What is Next.js development?
Next.js development is building websites and web applications with Next.js, a React framework that can render pages on the server, generate them in advance as static files, or render them in the browser. Each page gets the approach that suits it, which makes sites fast to load and easy for search engines to read.
We use Next.js when one product has to do two jobs: public pages that need to rank and load quickly, and a logged-in area that behaves like an application. The App Router, server components and API routes let one codebase handle both, with authentication from Auth.js, Clerk or Auth0. This website is built on Next.js.
For a purely internal tool with no public pages, plain React with a separate API is often simpler. For a site that is mostly content, a CMS does most of the work and Next.js only renders it. We pick the simplest tool that will hold up.
- How long does your main page take to load on a phone?
- Can search engines read the pages that matter?
- Can your team update content without asking a developer?
How a Next.js build runs
Content, URLs and search visibility are planned before the first page is built.
1. Review
We look at what the site has to achieve, who edits it, current speed and search performance.
2. Plan
Page list, content model, rendering approach, timeline and cost, approved by you before the build starts.
3. Build in short cycles
Working pages on a preview link every cycle, with content entered by your team as it is ready.
4. Run in parallel
For replacements, the new site runs on a preview address while redirects and content are checked against the old one.
5. Go live and train
Launch with redirects, sitemaps and monitoring in place. Editors are trained on the CMS.
6. Support and improve
A named support contact, speed and search checks, and new pages or features as you need them.
Why Next.js projects underdeliver
Next.js gives you many ways to render a page. Picking the wrong one, or ignoring the content side, undoes most of its benefit.
Wrong rendering choice
Everything rendered in the browser, so pages load blank, search engines see little and the framework's main advantage is lost.
Heavy pages
Large images, unused scripts and oversized bundles make a fast framework feel slow on mobile.
Content locked in code
Every text change needs a developer and a deployment, so the site goes stale.
SEO left to the end
Titles, metadata, structured data and sitemaps added after launch, if at all.
Auth bolted on
Login added late, with protected pages and API routes checked inconsistently.
Locked to one host
Built around platform-specific features with no plan for moving to your own cloud if costs or data rules change.
What we build with Next.js
Each build starts from what the site has to achieve for the business, then picks how each page is rendered.
- 01
Company and service websites
Fast, search-friendly sites with clear structure, metadata, sitemaps and structured data built in.
- 02
CMS-driven sites and catalogues
Content and product catalogues your team edits in a headless CMS, published without a developer.
- 03
Web apps with public and private areas
Customer portals, booking flows and dashboards behind login, sharing one codebase with the public site.
- 04
Education platforms
Course pages, student and teacher areas and AI assistants on one platform.
- 05
Authentication and roles
Login with Auth.js, Clerk or Auth0, role-based access and protected API routes.
- 06
Migration to Next.js
Moving an older site or React app to Next.js page by page, keeping URLs and search rankings intact.
How each page should be rendered
Most Next.js sites mix approaches. We choose per page, based on how often the content changes and who sees it.
| Page type | Rendering approach | Why |
|---|---|---|
| Home, service and about pages | Static generation | Fastest load, easy for search engines, rebuilt when content changes |
| Product or catalogue pages | Static with incremental revalidation | Fast pages that pick up CMS edits without a full rebuild |
| Search results and filtered lists | Server rendering | Fresh results that are still readable by search engines |
| Logged-in dashboards | Server components with client interactivity | Data loaded securely on the server, interactions handled in the browser |
| Forms and simple back-end tasks | Route handlers and server actions | No separate API needed for small jobs |
Ways to work with us
Pick the model that matches where your site or app is today.
| Model | Best when | How it is priced |
|---|---|---|
| Bottleneck review | A site is slow, hard to edit or losing search visibility | Fixed fee for a short, defined engagement |
| Defined build | Pages, content model and features are agreed and need building | Fixed scope, paid against agreed milestones |
| Managed team | You need a Next.js team for a set project and period | Monthly, based on the team composition you need |
We quote after the first conversation, once we know the scope. Every system is handed over with documentation and a named support contact.

Frequently asked questions
When public pages need to load fast and be found in search. Next.js renders them on the server or in advance, which plain React does not do on its own.
No. Vercel is the simplest option for many sites, but we also deploy Next.js on AWS, Google Cloud or Azure when cost, control or data rules call for it.
Yes. We connect a headless CMS such as Sanity, Strapi or Payload so your team updates text, images and products without a developer.
Not if it is planned. We keep or redirect every URL, carry over metadata and check the new site before switching.
Auth.js when you want to keep users in your own database, Clerk or Auth0 when you want a managed service with less to maintain.
Yes. The Algon website, including this page, is built with Next.js.
Yes. Public pages and a logged-in area can share one Next.js codebase, components and deployment.
