Web development Denmark
UnderStack builds company websites and web platforms for businesses in Denmark and across Europe: fast, readable on every device, and structured so that both customers and search engines understand what you offer.
If you would prefer to talk through more details, we can find a time that works.
01
Most companies that contact us already have a website. It looks acceptable, but it does not do its job: visitors cannot tell within a few seconds what the company sells, pages load slowly on a phone, the route to contact is buried, and nobody can say which pages produce enquiries. Typical situations are a consultancy whose services are described in internal jargon, a manufacturer whose product range lives in PDF catalogues that search engines never read, a clinic that still takes bookings by phone because the form never worked properly, or a trades business that has outgrown a page-builder template. In each case the problem is structural, not cosmetic. We rebuild the site around the questions a buyer actually asks, in the order they ask them, and make every page fast, indexable and measurable.
02
The scope follows the job the site has to do. A focused company website is often the right first release. When the business later needs logins, customer data, workflows or recurring integrations, the same codebase grows into a web platform instead of being thrown away and replaced.
03
Every project follows the same phases. You see working pages early, and each phase ends with something concrete you can review before the next one starts.
04
We build with React and TypeScript and style with Tailwind CSS. Pages are rendered to static HTML at build time, so the full content is in the document that a search engine or a slow phone receives, without waiting for JavaScript. Sites are served from Cloudflare's edge network, which keeps response times short across Europe. Each page has exactly one canonical URL, unknown addresses return a real 404, and structured data, hreflang and the sitemap are generated from the same route configuration as the pages, so they cannot drift apart. Linting, tests, a type check and an automated SEO validation run before every deployment, and analytics load only after the visitor consents. This website is built exactly this way, and its code is public on GitHub.
05
Three things on your side decide how smoothly the work runs. The first is content: the text, images and facts about your services are the slowest part of most projects, so we agree early who writes what, and we help structure it. The second is one person who can make decisions about scope and wording, so questions are answered in days rather than weeks. The third is access to what already exists: the current site, the domain, analytics and Search Console. With those in place, the build itself is predictable, and the launch can be planned around your own calendar instead of ours.
06
There is no fixed price list for web development, because cost follows the number of page types, the state of your content, the integrations and the languages involved. A small, precise first release is usually the cheapest way to learn what the site needs next. Our guide to business website costs in Denmark explains the drivers in detail. For individuals, freelancers and very small businesses, the For You page lists starting prices for personal and small business websites. In both cases you get a clear quote before any work begins.
It depends on the number of page types, how much content already exists, the design depth, integrations and languages. We do not quote before the scope is clear. After a short clarification you get a written quote, and the cost guide linked below explains what moves the price.
No. UnderStack is based in Aarhus and works remotely with companies in Denmark and the rest of Europe. This site itself is published in Danish, English, Swedish, German and Spanish.
Technical SEO is part of every build: indexable HTML, canonical URLs, metadata, structured data, sitemap, redirects and page speed. We do not sell rankings, because position in search also depends on competition, content and authority.
A rebuild is planned as a migration. Every old URL is mapped to its new address and redirected, pages that already perform keep their topic and content, and the sitemap is resubmitted at launch. That removes the usual causes of traffic loss, although no one can guarantee positions.
With Diego Posleman, who designs and builds the site. UnderStack is a small independent studio, so there are no account managers between you and the person doing the work.
Yes. Because the site is built as a typed React application rather than a template, user accounts, roles, dashboards and integrations can be added to the same codebase when the business needs them.
That is decided in the scope phase. If content changes a few times a year, it is simpler and cheaper to keep it in the codebase and let us make the changes. If your team publishes regularly, an editing interface is included in the scope.
