Next.js vs WordPress: which should a business website be built on?

The comparison that actually matters

Both can produce a good-looking website. The differences show up after launch — in what the site scores on Core Web Vitals, how often it needs patching, and what happens the first time you need something the theme did not anticipate.

Where WordPress still wins

• A team publishing several posts a week who will never call a developer to do it.
• A site whose value is a large content archive with taxonomies, authors and editorial workflow.
• A budget where the difference between a themed build and a custom one decides whether the project happens at all.
• An existing WordPress site that works, ranks and is maintained. Replatforming a healthy site is a cost with no return.

Where it stops being the right answer

The pattern is consistent. A business installs a theme, then eleven plugins to make the theme do what the business needs. Each plugin adds JavaScript, a database table and an update that can break the others. Two years later the site takes four seconds to load, nobody dares update anything, and the fix quoted is a rebuild.

The second failure is custom logic. A quoting calculator, a dealer login, a product configurator, an integration with your ERP — every one of these is either a plugin that almost fits or custom PHP nobody else will maintain. In Next.js they are just code, written the way the rest of the application is written.

What about editing?

This is the objection worth taking seriously, and the honest answer is that WordPress is better at it out of the box. A Next.js site needs a CMS attached to match it. Done properly — content in a headless CMS, editors working in a normal admin interface — the day-to-day experience is comparable, and the site stays fast because the content is rendered at build or request time rather than assembled by plugins on every visit.

Total cost over three years

A themed WordPress build is cheaper on day one. Over three years the comparison usually inverts: managed hosting, plugin licences, monthly maintenance and the eventual performance rescue add up, while a Next.js site of the same size runs on cheap infrastructure and needs a dependency bump every few months. A marketing site with SEO configured starts around $399 with us and is typically two to four weeks of work.

How to choose in one question

Ask what the site is for. If it is a publication, WordPress. If it is the front door of a business that will eventually need custom behaviour — a calculator, a portal, an integration, an AI assistant — start on Next.js and skip the rebuild you would otherwise pay for in year two.
