iO is your Umbraco partner: User experience above everything


As an Umbraco Gold Partner, we know all about it: Umbraco is the most user-friendly CMS on the market. It's no surprise that it's popularly known as "The Friendly CMS".

Is your website using this headless CMS? Then it will be fully custom-made, search engine-friendly, and supported by all modern browsers.

In other words: Umbraco is the platform of choice for achieving online success.

Why choose Umbraco?

Umbraco is intuitive and easy to use. Whether you are using the open-source platform or the headless Umbraco Heartcore, you won't be bombarded with options — and yet, there are more than enough of them. With Umbraco, you have complete control over every aspect of your website.

The advantages of Umbraco

Umbraco is an open-source CMS based on Microsoft's ASP.NET technology. Not sure what that means exactly? No worries: we have listed the main benefits of working with Umbraco for you.

Radical flexibility

Umbraco gives you exactly what you need: a flexible, future-proof CMS that grows with your organisation. Expanding with standard packages or customisation? No problem at all. Linking up with external systems? Yes, please!

Open-source software

Umbraco is an open-source CMS — the base package won't cost you a penny. You only pay for the technical construction of the website, and to expand the system with extra integrations and modules.


Umbraco manages websites of all calibres — from the bakery on the corner to multinationals with million-dollar budgets. Think of brands like Red Bull, Microsoft, Vogue, and Peugeot. No digital dream is too crazy for Umbraco.

Ease of use

Umbraco focuses on user-friendliness, with a user interface that makes sense. You can start working with the CMS right away, without having to endure hours of training first. Moreover, Umbraco can be tailored to your own requirements without any worries.


Umbraco is built on Microsoft's latest .NET technology. Moreover, an independent team regularly tests the system, so that Umbraco can guarantee up-to-date security. The community also makes adjustments where necessary.

Private hosting service

Want to enter the cloud? Don't look too far. Umbraco has its own hosting service (Umbraco Cloud), which is hosted by Microsoft Azure. This gives you access to handy workflows and eliminates time-consuming, manual updates.
