Next.js · QalbIT
Next.js is not the point. The wait is.
We build with Next.js because rendering strategy is a decision, not a default: server rendering where a page needs to rank, static generation where content barely changes, and client interactivity kept to the parts of the page that actually need it.
Nobody asks for Next.js by name. They ask why a page that should rank never got indexed, or why a page that never changes still ships as a client bundle Google has to execute just to read.

What we build with Next.js
Next.js development built around rendering strategy, not just components.
We help founders and teams use Next.js for what the framework actually solves: choosing server rendering, static generation or streaming per route, and building the App Router structure around that choice instead of defaulting to client rendering everywhere.
Marketing & content sites
Statically generated pages that ship as HTML and rebuild on content change, so nothing waits on a client bundle to become readable.
SaaS dashboards with SSR
Server-rendered dashboards where the first paint carries real data instead of a loading skeleton.
App Router migrations
Moving a Pages Router or client-only React app to the App Router, route by route, without a rewrite freeze.
Streaming & partial rendering
Slow data sources isolated behind Suspense boundaries so the rest of the page renders immediately.
API routes & server actions
Backend logic that lives next to the pages it serves, without standing up a separate API service.
Rendering performance rescue
Routes rendering client-side that should be server-rendered or static, profiled and fixed: measured before and after.
How Next.js projects run here
A practical Next.js process, from rendering audit to production.
We keep the Next.js process structured but lightweight, so rendering strategy gets decided early and the build runs against that decision instead of discovering the wrong one after launch.
Audit & rendering strategy
We read the existing routes or the requirements, then decide server rendering, static generation or client rendering per route before writing page code.
Week 1
Routing & data design
App Router structure, layouts and data fetching: the decisions that determine whether a page is fast on the first visit, not just after it hydrates.
Week 1–2
Implementation & integration
Build or refactor routes, wire them to your data sources, and handle loading, error and not-found states with the framework’s own conventions.
Sprint by sprint
Testing, hardening & rollout
Automated tests on critical routes, Core Web Vitals and accessibility passes, then a staged release.
Pre-launch
Ongoing support & features
A standing team continues to ship routes and keeps Next.js and its dependencies current across major version upgrades.
Post-launch
Where Next.js earns its keep
Next.js use cases we most often deliver.
Most of our Next.js work sits where rendering strategy has a direct business cost: pages that need to rank, pages that need to load instantly, or both at once.
SEO-critical marketing pages
Statically generated or server-rendered pages built to be crawled and indexed correctly the first time.
SaaS product UI
The logged-in surface of a subscription product, server-rendered where the first paint needs real data.
Content-heavy sites
Blogs, resource centres and documentation generated at build time and revalidated on a schedule.
Legacy SPA migration
Replacing a client-only React app with the App Router, page by page, recovering the search visibility a pure SPA cannot get.
The stack around Next.js
The Next.js stack we typically use at QalbIT.
We usually pair Next.js with TypeScript and a data layer chosen per route: server components fetching directly, client components using TanStack Query where interactivity needs it, so rendering strategy stays a deliberate choice all the way down the stack.
Core
- Next.js 16
- TypeScript
- Next.js App Router
- Turbopack
State & data
- TanStack Query
- Zustand / Redux Toolkit
- REST & GraphQL
- Zod validation
Styling & design systems
- Tailwind CSS
- Radix UI primitives
- Storybook
- Design tokens
Quality & observability
- Vitest / Jest
- Playwright
- ESLint & Prettier
- Sentry
We adapt to what you already run. If your team already has a rendering strategy or a different data layer, we work inside it rather than rewriting for preference.
Next.js in production
Where the rendering strategy did the work.
The same discipline on every build: server rendering or static generation chosen per route rather than applied as a blanket default, and the client owning the code.
