Web development in Czechia: a product built for a market outgrowing its competitors
Custom Next.js and React development for businesses in the Czech Republic — from a landing page to a complex web app. Czechia is one of Europe's e-commerce leaders, with more than 80% of internet users already shopping online. We build the product that keeps you growing with the leaders, not losing share to them.

Czechia
The market is growing,
but not every player gets a share
Czechia is one of the e-commerce leaders in Central and Eastern Europe: internet access covers nearly the entire population, and more than 80% of internet users already shop online — one of the highest shares in the EU. With that level of demand, faster and better-built sites win, not slower ones. We build sites and apps that help you compete for that demand: fast, secure code written with the same languages and engineering discipline as large tech companies — strict typing, linting, and checks at every step.

Technology
A stack known
in Brno and Prague
We use the same modern languages, frameworks, and tools as the tech companies of Brno and Prague — Brno alone hosts 45,000–50,000 IT professionals and R&D centers for Red Hat, Siemens, and Oracle, while Prague concentrates 83% of the country's startup ecosystem value. That concentration of technology raises the bar for the speed and quality customers expect from your site. React, Next.js, TypeScript, and modern infrastructure instead of builders and plugins keep your product a step ahead. We regularly move projects off template platforms onto custom code — without losing content, with faster load times and better search rankings.

Speed impact
In an overheated market,
the faster site wins
In a market with one of the highest e-commerce adoption rates in Europe, competition for customer attention is fierce — and the faster site wins. Here's what happens when companies take speed seriously:
- +8% sales
Vodafone Italy improved LCP by 31% in an A/B test — and saw 8% more sales, a 15% better lead-to-visit rate, and an 11% better cart-to-visit rate.
