Next.js App Router with React Server Components, Strapi or Laravel back ends, Shopify headless commerce and AI integrations. Production-grade, built by senior engineers.
ISO 9001 & 27001
What is Next.js development?
Next.js development is building web applications with Next.js: the React framework with the App Router, React Server Components and built-in support for server-side rendering, static generation and edge deployment. The front end is connected to a back end such as Strapi or Laravel, or to a headless Shopify store for ecommerce. Because rendering and data fetching are set up per component, load time can be controlled in fine detail, resulting in high scores on Core Web Vitals such as LCP, INP and CLS. Next.js is maintained by Vercel and is the default choice for React projects with strict performance requirements.
Built for clients including Tata Steel, M&G Investments, Digistore24, Toppers in Concert, Bar-le-Duc and Loogman
These are the bottlenecks we see most often at organisations moving to Next.js: slow rendering, a locked-in architecture and a site that can't handle peak load.
Core Web Vitals fall short
The current site, often a WordPress theme, a Create React App or an older Gatsby build, renders slowly on mobile. LCP and INP stay above Google's thresholds, and that costs rankings, ad spend and conversion.
Front end and CMS are locked together
Content, templates and logic live together in one monolithic codebase. Connecting a separate CMS such as Strapi, a Laravel back end or headless Shopify means a rebuild rather than a simple integration.
Peak load takes the site down
During a launch, campaign or seasonal peak, the server-rendered set-up buckles: without edge caching or incremental static regeneration, every request hits the origin server directly.
When Next.js makes the difference, and when it's overkill
Next.js is strong at one specific combination: pages that have to load fast and be easy to find, but are also interactive and work with real data. An online store, a platform with a public side, a content-heavy site that also has to convert.
If you have a purely informational site with no interaction, a simpler set-up is cheaper to run and does the same job. If you have an application where everyone logs in and nothing needs to be indexed, you're paying for server-side rendering you never use.
- Strong where findability and interaction meet
- Overkill for a purely informational site
- Overkill for an application behind a login
Server-side, static or in the browser: it matters
Next.js can build a page in three ways, and the choice determines both your speed and your hosting bill. Static generation is the fastest and cheapest, but only works if the content doesn't differ per visitor. Server-side rendering gives you up-to-date data and costs compute time on every visit. Rendering in the browser is flexible but bad for findability.
The mistake we see most often is one choice applied to the whole site. Then a pricing page that changes once a week is rebuilt on every visit, while a stock level comes from a cache and is therefore wrong.
- Decided per page, not one choice for the whole site
- Static where possible, server-side where needed
- The reasoning documented, so it can be traced later
What a migration to Next.js means in practice
A migration is rarely a big bang, and it shouldn't be. In most cases we put Next.js alongside what's already there and move across page by page, starting with the pages where speed or findability gains the most. That keeps the site running and makes every step reversible.
Where it usually goes wrong isn't the code but the URL structure. Moving without a solid redirect plan means throwing away your positions in Google, and that's the most expensive way to get a faster site.
- Page by page, every step reversible
- URLs and traffic mapped first, then the move
- Existing addresses keep working or get a redirect
Next.js isn't a CMS with a template on top. The App Router, React Server Components and edge rendering need engineers who guard the line between server and client every day, not a team learning it on your project.
Senior engineers, no learning curve on your invoice
The App Router and React Server Components have their own pitfalls: 'use client' in the wrong place, waterfall requests, a cache that doesn't invalidate. Our engineers work in this stack every day and catch those problems before they show up in production, not after.
Performance is a build requirement, not an afterthought
We measure LCP, INP and CLS during development, not just at handover. Images through next/image, server components to keep JavaScript out of the client, and a performance budget per page so a heavy third-party script or an oversized hero image doesn't slip through unnoticed.
A front end independent of your back-end choice
For us, Next.js is the rendering layer, not the whole stack. We connect it just as easily to a Strapi CMS, a Laravel API or a headless Shopify store, and choose SSR, ISR or static rendering per page based on what that content needs.
Marketing sites and content platforms
Statically generated pages with Incremental Static Regeneration, connected to a CMS such as Strapi, so content loads fast and stays easy for your own team to manage.
Customer portals and dashboards
React Server Components fetch data server-side, with authentication and role-based access, connected to your Laravel or Strapi back end.
Headless commerce front ends
A Next.js front end decoupled from the Shopify theme, with product data and checkout staying in Shopify while layout and performance stay with your team.

