“Should we use Next.js or WordPress?” is a question I’ve been asked four times this month. Half the time it’s the right comparison. Half the time it’s the wrong one. Here’s how to tell which.
What each one actually is
WordPress is a content management system. It’s a database, an admin interface for editing content, and a templating system that turns content into HTML pages. It runs on PHP. About 43% of the web uses it.
Next.js is a JavaScript framework for building web applications. It’s not a CMS — it has no admin interface, no built-in content editor, and no opinion about how you store data. You can build a content site with it, but you’ll need a separate CMS (often a headless WordPress, Sanity, or Contentful) to manage the content.
That difference matters. The honest comparison isn’t “Next.js vs WordPress” — it’s “Next.js plus a headless CMS vs traditional WordPress.”
When WordPress is the right answer
WordPress wins when:
- You’re a content-heavy business — a marketing site with regular publishing.
- Your team includes editors but no engineers.
- Your budget is under $20,000 for the build.
- You want any developer to be able to maintain the site five years from now.
- Your traffic is below 500K monthly visits and Core Web Vitals scores are merely “good,” not “perfect.”
This is most US small and mid-sized businesses. WordPress is boring, well-understood, and good enough for the work it needs to do.
When Next.js (with headless WordPress or another CMS) wins
Next.js wins when:
- Your site has real product functionality — dashboards, interactive tools, complex user flows — alongside content.
- Performance is competitive moat. Sub-1-second page loads matter for conversion.
- You have engineers on staff who’ll maintain it.
- Your budget is $25,000+ for the build.
- You want maximum flexibility on the front-end without giving up a usable CMS for editors.
Most SaaS marketing sites, high-end editorial publishers, and product-heavy businesses end up here. The combination is more expensive but the ceiling is much higher.
The performance question
Yes, Next.js sites can be faster than WordPress sites. They’re not automatically faster. A well-built WordPress site with proper caching, image optimisation, and a sensible theme will outperform a poorly-built Next.js site every time.
What Next.js gives you is a higher performance ceiling. With static generation or incremental static regeneration, page loads can be near-instant. CDN edge caching, image optimisation, and code splitting are built in. If you’re investing seriously in conversion-rate optimisation, that ceiling matters.
For a typical content site that gets 30K visits a month, the WordPress version will load in 1.2 seconds and the Next.js version will load in 0.6 seconds. Both are fine. The difference doesn’t justify the cost gap.
The lock-in question
WordPress has lock-in too — to PHP, to the WordPress ecosystem, to plugins. But it’s a 20-year-old, well-documented lock-in. Anyone can pick up a WordPress site and work on it.
Next.js sites lock you into a JavaScript build pipeline that changes faster. The Next.js you write today won’t run cleanly in five years without updates. The headless CMS you chose may not exist in five years. Engineers are more expensive and more specialised.
That doesn’t mean don’t use Next.js. It means: build it if you have the team to maintain it. Don’t build it because it’s the trendy answer.
What we recommend
For US small businesses: WordPress, almost always. Custom-coded if budget allows, page-builder if it doesn’t. Our WordPress build comparison walks through that decision.
For mid-market B2B and SaaS: depends. If your engineering team is going to own the site, Next.js with headless WordPress is excellent. If a marketing team is going to own it solo, traditional WordPress is the safer call.
For high-end editorial and complex product sites: Next.js with whatever CMS your editors prefer. The investment makes sense at this scale.
If you’d like our help thinking through which is right for your specific situation, our custom build service handles both, and we’ll tell you honestly which one your project needs — even if it’s the cheaper option.
