Talk to Ethisys →What is Umbraco?
Umbraco is a popular open-source content management system built on Microsoft .NET (ASP.NET Core). It's known for a clean, editor-friendly backoffice and the flexibility to build almost anything — from marketing sites to large, integrated platforms — with full control over the front-end.
The ecosystem includes Umbraco Cloud (managed hosting with built-in deployment), Umbraco Heartcore (headless SaaS), a native Content Delivery API for headless and hybrid delivery, Umbraco Commerce for e-commerce, Umbraco Forms, and Umbraco Engage for personalization and marketing.

Umbraco upgrades & migrations
Older Umbraco 7 and 8 sites run on the legacy .NET Framework and are out of, or nearing end of, support. Moving to a current Umbraco LTS on ASP.NET Core is a rebuild of templates and custom code, not a simple update — we audit your site, migrate content and media, and re-implement templates, packages and integrations so you land on a secure, supported version.
Why Ethisys
We're a .NET specialist that delivers Umbraco alongside Sitecore, Kentico, Kontent.ai and composable stacks — so you get senior engineers, robust code, and straight advice on hosting, headless and commerce, at better value than large agencies. We support sites we didn't build, too.

What is Umbraco?
Umbraco is an open-source content management system built on Microsoft .NET (ASP.NET Core), known for an editor-friendly backoffice and full flexibility over the front-end.
