# A Next.js development agency that builds beyond templates. > A UK Next.js development agency that builds fast, art-directed sites and apps on Next.js and Sanity — the same stack behind our own Awwwards-listed studio site. Hire Next.js developers who ship. URL: https://www.smartastudio.com/services/nextjs-development **Next.js Development** We design and build fast, editable, search-ready websites and web apps on Next.js — the framework we run our own studio on. Next.js is the React framework for production: server rendering, static generation and edge delivery in one codebase. We use it to ship sites that score in the 90s on Core Web Vitals and stay easy to change. No page builders, no bloated themes — bespoke React, art-directed, built to last. _smartastudio.com is built on Next.js + Sanity — and it is Awwwards-listed._ - **90+** — Core Web Vitals scores we build to - **App Router** — React Server Components, by default - **Nantwich, UK** — Where we design and build ## Three ways we work with Next.js. Whether you are starting fresh, moving off a slow legacy stack, or need a partner to run a Next.js app properly — this is where we come in. - Build — new Next.js sites and web apps on the App Router - Migrate — move off WordPress or a slow legacy build, without losing rankings - Optimise & run — audit, fix and maintain an existing Next.js codebase ## We run our own studio on this stack. - **Art-directed, not generated** — Bespoke design and bespoke React — no page builders, no off-the-shelf themes. If a stranger could tell it came from a template, it is not finished. - **Performance is the brief** — We build to 90+ Lighthouse and green Core Web Vitals as standard — because speed is ranking, conversion and credibility, not a nice-to-have. - **Strategy, not just execution** — We choose the right rendering strategy for the job — SSR, SSG, ISR or edge — and tie every build to a business goal: leads, sales, retention. - **A small, senior team** — You work with the people building it. No account-management layer, no offshoring, no hand-off to juniors — start to finish, senior hands. ## A Next.js build, done properly. Every engagement ships the same standard of work — the tangible things you keep. - **A bespoke React front-end** — Hand-built on the Next.js App Router — no page builder, no off-the-shelf theme. Yours to own and extend. - **Core Web Vitals in the green** — We build to 90+ Lighthouse and green field-data. Fast is a requirement, not a target we hope to hit. - **A headless CMS your team can drive** — Sanity Studio wired to the front-end, so editors change content, images and pages without touching code. - **SEO and structured data baked in** — Clean metadata, Open Graph, JSON-LD, sitemaps and canonicals — set up so you get found, including in AI answers. - **Motion that means something** — GSAP-specced animation — page-load sequences, scroll reveals, micro-interactions — art-directed, never noise. - **A clean handover** — Documented, typed code, sensible components and a repo your next developer will thank us for. ## How we work: Audit, Design, Build, Run. A clear path from goal to launch — and beyond. The same method behind every SmartaStudio build. ### Audit Duration: Week 1 - We start with what the site has to achieve, what exists today, and where the technical and content gaps are. - For migrations: we map every URL and plan redirects so search sees an upgrade, not a reset. You get: A clear scope, sitemap and technical plan. ### Design Duration: Weeks 2–4 - A bespoke design system and page designs in Figma, specced with motion — signed off before a line of React is written. You get: Art-directed designs and a component system. ### Build Duration: Weeks 4–10 - Figma to Next.js via Cursor: typed React, Tailwind and GSAP, wired to Sanity and measured against Core Web Vitals. You get: A fast, editable Next.js site or app. ### Run Duration: Ongoing - Launch, then ongoing build and design on retainer — the site keeps improving instead of quietly ageing. You get: A partner who keeps it fast and current. ## Next.js development at a glance. - **Category:** Next.js development agency (React, App Router) - **Best for:** Ambitious brands wanting a fast, bespoke, editable site or web app — and teams replatforming off WordPress or a slow legacy stack. - **Typical work:** Marketing & product sites, dashboards, member/investor/booking portals, WordPress → Next.js migrations. - **Stack:** Next.js (App Router, RSC), TypeScript, Tailwind CSS, GSAP, Sanity headless CMS, deployed on Vercel. - **Proof:** Our own Awwwards-listed site runs on Next.js + Sanity; we build to 90+ Core Web Vitals as standard. - **Engagement:** Fixed-scope projects (typically 10–12 weeks) or ongoing build & design on retainer.

It gives you server rendering, static generation and edge delivery in one codebase — which means fast pages, strong SEO and a great editing experience. It is what we build our own studio site on. **Do you build Next.js sites, apps, or both?** Both. Marketing and product websites, and full web applications — dashboards, member and investor portals, booking systems. If it runs on React, we can build and run it. **Will our team be able to edit the site?** Yes. We wire Next.js to Sanity, a headless CMS, so editors change content, images and pages through a friendly Studio — no developer required for day-to-day updates. ### Working with us **Can you migrate our WordPress site to Next.js?** Yes, and without losing rankings. We map every URL, set up redirects, carry across metadata and structured data, and cut over incrementally so search sees an upgrade rather than a reset. We measure speed before and after. **Can we hire your Next.js developers on retainer?** Yes. Beyond fixed-scope projects we offer ongoing build and design on retainer, so your Next.js app keeps getting faster and better instead of quietly ageing. **How much does a Next.js project cost?** Marketing sites typically start around £4,000–£8,000 +VAT; web apps and portals run higher depending on scope. We scope every project properly before quoting — no surprises. All prices in £ GBP. ## Got a Next.js project in mind? Tell us what you are building.
