Con Radius Design is a Next.js development company. We build and migrate websites and web apps on Next.js, with server rendering so pages arrive finished rather than assembled in the browser. We work with Payload CMS or with the backend you already have, and we hand the project over instead of renting out developers.
Why Next.js rebuilds disappoint
Next.js is a good decision for most content-driven sites. The disappointments usually come from how the rebuild is run, not from the framework.
The rebuild loses the rankings.
Old URLs get replaced instead of redirected, internal links are rewritten from memory, and the traffic that paid for the old site leaves with it.
The page still renders in the browser.
Next.js can server-render, but a project that fetches everything client-side ships an empty shell. Crawlers and AI systems get nothing to read, and the framework gets the blame.
The build is over-engineered.
A brochure site does not need an application architecture. Complexity that nobody asked for is paid for twice: once at build time and again at every change.
Nobody can edit anything.
Without a content model and reusable blocks, every text change becomes a developer ticket and a deployment.
What you get
Process
What we do
Migration and redesign
Moving an existing site to Next.js without losing search rankings. Every old URL that carries traffic or links gets a redirect, verified as a single hop to a working page.
Custom web development
Websites and content-driven web apps with server-side rendering and static generation, built from reusable blocks.
Performance and Core Web Vitals
Rendering strategy, image handling and font loading tuned against field data, not against a lab score alone.
Headless CMS integration
Payload CMS as the default, or an existing backend such as Contentful, Storyblok, Sanity or WordPress used headless.
Search and AI visibility
Structured data, clean heading hierarchy, sitemap, llms.txt and passages written so they can be quoted in AI answers.
Support and maintenance
Framework updates, monitoring and content changes as a retainer or on request.
If you are weighing the stack: Headless CMS agency covers the content side of the same setup. WEESS case study is a live example you can open, and All case studies has the rest. If the question is visibility in AI answers, GEO agency goes into that. Either way, Contact is the short route.

How a project runs
Four stages. After the first one you know the scope and the price.
Inventory and scope
We map your existing pages, URLs and traffic before designing anything. Output is a page list, a URL map and a fixed scope.
Content model and build
Blocks, templates and the Next.js front end, visible on a preview environment while it is being built.
Migration and launch
Content moves over, redirects are set for every old URL, and each one is verified as a single hop before the switch.
Measure and maintain
Rankings, Core Web Vitals and enquiries are compared against the state before launch. Ongoing support is optional.
Who this fits, and who it does not
Next.js is not automatically the right answer. It pays off under specific conditions.
| Criteria | Fits | Does not fit |
|---|---|---|
| You are replacing a site that has become slow, fragile or impossible to extend. | — | |
| Search visibility matters to your business, so the rebuild must not cost you rankings. | — | |
| Your team publishes content and should not need a developer for routine changes. | — | |
| You want one partner for the front end, the CMS and the search side, rather than three. | — | |
| A handful of pages that rarely change would do. | — | |
| The site is to stay in Webflow and only needs looking after. | — | |
| The site already works and only visibility is missing. | — |
We do not rent out developers by the month. If you need staff augmentation for an existing in-house team, another provider fits better and we will say so.
One price for the build, an optional monthly rate for ongoing work. EU business customers are invoiced under the reverse charge procedure.

Frequently asked questions
A Next.js development company builds websites and web apps on the Next.js framework, decides the rendering strategy per page, connects the backend or CMS, and migrates existing sites onto the new architecture. Con Radius Design does this with Payload CMS as the default backend, or with the system you already run.
Yes, and the migration is the part that decides whether the project pays off. We map every existing URL before the rebuild, redirect each one that carries traffic or links to its closest new equivalent, and verify after launch that every redirect resolves in a single hop to a working page. A redirect that lands on a missing page has the same effect as deleting it.
No. Next.js makes good search performance possible because pages can be rendered on the server and delivered complete. It does not create it. The gains come from the rendering strategy, the content itself, the internal linking and a migration that keeps the existing URLs alive.
No. We take on projects with a defined scope and hand them over. If you need staff augmentation for an existing team, a provider specializing in that fits better.
A build or migration starts at 3,000 EUR one-off and reaches around 8,000 EUR for larger sites, depending on page count, languages and functionality. Ongoing support starts at 350 EUR per month and is optional. You get the scope and the price before the build starts.