Two-week sprints with a demo, continuous deployment and performance budgets from day one.
- 01
Performance audit and architecture choice
We measure the current Core Web Vitals (or set a baseline for a new project) and decide the rendering strategy per page type: which routes are statically generated, which fetch live data through Server Components and where Server Actions are needed. This is also where we choose the back-end integration (Strapi, Laravel or Shopify headless) and the hosting environment, Vercel or Cloudflare.
- 02
Setting up components and the data layer
We build the App Router structure, the component and design system and the data layer: typed API clients for your CMS or back end, a caching and revalidation strategy with ISR and on-demand revalidation, and the first Server Actions for forms and mutations. This phase decides whether the app can grow without performance suffering.
- 03
Build sprints with preview deployments
We work in two-week sprints. Every pull request gets its own preview environment, so you can follow along and test as we go. Every merge runs automatically through Lighthouse CI, so a performance regression shows up immediately rather than after launch.
- 04
Performance and accessibility hardening
Before launch we test LCP, INP and CLS on realistic network conditions, along with bundle size per route and accessibility to WCAG. Where needed, we split bundles further, move logic to the server or tighten image and font caching at the edge.
- 05
Edge deployment and launch
The deployment pipeline to Vercel or Cloudflare goes live, including edge caching, redirects and any domain migration. Monitoring for Web Vitals, errors and uptime is switched on before traffic is moved across, so a regression is visible straight away rather than arriving as a complaint.
- 06
Ongoing development and performance monitoring
After launch we keep tracking Core Web Vitals in production, not just in a test environment. We test new features and integrations for their impact on load time before rolling them out, so performance doesn't slowly slip as the application grows.
A Next.js platform is never finished at launch
- MonitoringWe monitor Core Web Vitals, server errors and API latency through Vercel or Cloudflare Analytics and Sentry.
- Performance evaluationWe check load times, bundle size and rendering performance against the performance budgets set during the build.
- Security & updatesWe patch Next.js, React and dependencies, and check edge functions and API routes for vulnerabilities.
- Ongoing developmentWe add new pages, features and integrations with Strapi, Laravel or headless commerce.
- OptimisationWe refine caching, image optimisation and code splitting to keep Core Web Vitals sharp.

Next.js that is measurably faster, not just faster-feeling.
Lighthouse 100/100
The headless Next.js platform we built for Sprints & Sneakers scores full marks on performance, accessibility, best practices and SEO, with an LCP under 1.2 seconds.
Measurable results after launch
Within three months of launch, organic traffic rose by 180%, a direct result of the technical foundation and content architecture we set up together.
What is Next.js and why does Your Tech Club choose it?
Next.js is a React framework that offers server-side rendering, static generation, edge deployment and file-based routing out of the box. We use it as standard for projects where load time, SEO and scalability come together, because the framework itself already solves problems you would otherwise need separate tooling for.
How much does a Next.js project with Your Tech Club cost?
For a marketing website with a CMS integration, the number of templates and integrations sets the price. A custom web application with authentication and roles costs between €40,000 and €120,000, and a multi-tenant platform starts from €80,000. The exact price depends on scope, integrations and whether a back end also needs to be built.
Does Next.js work with a Strapi or Laravel back end?
Yes, that's actually the combination we build most. Next.js then handles the front end and rendering, while Strapi as a headless CMS supplies the content or Laravel as an API handles the business logic, via a REST or GraphQL integration.
What are Core Web Vitals and how do you make sure they're good?
Core Web Vitals are the metrics Google uses to assess load time, interactivity and visual stability: LCP, INP and CLS. We build for them deliberately, with next/image for images, server components to keep JavaScript out of the client, and a performance budget that's monitored during development, not just measured afterwards.
App Router or Pages Router, which do you use?
We build new projects with the App Router and React Server Components as standard, since that architecture has been stable since Next.js 13. We only use the older Pages Router when maintaining or gradually migrating an existing project that still runs on it.
Can an existing website or online store be moved to Next.js?
Yes, we do that regularly, usually from WordPress, an outdated React project or a monolithic PHP application. The migration is normally phased by section or page type, so the site stays online and URLs, redirects and structured data are preserved for SEO.
What hosting does a Next.js project run on?
We deploy to Vercel when fast delivery and the latest Next.js features come first, and to Cloudflare or an EU data centre when data location or hosting costs at scale weigh more heavily. We decide together which fits, based on compliance requirements and expected traffic.
