Next.js Development Services
Next.js is the React framework teams reach for when a single-page app stops being enough: server rendering so search engines see real content, streaming so the page feels fast, and one codebase covering both the frontend and its API. We build new Next.js products, migrate aging React codebases onto the App Router, and tell you when plain React or SvelteKit would serve you better.
Our Next.js Development Services
End-to-end Next.js work, from a first build to rescuing an aging React codebase
Custom Next.js Applications
Production Next.js products on the App Router, with server components where they help and client components where they are actually needed.
- App Router & React Server Components
- Streaming SSR
- Incremental Static Regeneration
App Router Migrations
Move Pages Router, Create React App, or Vite single-page apps onto the App Router in reviewable stages, without freezing feature work.

- Route-by-route cutover
Core Web Vitals & Performance
Fix the LCP, INP, and CLS problems that hold back rankings and conversion, then keep them fixed with budgets in CI.
- Bundle and payload reduction
- Image and font strategy
- Performance budgets in CI
Headless CMS & Commerce
Next.js front ends over the content and commerce systems your team already runs, with caching that editors can actually predict.
- Headless CMS integration
- Commerce storefronts
- Draft mode and revalidation
API Routes & Backend-for-Frontend
Route handlers and server actions that keep secrets on the server and give your frontend one coherent data layer.
- Route handlers & server actions
- Auth and session handling
- Typed data access
Deployment on Vercel or Your Own Cloud
Ship on Vercel when the workflow is worth it, or self-host on AWS when residency, cost, or platform policy says otherwise.
- Vercel and self-hosted AWS
- Docker and Node runtime
- Preview environments & CI/CD
Why Choose Next.js?
Next.js gives you server rendering and the React ecosystem in one framework, which is why it is the default for teams that need both reach and hiring depth
SEO That Actually Works
Server-rendered HTML and the metadata API give crawlers real content instead of an empty div waiting on JavaScript
Faster Perceived Load
Streaming and partial prerendering let the page show useful content while slower data is still resolving
One Codebase, Both Halves
Frontend and API live together, so a feature is one pull request rather than a cross-team negotiation
A Talent Pool You Can Hire From
React is the largest frontend hiring pool there is, so handing the codebase to your own team later stays realistic
Our Proven Development Process
A delivery process built around reviewable increments rather than a big reveal at the end
Discovery & Architecture
Rendering strategy, data flow, and caching decided up front, because these are expensive to reverse later.
Iterative Delivery
Short cycles with working previews on every pull request, so you review the running app and not a status report.
Testing & Performance
Playwright end-to-end coverage, Vitest units, and Core Web Vitals checked in CI before release.
Launch & Support
Deployment on Vercel or your own AWS account, monitoring, and ongoing maintenance.

Next.js Development FAQs
Straight answers to what founders and CTOs ask before choosing Next.js
Should we use Next.js or plain React?
Use Next.js when pages need to be indexed, shared, or loaded fast on a first visit: marketing sites, commerce, dashboards with public surfaces, anything where SEO matters. Stay on plain React with Vite when the product sits entirely behind a login and nothing needs to be crawled, because then server rendering adds infrastructure and cost for no benefit. We will tell you which case you are in during discovery rather than defaulting to the bigger framework.
When is SvelteKit the better choice than Next.js?
SvelteKit produces smaller bundles and is genuinely simpler to reason about, so it wins on content-heavy sites and on teams that value a small codebase. Next.js wins when you need the React ecosystem: a specific component library, a large existing React codebase, or the ability to hire quickly. We build in both and have no incentive to push one, so the honest answer usually comes down to hiring and existing code rather than benchmarks.
Can you migrate our Pages Router app to the App Router?
Yes, and the two routers can run side by side, so this does not have to be a big-bang rewrite. We typically move one route group at a time, starting with something low-traffic to establish the patterns, then work through the rest while feature delivery continues. The risky parts are usually data fetching and auth, so we sequence those deliberately rather than last.
Do we have to host on Vercel?
No. Vercel is the smoothest path and we use it often, but Next.js self-hosts on Node or in Docker, which is what we do when data residency rules, an existing AWS commitment, or cost at scale point that way. We will lay out what you actually give up self-hosting, mostly some edge and image-optimisation convenience, so the decision is made on facts.
How do you handle Core Web Vitals?
We measure before changing anything, because most Next.js performance problems are payload and data-waterfall issues rather than framework issues. Typical work is trimming client bundles, moving work to server components, fixing image and font loading, and removing render-blocking third-party scripts. We then put budgets in CI so a future pull request cannot quietly undo it.
Can you work with our existing React team?
Yes. A common engagement is that we set the architecture, establish the App Router patterns, and do the first few features alongside your engineers, then hand over. We write the code review notes and documentation as we go specifically so the handover is real rather than a slide deck at the end.
What drives the cost of a Next.js project?
Mostly the number of distinct page templates, how many external systems the app has to integrate with, how much of the data is genuinely dynamic, and whether an existing codebase has to be migrated rather than replaced. Auth, roles, and multi-tenancy add more than teams expect. We scope a discovery sprint first and give a fixed estimate off the back of it, rather than quoting from a feature list.
