A Next.js development company that has shipped the hard parts

Next.js changed shape substantially, and a lot of what is written about it is stale. Server components, the caching model, and the rendering defaults all work differently than the tutorials most agencies learned from, and the failure mode is subtle: the app works in development, then behaves strangely in production because something was cached at a layer nobody thought about.

We build on this stack continuously and publish what we learn, including the parts that are awkward. That is the real qualification here. Anyone can scaffold a project; the value is in knowing which rendering strategy a page should use and why, and being able to explain the answer to whoever maintains it after us.

The most common production problem we are called in for is not performance, it is unpredictability: a page showing stale data, an admin screen serving another user’s content, a revalidation that never fires. Almost always the cause is a caching decision nobody made deliberately, inherited from a default that changed between versions.

We decide rendering and caching per route, write the reasoning down, and make invalidation explicit rather than hoping a timer covers it. It sounds like bookkeeping. It is the difference between an app you can reason about and one where every bug report starts with "but it works locally".

Rebuilding a WordPress site on Next.js is straightforward. Doing it without losing organic traffic is the actual job, and it is mostly unglamorous inventory work: every indexed URL enumerated, mapped to its new home, tested before launch, and monitored after. Sites lose serious traffic to migrations, and it is almost never the framework’s fault.

We treat the redirect map as the deliverable that matters, validate it against real crawl data rather than a sitemap that may itself be wrong, and stage the cutover so it can be rolled back. Then we watch rankings for a month, because that is when problems surface.

Next.js is our default because it covers the most ground: rendering flexibility, a real backend, and a hiring pool. But it is not always the answer. A brochure site with five pages does not need it. A heavily interactive internal tool with no SEO requirement might be simpler as a plain React app. A content site your marketing team owns end to end might genuinely be better on a hosted platform.

We will tell you when that is the case, including when the honest answer is that your existing WordPress site is fine and the money is better spent on content. Recommending the smaller option costs us a project and buys the kind of trust that produces the next one.
