Umbraco

Umbraco is an open-source content management system built on Microsoft .NET, ASP.NET Core and C#. It supports traditional website delivery, headless architectures and hybrid implementations.

The platform separates a free CMS core from managed Umbraco Cloud hosting and paid add-ons. Its backoffice provides content authoring, media management, user administration, multilingual configuration and customizable editorial interfaces.

Umbraco is suited to organizations, developers and digital agencies that need control over website structure, presentation, integrations and deployment. The company was founded in 2003, while its open-source CMS release dates to 2005.

Core features include content authoring, media management, previewing, scheduled publishing, revision tracking, audit trails and split-view editing. Document types and property editors let development teams define structured content models.

Umbraco supports multilingual publishing and content delivery to websites, mobile applications, IoT experiences and other front ends. The platform can run on Windows, macOS or Linux through its modern .NET stack.

Developers can extend the CMS through the Management API, Content Delivery API, C# services, backoffice UI components, webhooks, NuGet packages and the Umbraco Marketplace.

Official add-ons include Umbraco Forms, Commerce, Workflow, Engage and UI Builder. Umbraco.AI provides configurable AI connections, contexts, profiles, prompts and agents inside the backoffice.

The Umbraco CMS core is free and open source. It includes content authoring, media management, user management, multilingual setup, design control, marketplace access, customizable backend capabilities, headless APIs and webhooks.

Umbraco Cloud adds managed Microsoft Azure hosting, security updates, deployment support and additional environments. Cloud plans begin at €45 per month for Starter, €280 per month for Standard and €730 per month for Professional. Enterprise pricing is custom.

Umbraco Cloud offers a 14-day free trial without requiring a credit card. Users can also download and run the CMS locally without a time-limited trial.
