(How we work)
Content model first.
Code second.
Content Modelling
Document types, compositions, and editorial workflow agreed before a line of Razor is written. Changes at this stage are free, after build they're expensive.
Design
Figma designs mapped to Umbraco block editors and document types. Editorial UX considered at design stage, not as an afterthought.
Build
.NET, Razor, and TypeScript frontend. Unit tests for business logic. Staging deploy reviewed before launch.
Deploy & Handover
Azure or Umbraco Cloud deployment. Content team training. Post-launch monitoring and support.
(FAQ)
Umbraco questions,
answered frankly.
What is Umbraco and who is it for?
Umbraco is an open-source .NET CMS used by enterprises, government bodies, and large organisations that need a flexible, scalable CMS on the Microsoft technology stack. Its main advantages are a completely flexible content model, strong multi-site support, a clean editorial interface, and enterprise-grade .NET hosting options. It's especially popular with organisations that have existing .NET infrastructure.
Is Umbraco free?
Umbraco CMS is open source and free. You can self-host on any Windows or Linux server. Umbraco Cloud is the official managed hosting platform, it adds structured deployments, Git-based content sync, and managed infrastructure, starting from around £40/month per environment. Umbraco Heartcore is the managed headless (SaaS) option. Licensing costs are zero for the CMS itself.
Should we use Umbraco Cloud or self-host?
Umbraco Cloud is strongly recommended for most projects. It provides structured content/code deployments between Development, Staging, and Production environments, a significant advantage over manual deployments. Self-hosting on Azure, AWS, or on-premise makes sense when you have existing infrastructure, specific compliance requirements, or need to integrate Umbraco deeply with other .NET services on the same server.
How does Umbraco compare to WordPress for enterprise?
Umbraco is better than WordPress for enterprise in several ways: the .NET stack integrates naturally with Microsoft infrastructure, the content model is more structured and maintainable at scale, multi-site management is more robust, and the security model is stronger. WordPress has a much larger plugin ecosystem and lower initial development cost. Umbraco requires more upfront investment but produces a more maintainable long-term result for complex requirements.
How much does Umbraco development cost?
A standard Umbraco marketing site with custom document types and theme typically costs £8,000–£18,000. A larger enterprise site with multi-site, integrations, and custom Backoffice extensions typically costs £20,000–£50,000. Umbraco version upgrades range from £4,000–£15,000 depending on customisation complexity. Flat written quote after a free discovery call.
Can Umbraco be used headlessly?
Yes. Umbraco 12+ includes a built-in Content Delivery API that exposes your content as JSON, making it usable as a headless CMS backend. We pair this with a Next.js frontend for maximum performance and design flexibility while keeping the familiar Umbraco Backoffice for editorial teams.
