Next.js projects delivered for London businesses
Next.js is the most popular React framework for production websites and web applications. It combines server-side rendering, static site generation and edge computing. The result is 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. They rank higher on Google and convert more visitors into customers.
Our Next.js stack includes TypeScript for type safety and Supabase for database and authentication. We use Vercel for deployment and hosting, plus Tailwind or custom CSS for styling. This modern architecture removes the security flaws, plugin bloat and performance issues that plague WordPress sites. It also gives 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. That means dynamic meta tags, Open Graph images, JSON-LD structured data, XML sitemaps and robots.txt. We also add 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. PHP rendering means slow page loads. Plugins create security flaws. The platform needs constant maintenance. Poor Core Web Vitals scores also hurt your Google rankings more and more. Next.js removes all of these issues. It gives 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. So 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 to configure. Your site runs on Vercel's global edge network. It serves pages from the data centre closest to each visitor. The result is 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. This covers admin dashboards, customer portals, booking systems, content management systems, e-commerce platforms and SaaS products. We build them all with the same high-performance architecture. Supabase provides the database, authentication and real-time capabilities. Next.js API routes handle the 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. We build API integrations that connect your website to HubSpot, Stripe and other business tools. We also build automated workflows that keep your site content fresh and up to date.
Our Process
How We Work
Our proven process delivers consistent results for London businesses
Discovery & Architecture
We start with your business goals, content structure and technical requirements. Then we design the site architecture, data model and integration plan. We do all of this before writing any code.
Design & Prototyping
We create responsive designs that look premium on every device. They use mobile-first layouts and smooth animations. A design system keeps every page visually consistent.
Development & Integration
Our team builds the Next.js application with TypeScript. We integrate your CRM, payment systems and third-party APIs. We also implement the full SEO infrastructure, including structured data and sitemaps.
Testing & Performance
We test on real devices, optimise images and audit accessibility. We make sure every page scores 90+ on Google PageSpeed Insights before launch. Core Web Vitals compliance is non-negotiable.
Launch & Support
We deploy to Vercel and configure your domain. We set up analytics and submit sitemaps to Google Search Console. We then provide ongoing support and content updates as your business grows.
