Next.js development: fast by default
Gjethe builds websites and web applications with Next.js: marketing sites, headless e-commerce storefronts, documentation and content platforms, SaaS dashboards and multilingual sites. We use the App Router, Server Components and static generation so pages load fast and are fully readable by search engines and AI crawlers, and we migrate existing sites to Next.js.

Definition
What is Next.js development?
Next.js is an open-source React framework that adds server-side rendering, static generation, routing, image and font optimisation and API handling to React, so the same codebase can power fast websites and full web applications.
A plain React app renders in the browser, which is slow on first load and harder for crawlers to read. Next.js renders pages on the server or at build time, sends far less JavaScript to the browser and handles images, fonts and routing for you. That's why we build most projects with it, including this website, from small marketing sites to multi-tenant SaaS.
Who is it for?
Sites where search traffic matters
Server-rendered pages, metadata APIs and Core Web Vitals give a strong technical base for SEO.
Headless commerce
Custom storefronts on Shopify, Medusa or another commerce back end, with complete design freedom.
SaaS products and dashboards
One framework for the marketing site, docs and the logged-in product.
Multilingual sites
Built-in internationalised routing makes per-language URLs and hreflang straightforward.
Teams migrating from older stacks
Moving from Create React App, Gatsby, the Pages Router or a monolith to modern Next.js.

Which Next.js rendering mode for which page?
| Mode | What it does | Good for |
|---|---|---|
| Static generation | Pages built ahead of time and served from a CDN | Marketing pages, docs, blog posts |
| Incremental revalidation | Static pages refreshed in the background when content changes | Catalogues, CMS-driven pages |
| Server rendering | Pages rendered per request | Personalised or fast-changing data |
| Client components | Interactive parts hydrated in the browser | Forms, filters, dashboards |
Why Server Components matter for performance
With the App Router, components render on the server by default and send HTML rather than JavaScript. Only the interactive parts (a form, a filter, a menu) ship code to the browser. On content-heavy pages this cuts the JavaScript users download dramatically, which improves how quickly pages become usable on phones.
Data fetching happens on the server too, close to your database or CMS, so secrets stay off the client and pages arrive complete. Combined with streaming, users see meaningful content quickly even when part of the page waits on slower data.
SEO foundations in every Next.js build
- Unique titles, descriptions and canonical URLs from the Metadata API
- XML sitemap generated from your content
- robots.txt and AI crawler policy
- Structured data (JSON-LD) matched to page types
- Open Graph images generated per page
- hreflang for multilingual sites
- Fast Core Web Vitals on real devices
What we build with Next.js
Marketing websites

Tools, and what shapes your quote
Pricing is based on your project and agreed in your quote. These are the things that move it.
| Factor | Why it matters |
|---|---|
| Number of templates | Each page type needs design, data fetching and testing. |
| Content model | A rich CMS with many content types and relationships takes more set-up. |
| Application features | Authentication, dashboards and server logic make it an app rather than a site. |
| Languages | Each locale adds routing, translations and SEO configuration. |
| Migration | Moving from another framework involves porting components and redirecting URLs. |
| Hosting choice | Self-hosting on your own cloud needs more set-up than Vercel. |
| Area | Tools |
|---|---|
| Framework | Next.js (current release), React, TypeScript |
| Styling | TailwindCSS, CSS Modules |
| Content | Sanity, Contentful, headless WordPress, MDX |
| Data & auth | PostgreSQL, Prisma, Drizzle, Auth.js, Clerk |
| Hosting | Vercel, AWS, Cloudflare, Docker |
Common mistakes to avoid
What we see go wrong most often, and how a good project avoids it.
Marking everything as a client component
Adding “use client” at the top level sends unnecessary JavaScript and throws away Next.js's main advantage.
Fetching data in the browser
Client-side fetching for content pages hurts speed and SEO. Fetch on the server where possible.
Ignoring caching behaviour
Misunderstood caching leads to stale pages or needless server load. Decide per route how fresh data must be.
Unoptimised images
Raw images bypass Next.js's optimisation and slow pages; use the Image component with proper sizes.
Frequently asked questions
Why choose Next.js over a plain React app?
A plain React app renders in the browser, which is slower on first load and harder for search engines to read. Next.js renders on the server or at build time, so pages arrive complete.
Is Next.js good for SEO?
Yes. Server-rendered HTML, built-in metadata and sitemap APIs and fast Core Web Vitals make it one of the strongest technical foundations for search and AI visibility.
Can you upgrade or migrate an existing Next.js app?
Yes. We migrate projects from the Pages Router to the App Router, upgrade Next.js and React versions and move sites from other frameworks to Next.js.
Do I have to host on Vercel?
No. Vercel is the simplest option, but Next.js also runs on AWS, Azure, Google Cloud, Cloudflare or any Node.js server.
Which CMS do you pair with Next.js?
Usually Sanity for its flexibility and editor experience, Contentful for larger organisations, or WordPress when editors already know it.
Can non-developers edit a Next.js site?
Yes, through the headless CMS. Editors manage content and media; layout changes and new features go through developers.
Can Next.js handle e-commerce?
Yes, as a headless storefront on Shopify, Medusa or another commerce platform, which handles products, carts and checkout.
How do you deploy changes safely?
Every change gets a preview deployment for review, automated checks run before merging, and production deploys can be rolled back instantly.
Is Next.js overkill for a small website?
Not necessarily. Static Next.js sites are cheap to host and very fast. For a tiny site a team edits visually, Webflow can be simpler.
Can you add Next.js to an existing React app gradually?
Often, yes. Pages can be moved one route at a time while the rest of the app keeps working, which reduces risk compared with a big-bang rewrite.
How do you handle forms and server logic?
With Server Actions and route handlers in the same codebase, so contact forms, sign-ups and webhooks run securely on the server without a separate backend for simple needs.
Can a Next.js site use our existing API?
Yes. Pages fetch from your API on the server, which keeps credentials private and lets responses be cached for speed.
