App Router and Server Components
Server Components by default, client components only where there is interaction, and layouts that keep shared UI from re-rendering on navigation.

Capabilities
Next.js capabilities we bring to your product.
Next.js has changed a great deal since the Pages Router. We check that developers understand the App Router model properly, not just its file conventions.
Rendering chosen per route
Static pages for content, server rendering for personalised views, streaming for slow data, and caching matched to how often each page changes.
Technical SEO
Metadata, canonical URLs, sitemaps, structured data and hreflang for en-GB, generated from the same data that renders the page.
Core Web Vitals
next/image and next/font for LCP and layout shift, less client JavaScript for INP, and decisions based on field data rather than lab scores.
Route handlers and server actions
Mutations through server actions and webhooks through route handlers — each one validated and authorised, because both are public endpoints.
Vercel or self-hosted
Preview deployments on Vercel, or Docker on AWS behind NGINX with a shared cache, so every instance serves the same revalidated pages.
What we build
What we build with Next.js.
Marketing sites that have to rank, stores that have to feel quick and products that outgrew a single-page app: the Next.js work we are asked for most.
Content sites that rank
Pages built from a headless CMS such as WordPress or Sanity, so editors publish without a developer and pages refresh when content changes.
Quick product and category pages
Headless Shopify or a custom commerce API, with pre-rendered product pages, a dynamic basket and images sized for the phones customers actually use.
Marketing site and app in one
Public pages pre-rendered for search and the logged-in product rendered on demand, sharing one design system and one deployment.
Large listing sites
Location, category and listing pages generated from your data, with on-demand revalidation, internal linking and structured data.
Pages Router to App Router
getServerSideProps and getStaticProps replaced with data fetching in Server Components, one route at a time, while both routers run side by side.
From CRA to Next.js
Create React App is deprecated. We move the app onto Next.js, keep its URLs, add server rendering where it helps and retire the old build.

Pricing
Next.js development pricing.
Start with discovery, move to a fixed-price build, or run a dedicated team for a longer roadmap.
Next.js discovery sprint
From £2,000
Architecture, roadmap, cost planning, and project-risk validation
- A short strategy sprint covering technical scope, user flows, delivery plan, and budget range.
Managed Next.js development project
Fixed quote
MVPs, rebuilds, SaaS platforms, dashboards, portals, and business-critical launches
- Product planning, UX, engineering, QA, deployment, and post-launch support under one delivery owner.
Dedicated Next.js development team
From £9,500 per month
Longer roadmaps, multi-sprint delivery, and product teams that need extra senior capacity
- A stable engineering pod with weekly demos, sprint planning, code review, and transparent reporting.
Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
How we deliver
How we deliver your Next.js project.
Seven stages, the same on every project. The length of each one changes with the work; skipping one never saves time for long.

Product and technical discovery
We map your Next.js product goals, users, integrations, compliance needs, timeline, and commercial priorities before planning the build.
Goals, users and constraints agreed
- 02
Architecture and delivery plan
You get a practical Next.js roadmap with milestones, team shape, risks, estimates, and the first release path.

Design, build, and QA
Our team ships the Next.js product in controlled sprints with code review, testing, demos, and visible progress every week.
Tested software every sprint

Launch and improvement
We handle deployment, analytics, monitoring, handover, and post-launch iterations so your Next.js platform keeps improving.
Live, monitored and documented
Why Techsleight
What working with us is actually like.
No inflated numbers — just how we run projects, and what you can hold us to.
Product engineering, not ticket-taking
We ask what the software is for before we estimate it — and we will tell you when something should not be built, or should be bought instead.
AI where it earns its place
LLM features, retrieval and automation built with evaluation, guardrails and cost controls, and plain software where that is the better answer.
Full-stack under one roof
Design, frontend, backend, mobile, cloud and QA in one team, so nothing falls between suppliers.
UK-focused delivery
UK business hours, estimates in pounds, and a contract with a UK company. Our engineers are based in the UK and India.
Flexible engagement
A fixed-scope project, dedicated developers or a monthly retainer — and you can move between them as the work changes.
You own everything
Code, IP, cloud accounts and documentation are yours from day one. We sign an NDA before discovery if you need one.
Support after launch
We stay on for fixes, upgrades and new features, or hand over cleanly to your in-house team with the documentation to match.

Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
What does a Next.js development company do?
A Next.js development company plans, designs, builds, tests, deploys, and supports Next.js software. At Techsleight Labs, that can include discovery, architecture, UI/UX, API integration, QA, cloud deployment, analytics, and post-launch roadmap support.
Do you work with companies in the United Kingdom?
Yes. This Next.js development company page is focused on United Kingdom businesses. We support UK collaboration with clear written updates, weekly demos, and planned handoff points so distributed teams can move quickly.
How much does Next.js development cost?
Next.js development pricing depends on scope, integrations, user roles, design depth, compliance needs, and launch timeline. Discovery sprints start from £2,000, dedicated teams start from £9,500/month, and managed projects are quoted after scope validation.
Can you build a complete Next.js product, not just provide developers?
Yes. You can use Techsleight Labs as a full Next.js development company for strategy, design, engineering, QA, deployment, and support. You can also start with a small discovery sprint before committing to the full build.
Can you improve an existing Next.js application?
Yes. We often join existing Next.js products to fix performance, improve architecture, add features, stabilise releases, modernise UI, or prepare the system for scale. We begin with a focused audit so the first sprint is practical.
Who owns the code and product IP?
You own the code, documentation, product IP, design assets, and infrastructure setup created for your project. We can sign an NDA before discovery and work inside your repositories, cloud accounts, and project tools.
How fast can a Next.js development project start?
Discovery can usually begin within a few working days of the first call, and most projects start within 5–7 working days of sign-off. Larger builds usually need a short planning sprint to confirm scope, architecture, milestones, risks, and the right team before full development begins.
Do you provide post-launch Next.js support?
Yes. After launch, we can continue with monitoring, bug fixes, performance improvements, security updates, roadmap features, analytics, and handover support. Many clients keep a monthly retainer after the main release.
