Next.js projects delivered for London businesses
Next.js is the most popular React framework for building production websites and web applications. It combines server-side rendering, static site generation, and edge computing to deliver websites that are faster, more secure, and better for SEO than traditional CMS platforms like WordPress, Wix, or Squarespace. As a specialist Next.js development agency in London, Byter Digital builds websites that score 100 on Google PageSpeed, rank higher on Google, and convert more visitors into customers.
Our Next.js stack includes TypeScript for type safety, Supabase for database and authentication, Vercel for deployment and hosting, and Tailwind or custom CSS for styling. This modern architecture eliminates the security vulnerabilities, plugin bloat, and performance issues that plague WordPress sites, while giving you a website that loads in under one second on any device, anywhere in the world.
Every Next.js website we build includes full SEO infrastructure: dynamic meta tags, Open Graph images, JSON-LD structured data, XML sitemaps, robots.txt, IndexNow for instant search engine indexing, and Core Web Vitals optimisation. We do not just build websites; we build marketing assets that drive organic traffic and convert visitors.
Why Next.js Over WordPress?
WordPress powers 40% of the web, but it comes with significant trade-offs: slow page loads from PHP rendering, security vulnerabilities from plugins, constant maintenance requirements, and poor Core Web Vitals scores that increasingly impact Google rankings. Next.js eliminates all of these issues while giving you a faster, more secure, and more flexible website.
With Next.js, your pages are pre-rendered at build time or server-rendered on demand, meaning visitors see content instantly rather than waiting for a database query. There are no plugins to update, no security patches to apply, and no hosting configuration to manage. Your site runs on Vercel's global edge network, serving pages from the data centre closest to each visitor. The result: sub-second load times, 100/100 PageSpeed scores, and a website that Google rewards with higher rankings.
Full-Stack Web Applications
Beyond marketing websites, we build full-stack web applications with Next.js. Admin dashboards, customer portals, booking systems, content management systems, e-commerce platforms, and SaaS products, all built with the same high-performance architecture. Supabase provides the database, authentication, and real-time capabilities, while Next.js API routes handle server-side logic.
Our web applications are fully typed with TypeScript, tested, and deployed with CI/CD pipelines. We build admin panels that let your team manage content without touching code, API integrations that connect your website to HubSpot, Stripe, and other business tools, and automated workflows that keep your site content fresh and up to date.
