Web Development
Modern, fast, premium-quality websites and landing pages built with the latest web technologies.
A website is your company's digital storefront — often the first impression your prospective customers receive. A slow, outdated website, or one that renders poorly on mobile, loses visitors in moments. KARTREND Kft. develops websites that load within 2 seconds, look impeccable on mobile, and convey a premium feeling to the visitor within the first 3 seconds.
Our technology stack is a deliberate choice: Next.js 15, React 19, TypeScript, Tailwind CSS, Framer Motion. This combination currently provides the best performance / development speed / maintainability ratio on the market. This site (ai-webshop.hu), nanotrans.hu and balatonkertmester.hu were all built with this stack.

What does "premium quality" mean?
Perfect Core Web Vitals
LCP < 2.5s, FID / INP < 200ms, CLS < 0.1. All Google ranking signals in the green — which means Google ranks your site higher in search results.
Mobile-first responsive design
60-70% of visitors come from mobile. We design every site for mobile first, then scale up to desktop.
SEO-first approach
Server-side rendering, structured data (Schema.org), Open Graph, Twitter Cards, sitemap, robots.txt, canonical URLs, hreflang. Google can index your site from day one.
Accessibility (a11y)
WCAG 2.1 AA compliance. Keyboard navigation, screen reader compatibility, proper color contrast, ARIA attributes.
Purposeful animations
Framer Motion-based scroll-triggered animations, parallax effects, hover interactions — but never gratuitously. Animation serves the user experience.
Dark and light theme
next-themes based dark / light mode support, with automatic switching based on system preference.

Frequently asked questions
How much does web development cost?
A simple one-page marketing site costs €700-1,400; a 5-10 page corporate website with custom design, €1,700-4,000; a multilingual complex platform, €5,500-13,500. CMS integration adds €550-1,400.
How long does it take?
A simple marketing site takes 1-2 weeks; a medium-complexity site, 3-6 weeks; a multilingual complex platform, 6-12 weeks. Faster delivery is possible at a premium.
What do I get at the end?
Full source code (GitHub repository access), a Docker image, deploy configuration and documentation. The site is fully yours — you can migrate it elsewhere at any time.
Can you make the content editable?
Yes. With Headless CMS (Sanity, Strapi, Payload) integration, you can update content yourself through a simple admin interface, while the site remains lightning fast.
Wouldn't WordPress be cheaper?
A basic WordPress site can indeed be cheaper. But with WordPress, performance rarely reaches Next.js levels, maintenance (plugin updates, security patches) is a continuous burden, and complex features become increasingly expensive. Long term, the Next.js stack is often both cheaper and faster.
