Introducing Umbraco 17: A Robust, Open Source CMS

December 30, 2025

The highly anticipated release of Umbraco 17 is officially live. This scalable, modern, editor-first CMS brings along feature enhancements, performance upgrades, enhanced security and a new UI framework that is setting itself apart from other open-source content management systems (CMS’).

After several version upgrades, Umbraco 17 represents Umbraco’s continued evolution, showing its commitment to offering its users a modern tech stack with this new long-term support (LTS) version.  Designed to support growing teams and stand up to evolving technical complexities, Umbraco 17 is a competitive CMS option for budget-conscious businesses, institutions and organizations looking for a powerful CMS . This release is more than just a version change, however. Umbraco 17 reflects a long-term commitment to current development standards and prioritizes the content editing experience. Here is a closer look at what Umbraco 17 is bringing to the CMS table.

A CMS Built to Last

Foundationally, Umbraco 17 was built to adapt and outlast evolving technical standards. Built on the long-term supported .NET 10 framework, Umbraco 17 promises a strong, secure foundation with performance consistency. With Umbraco 17, there are fewer surprises, smoother upgrades, and a roadmap that encompasses features that are competitive with other platforms.

Umbraco’s goal with this new version was to eliminate unexpected updates and ensure that the platform is stable from a development and performance standpoint. When the foundation is solid, administrators can be more intentional and spend their time on improving usability and honing features, instead of working constantly working around CMS limitations.

Umbraco Plays Well With Others

Umbraco 17 maintains its reputation as an extensible CMS - working smoothly with the tools that you use most. This upgrade aligns seamlessly with helpful tools in the Umbraco ecosystem, including: Umbraco Engage and Umbraco Forms, while also offering continued flexibility to support third-party integrations as needed.

Umbraco 17 also offers improved API connections, making connecting to  your third-party platforms and data even easier. The friendliness of the CMS is one of the reasons our team likes working within the Umbraco platform. Not only does it work well with third parties, it also lets us create completely customizable solutions without forcing sites into a one-size-fits-all setup.

The flexibility of this CMS version is beneficial for organizations with existing third-party relationships.  Whether it is analytics, CRM integrations or custom built tools, Umbraco 17 was designed to join your current tools, not replace them. With this approach, teams can extend functionality where needed without creating extra roadblocks and technical headaches. 

What Does that Mean for our Clients?

For the clients that are already using Umbraco version 13, version 17 is a really solid and simple upgrade. Aside from support longevity, Umbraco 17’s modern foundation is stable and intended to be long-lasting. In addition, the features that the CMS offers will continue to scale with the platform, making it a smart choice when approaching from an upgrade perspective.

For those considering the switch to Umbraco, whether if you are coming from a commercially licensed CMS or another open-source platform, Umbraco 17 gives you a strong foundation to start without being overly complex.
