Umbraco.
Content Management System
Open-source .NET-based CMS that is flexible, user-friendly and affordable. Founded in 2005 in Odense, Denmark. The "charm CMS" of the .NET world.
What is Umbraco?
A Content Management System (CMS) is software that allows you to create, manage and publish digital content (text, media, pages) without writing code.
Umbraco is a CMS built on .NET, which means you can extend it with C#. It distinguishes itself through strong user experience: content managers find Umbraco intuitive. It also offers a headless variant (Umbraco Heartcore) for organizations that want to serve content via APIs to multiple channels.
What makes Umbraco different?
Umbraco is the "charm CMS" of the .NET world. While Sitecore feels naturally heavy and Optimizely enterprise-focused, Umbraco feels light and flexible. The user interface is modern and accessible; content managers don't need much IT knowledge.
Open-source DNA means you can download, customize and extend Umbraco for free. This has led to a vibrant community and many community extensions. You're not locked into vendor lock-in.
The traditional architecture of Umbraco is however still monolithic. With Umbraco Heartcore they're trying to solve this, but that feels like a separate offering.
Strengths
User-friendly – Intuitive backend; content managers feel at home immediately.
Very flexible – Open-source, extensible with C#; you're not limited by platform logic.
Affordable – Free open-source version or Umbraco Cloud from EUR 45/month; much cheaper than competitors.
Strong community – Vibrant partner network, many extensions and best practices.
Who uses Umbraco?
Umbraco is strongly represented among Dutch and European organizations from small to medium size.
Van Kaathoven – Waste management, 30% more conversions
Groenhart – Construction wholesaler
Council of the EU – Public services
Baker Tilly Int. – Accountancy firm
Zodiac – Harley Davidson parts

Our perspective
Umbraco is solidity and pragmatism. It's the "middle way" between fully open-source WordPress (too light for enterprise) and Sitecore (too heavy). For medium-sized Dutch and European companies we see Umbraco much more often as the right choice than Sitecore.
Suitable for
Small to medium businesses and SMEs
Teams with .NET knowledge that want flexibility
Organizations that want to avoid vendor lock-in by choosing open-source
Dutch and European companies; strong partner network in these regions
Consider carefully
Traditional architecture: still not natively headless (Heartcore is separate product)
Scalability limits for very large, high-traffic sites
Smaller ecosystem than Sitecore; fewer third-party integrations
Enterprise features missing (advanced personalization, A/B testing)
Is Umbraco suitable for enterprise?
Limited. Umbraco falls short in enterprise requirements like advanced personalization, testing engines, and complex multi-site governance. For enterprise scale (>10 million visitors/year, multiple brands, 100+ content editors) Umbraco quickly outgrows its jacket. For medium-sized enterprise (up to ~5 million visitors) it can work fine.
Summary: Umbraco is a solid, affordable CMS for small and medium businesses. It excels through user-friendliness and flexibility. If you need enterprise scale or advanced testing capabilities, look further. But for a Dutch company that wants to confidently run open-source without vendor lock-in: Umbraco is a solid choice.

Integrations & ecosystem
Umbraco integrates with Microsoft SQL Server and Azure (via Umbraco Cloud). Community extensions connect with Stripe (payments), SendGrid (email), Google Analytics, and many e-commerce platforms. The platform offers REST APIs allowing you to serve content to external applications.
Implementation
Umbraco implementation takes 1-3 months for a medium-sized project. The learning curve is flat thanks to the intuitive interface. You can use Umbraco Cloud (managed by Umbraco A/S on Azure) or self-host on your own server.
Support & community
Umbraco offers community support (free forum) and commercial support via partners. The community is very active with regular webinars and conferences (Codegarden). Documentation is well maintained; many tutorials available.
AI & product development
Umbraco is experimenting with AI features (AI-assisted content generation, predictive analytics) but this is still in its infancy. The roadmap adds modern capabilities incrementally, but Umbraco follows rather than leads in this area.
Compare with alternatives
How does Umbraco compare to Sitecore?
Umbraco is younger, more modern and much cheaper. Sitecore offers more enterprise features (advanced personalization, testing) but feels older and heavier. If you have the choice: Umbraco is for most medium-sized use cases the better answer. Sitecore is only really needed if you have complex B2B scenarios with advanced personalization/testing.

Sitecore – Enterprise DXP; much more functional but more expensive and heavier
