This gets argued as a technology question. It is really a question about who touches the site after launch.
WordPress is right when publishing is the point
If non-technical people publish several times a week, WordPress earns its place. The editing experience is familiar, the plugin ecosystem covers most requests without custom work, and hiring someone to maintain it is easy anywhere in the world.
Its costs are equally real: plugins are third-party code running on your site, each one a maintenance and security surface. Performance is achievable but not free — it is something you actively defend against every plugin added later.
Next.js is right when the site is closer to an application
When the site has to do things — authenticated areas, real-time data, complex flows, tight integrations — a framework designed for applications stops fighting you.
You get speed by default rather than by maintenance, a single language across front and back, and rendering choices per page: static where content rarely changes, server-rendered where it must be fresh. The cost is that changing the site usually requires a developer.
The combination worth knowing about
Headless WordPress keeps the editor your team already knows and renders the front end with Next.js. Editors get their familiar admin; visitors get a fast site.
Be honest about the trade: it is two systems to maintain instead of one. Worth it when both requirements are genuinely non-negotiable, over-engineering when only one is.
Questions that decide it
- How often does content change, and by whom? Daily by non-developers points to WordPress. Occasionally, or by developers, points to Next.js.
- Is this a website or an application? If users log in and do things, you are building software.
- How much does speed matter commercially? If you sell through the site, it matters more than it feels like it does.
- Who maintains it in two years? Choose what your actual team can run, not what is most interesting to build.
The honest summary
Neither choice is a mistake in the situation it suits. The mistake is choosing on preference rather than on who edits the site and what it has to do — and then spending two years paying for it.
