What does ByteAnt do as an Umbraco development agency?

ByteAnt is an Umbraco development agency for established organisations and digital agencies in the UK, Denmark and the rest of the Nordics, the EU and the US. We build new Umbraco websites and online shops, upgrade older sites to Umbraco 17 LTS (long-term support) and look after live sites. Our engineers work at €40 an hour, and new websites start from €3,500.

Umbraco development services

Website and e-commerce development

New Umbraco websites and online shops on Umbraco Commerce, redesigns and rebuilds, with UX/UI design and several sites or languages where you need them. For a separate front end, we build headless sites in React or Next.js, with Umbraco serving the content.

Umbraco upgrades

Older sites moved to Umbraco 17 LTS. We start with a free audit and agree a fixed price before any work begins.

See the upgrade packages

Support and maintenance

One monthly plan for live sites: security patches, fixes and small changes, done by the same engineers each month, so they know your site.

Integrations, Umbraco AI and Automate

Connections to your CRM, ERP, payments and marketing tools, such as HubSpot and Stripe. We also set up Umbraco AI and Umbraco Automate, Umbraco's add-ons for AI help in the editor and automated workflows.

Consulting, packages and extensions

A second opinion on architecture, packages and hosting. We also do Umbraco plugin development: custom packages and extensions for the backoffice, the screens your editors work in.

White-label for agencies

Extra Umbraco developers who work under your agency's brand. You keep the client and the credit, and we sign a non-solicitation clause before we start.

Why organisations choose ByteAnt for Umbraco

Umbraco specialists

Umbraco is our main platform, not one of twenty. The same engineers build, upgrade and support your site.

AI-assisted, human-reviewed

AI handles routine coding and checks, so your budget goes on the decisions that need an engineer. Every change still gets a human sign-off.

Transparent nearshore prices

Our rates and package prices are published below, so you can set a budget before the first call. Technical project management is included in the rate.

Safe by default

AI works on local copies of your site, never on your live website. Nothing goes live until it has passed test and staging.

EU contracts, NDAs, your IP

You sign with an EU company, under EU law. We sign an NDA before any code changes hands, and the code and IP are yours.

Long-term relationships

Several of our Umbraco clients have worked with us for years, as their reviews below say. The people who know your site stay on it.

We know the Umbraco ecosystem from the inside

We build for Umbraco: ByteEditor

We build for Umbraco: ByteEditor

ByteAnt is the author of ByteEditor, a commercial visual website builder for Umbraco, listed on the Umbraco Marketplace, running on 30+ production websites and supported on Umbraco 13 and 17 LTS.

Taking our own product through the Umbraco 13 to 17 backoffice rewrite showed us where upgrades and packages break, before your site meets it. The demo shows an editor building a page from ready-made blocks, without a developer.

Honest advice on packages, hosting and integrations

Most Umbraco projects turn on a few early choices. These are the ones we compare with you, and what usually decides them.

DecisionOptions we compareWhat usually decides it
HostingUmbraco Cloud, Azure or your own serversAutomatic minor updates and patches, against control and running cost; who manages it
New backoffice featuresA community package, a commercial package or a custom backoffice extensionWhether a well-maintained package already does the job; licence cost against build cost; who keeps it updated

How AI-assisted engineering makes Umbraco projects faster and safer

1. Plan and guardrails

We agree the scope, then write the rules AI must follow on your project: what it may change, what it must not touch and which tests must pass.

2. Build on a local copy

Engineers build with Claude Code and the Umbraco MCP, using Umbraco's own AI skills, our skills and specialised subagents. That keeps the code to Umbraco's conventions instead of generic AI output, and all of it happens on a local copy of your site.

3. Automated checks

AI code review, unit tests and browser tests run on every change. We compare every page before and after, so a broken layout or missing content shows up before you see it.

4. Human review and sign-off

An engineer reads every change, tests it and signs it off. Only then does it move to test, staging and your live site.

Umbraco websites we've built

topsoft: a software marketplace

We built a Swiss business software directory from the ground up on Umbraco: vendor accounts, filtered software search, a blog, events and jobs. It replaced a fragmented site with one platform.

Investment company: a new Umbraco website

Umbraco development FAQ

How much does an Umbraco website cost?

A new Umbraco website costs from €3,500 for a small site, €8,000–14,000 for a medium one and from €16,000 for a large or complex one. UX/UI design is quoted separately, so you only pay for it if you need it. Integrations, languages and the number of page types decide where your site falls.

How long does it take to build an Umbraco website?

Most first releases take 2 to 8 weeks, and a site built from ready-made blocks sits at the short end. Large builds, with several sites, languages, an online shop or many integrations, take 3 to 6 months. You get a timeline with the estimate, after a call about scope.

Can you take over an Umbraco site that another agency built?

Yes, and it's a common starting point. A free health check of the code, packages and hosting tells you what we'd fix first and what can wait. We don't need the previous agency's help, though access to the code repository and hosting makes the handover quicker.

Can you advise which Umbraco packages, hosting or integrations we should use?

Yes. The comparison table above shows the decisions we weigh most often, from hosting to search and e-commerce. You get a recommendation with the reasons and the running costs, written so you can share it with your board or IT team.

Are you an Umbraco Gold or Silver Partner?

No. Partner tiers are a paid commercial programme. We invest instead in building for Umbraco, with ByteEditor on the Umbraco Marketplace.

Is Umbraco a good choice for a mid-sized organisation?

Yes, it's one of the strongest choices for mid-sized and larger organisations. Umbraco runs on Microsoft .NET, gets regular security patches and long-term support (LTS) versions, and is backed by Umbraco HQ, which has developed it for more than 20 years. It handles many page types, several sites and languages, and integrations with your CRM or ERP, and the CMS itself is open source, with no licence fee unless you choose Umbraco Cloud hosting.

Do you work with Umbraco Cloud, Azure or our own hosting?

Yes, all three. Our Azure-certified specialists set up and run Umbraco on Azure, which gives you more control and can cost less to run; Umbraco Cloud applies minor updates and security patches for you, which suits teams without their own IT. We work with whatever you have, and we'll say if a move would pay off.

Who owns the code, and can we move to another supplier later?

You own all the code we write, from the first day, and you can move to another supplier whenever you like. Our support plan has no minimum term, only 30 days' notice.

Do you use AI on our website, and is our data safe?

Yes, under rules that protect your data. We use Claude on a business plan whose terms exclude training on customer data. AI works on a local copy of your site, never on your live website. Changes reach test, staging and live through our normal deployment, after an engineer has reviewed them. Passwords and keys are kept out of AI's reach, and you own all the code. If your policy restricts AI, we agree the rules with you before we start.

Where is your team, and what if someone is away?

ByteAnt is an Estonian company, so your contract and invoices are under EU law. Our engineers work in Estonia and Ukraine on Tallinn time: two hours ahead of the UK and one ahead of Denmark. Our founder, based in Tallinn, is the second engineer on every account, so at least two people always know your site. Your code and documentation live in your repository.

Do you sign NDAs?

Yes, yours or ours, before any code or data is shared. If your organisation has its own template, we'll sign that.

Which currencies do you invoice in, and do you charge VAT?

We invoice in EUR, GBP or USD, whichever suits you. There is no VAT for businesses in the EU or the UK with a valid VAT number, or for clients outside the EU.
