WordPress vs Next.js vs Astro in 2026: speed, price and SEO (an honest comparison)

Every comparison you find ends the same way: "it depends on your project". True, but useless. Here we are going to take a stand. We compare WordPress, Next.js and Astro on the four things that really matter — speed, price, SEO and maintenance — and we tell you which one to choose depending on what you have on your hands.

The table, no frills

WordPress vs Next.js vs Astro

• Speed out of the box · WordPress: Slow (depends on plugins and hosting) · Next.js: Very fast · Astro: The fastest for content websites
• JavaScript shipped · WordPress: A lot (plugins + theme) · Next.js: Just what is needed · Astro: Almost zero by default
• Hosting cost · WordPress: €15–40/month · Next.js: Cents · Astro: Cents
• Maintenance · WordPress: Constant (plugins, security) · Next.js: Minimal · Astro: Minimal
• Editor for non-technical users · WordPress: Excellent · Next.js: Requires a separate CMS · Astro: Requires a separate CMS
• Ideal for · WordPress: Blogs with daily editing · Next.js: Apps, dynamic areas, accounts · Astro: Corporate sites, landing pages, blogs

Speed: not comparable

WordPress serves PHP that queries a database and builds the page on every visit, plus the baggage of plugins and the theme. Next.js and Astro generate static HTML served from the edge: it arrives before WordPress has finished thinking. In our autopsy a home page went from 4.8 MB to 480 KB just by changing the technology. It is not that WordPress is badly built: it does a job (rendering live) that most websites don't need.

Between Next.js and Astro, for a pure content website Astro usually wins hands down on JavaScript shipped (zero by default). Next.js takes the lead back as soon as there is real interactivity.

Price: the "free" trap

WordPress is free to license and expensive to own. Adding up the full bill — managed hosting, premium plugins, maintenance, incidents — it comes to between €700 and €2,000 a year just to keep running. Next.js and Astro turn that around: a one-off investment (our Express plan starts at €600) and a recurring bill close to zero.

SEO: there is less difference here than they sell you

Let's be clear, because this is where the most hot air gets blown: SEO is not won by the technology, it is won by whoever does the work. WordPress with a well-configured Yoast ranks perfectly well. Astro and Next.js generate technical SEO (meta, canonical, sitemap, structured data) natively, without plugins, which removes friction and errors. And speed — where they do win — is a ranking factor. But migrating doesn't "boost" your SEO by magic: it preserves it (with properly done 301 redirects) and leaves you a cleaner base to grow from.

If someone promises you "first page of Google" just for migrating to Next.js, be suspicious. The migration protects what you have and removes dead weight; growth comes afterwards, from content and links. What we guarantee is that you don't lose rankings in the switch.

So, which one do I choose?

• Stay on WordPress if you publish daily, several people edit and the WordPress editor is non-negotiable for your team. But give it serious maintenance.
• Astro if your website is corporate, a services site or a blog: maximum speed, zero maintenance, minimal cost.
• Next.js if there are dynamic areas, user accounts, a configurator or application logic.

At WordNext we choose for you based on what your website needs — not on what is fashionable — and very often the honest answer is Astro for the simple stuff and Next.js for what grows.
