Kentico sells Xperience by Kentico, a .NET DXP offered as SaaS or private cloud, and the older Xperience 13. Pages here cover replacing Kentico with Umbraco, the main open-source .NET CMS.
Kentico stops all support for Xperience 13, including security fixes, on January 1, 2027. This page compares upgrading to Xperience by Kentico with moving to Umbraco or another open-source CMS, the rebuild each requires, and how to stay safe if the cutover slips past the deadline.
Comparing Xperience by Kentico with MIT-licensed Umbraco for .NET teams: content modeling, page building, headless delivery, marketing features against Umbraco Forms and Engage licenses, SaaS or private cloud against self-hosting or Umbraco Cloud, and LTS cycles.
Moving a Kentico 12, 13 or Xperience by Kentico site to Umbraco: mapping page types to document types, moving content and media, rebuilding widgets and forms, replacing marketing features, keeping URLs and choosing an Umbraco LTS version to land on.
Cost of ownership by component: Kentico's tiered licenses and SaaS service plans against free Umbraco CMS plus paid Forms or Engage licenses where needed, hosting or Umbraco Cloud, migration, upgrades between LTS releases and the developers who maintain it.
