FAQ
React & Next.js Development - FAQ
React is the world's most popular frontend library, used by Meta, Netflix, and Airbnb. Next.js adds server-side rendering, automatic code splitting, and API routes - delivering blazing-fast performance and excellent SEO out of the box.
Simple Next.js websites start from €2,400. Complex web applications with authentication, databases, and third-party integrations typically range from €4,000–€15,000+ depending on features and complexity.
Excellent. Next.js supports server-side rendering (SSR) and static site generation (SSG), meaning search engines see fully rendered HTML. Combined with built-in meta tag management and fast load times, it's one of the best frameworks for SEO.
Yes. We regularly migrate sites from WordPress, older React SPAs, and other platforms to Next.js. We preserve your content, SEO rankings, and URL structure while dramatically improving performance.
Yes. Nuxt.js is the Vue.js equivalent of Next.js, and it's actually our primary framework - this very website runs on Nuxt. We recommend React/Next.js or Vue/Nuxt based on your project requirements and team preferences.
React and Next.js Development for High-Performance Web Apps
React and Next.js have become the gold standard for building fast, interactive, and scalable web applications. React's component-based architecture and Next.js's server-side rendering, static generation, and API routes make them ideal for projects that demand exceptional performance and developer experience. Kosmoweb's development team specializes in building production-grade React and Next.js applications for businesses in the Czech Republic and internationally.
We use React and Next.js for a wide range of projects, from corporate websites with complex content requirements to full-featured web applications and SaaS platforms. Next.js's built-in optimization features, including automatic code splitting, image optimization, and incremental static regeneration, ensure your site loads fast and scores well on Core Web Vitals metrics that Google uses for ranking.
Choosing between React and Next.js versus other options like WordPress depends on your project's complexity and goals. Our guide to WordPress versus custom development can help you evaluate which approach makes sense. For projects that require dynamic data, real-time features, complex user interfaces, or tight integration with backend systems, React and Next.js are typically the superior choice.
