language variants for multilingual sites. A Content Delivery API is built into the CMS and must be enabled in configuration. It returns JSON over HTTP GET, so the same site can also be used headless. On SQL Server the database needs a case-insensitive collation, and WebSockets are recommended for SignalR.
Worth knowing
The CMS is MIT-licensed, while the company sells Umbraco Cloud hosting, Heartcore and enterprise support. Several add-ons are paid and are separate from the free CMS.
