The engine, not the paint
Umbraco runs your site behind the scenes. Your look, words, and brand sit on top — Umbraco keeps it all loading fast and staying online.
Yours to keep — no rent
Umbraco is open-source and free to license. No yearly platform fees, no vendor holding your site hostage. You own it.

A working miniature of the Umbraco editor, set up like a site we built: dominicanaflc.com, the Festival del Libro y la Cultura Dominicana in New York. Edit a page, publish it, add an English version, and ask the AI agent for help. The live site below only changes when you publish.
Scroll sideways to see the whole editor. Like the real Umbraco, it’s made for a computer screen.

Agent-ready
Why Umbraco is an agent-ready CMS
AI is moving from answering questions to doing work: drafting pages, translating, updating products. Umbraco is opening up to these AI agents in a controlled way, under the same rules as your team.
Umbraco’s three rules for AI
- ChoicePick the AI provider and model you trust. Umbraco doesn’t lock you into one.
- ControlYour tone of voice, permissions and guardrails apply. AI never publishes content on its own.
- ConnectionAgents connect through MCP, the open standard AI tools use to work with other software.
What that means in practice
- Public beta on Umbraco Cloud
Edit your site from ChatGPT or Claude
With the CMS Editor MCP, editors connect ChatGPT, Claude, Gemini, Copilot or Le Chat and find, create and update content in plain language. They sign in as themselves, so the assistant can never do more than they could.
- Available
AI inside the editor
Umbraco AI adds ready-made actions such as alt text, SEO titles and summaries, plus a Copilot chat that knows which page you’re working on.
- Built into Umbraco AI
A person stays in charge
AI changes wait for a manual approval before they’re saved or published, and AI activity is logged, so you can always see what happened.
- Beta and open source
Faster, better builds
For developers, the Developer MCP and Agent Skills teach AI coding tools how Umbraco works, so new features follow its best practices.
- Built in
Content any system can read
The Content Delivery API serves your content as clean, structured data, so apps, search engines and AI tools get the facts straight from the source.
What we do with it
We set up Umbraco so your team and your AI tools work from the same well-structured content, with permissions and approval steps that match how you work. The demo above shows the idea.

Why Umbraco is a smart, safe bet
No license fees
Open-source means you don’t pay to use the platform — your budget goes into your actual site, not software rent.
Seriously secure
A strong security record and a dedicated team watching for issues — it matters when your site carries your reputation.
Fast and reliable
Built on modern Microsoft .NET — quick for visitors and stable when traffic spikes.
You stay in control
Your content, your data, your choice of hosting. No lock-in to one vendor’s rules.
Grows with you
From a simple site to a large multi-language one, Umbraco scales without starting over.
Big, friendly community
Thousands of developers worldwide — so help, add-ons, and talent are always easy to find.
Why we build on Umbraco — and not the big names you’ve heard of.
Every platform has trade-offs. Here’s why we build on Umbraco for control, low running costs, and an AI-ready site — and where the big names still fit.
The freedom of open-source, the security of serious software — and the cleanest path to a site that AI recommends.
