Slovakia
We know the market,
not just the country name
DLU Development builds web products for businesses in Slovakia: sites and apps that run fast, secure, and without the ceilings of no-code builders. We write code in the same languages and with the same engineering discipline as large technology companies — strict typing, linting, and checks at every step. The Slovak website market is flooded with builder-based solutions that quickly hit a ceiling on speed, security, and SEO. We work differently: custom React and Next.js code that holds up under load, is secure by default, and scales with the business.

After launch we stay on: updates, security patches, and priority support so the product keeps shipping, not freezing.

Built like
big tech ships
We build with the same languages, frameworks, and tooling that large technology companies use — React, Next.js, TypeScript, modern infrastructure instead of builders and plugins. That keeps clients a step ahead, because every second of load time affects search rankings. We regularly move clients off template platforms and builders onto custom code — no content lost, faster, and better positioned in Google.

Speed impact
Speed isn't a
technical detail — it's revenue
Every extra second of load time means lost sales, leads, and customers walking straight to your competitors. Here's what happens when companies take speed seriously:
- +8% sales
