A modern stack
built for speed.
Web development at DLU ships on Next.js and React by default — with a headless CMS and infrastructure that stay fast after launch. Vue and Nuxt only when the codebase already lives there.

FAQ
Questions before
you start.
Web development projects at DLU typically fall between €600 and €25,000+, depending on scope — a landing page is not a custom CRM. After the brief we map your budget band to a realistic scope: landing, company site, e-shop, or a web app. We do not use the number to upsell features you do not need.
