WordPress or Astro in 2026: which to choose for your site?

WordPress is a dynamic CMS (PHP + MySQL) that generates pages on demand. It powers 43% of the global web (W3Techs, 2026), offers an ecosystem of 60,000 plugins, and suits sites with frequently updated content. Astro is a 'static-first' JavaScript framework: it generates static HTML pages at build time, with no client-side JavaScript by default. Result: pages 3 to 5× lighter than WordPress.

The choice depends on your context. WordPress excels for blogs, e-commerce sites (WooCommerce) and non-technical teams managing content daily. Astro is built for showcase sites, high-performance landing pages and projects where technical SEO and speed are priorities.

An Astro site sends little or no JavaScript to the browser: it starts with a structural advantage on Core Web Vitals, especially LCP (Largest Contentful Paint). A WordPress site loaded with plugins on shared hosting has to be optimized to reach the same thresholds. Measure your own site on PageSpeed Insights rather than relying on an average. On mobile the gap is often wider: less JavaScript = faster startup on slow connections.

WordPress can reach good scores with premium hosting (Kinsta, WP Engine), a CDN and specific optimizations (WP Rocket, Imagify). But these optimizations carry a recurring cost (€200 to €500/year) and technical complexity. With Astro, most of these optimizations are built in, but a static site still has to be checked (images, fonts, third-party scripts).

Both platforms can reach the top of Google. But Astro offers a structural advantage on Core Web Vitals, a ranking factor since 2021. An Astro site generates pure HTML immediately indexable by Googlebot, with no dependency on client-side rendering. WordPress, with heavy themes, can create client-side rendering issues that delay indexing of certain content.

On the other hand, WordPress has mature SEO plugins (Yoast, RankMath) with a graphical interface, ideal for non-technical teams. Astro requires manual configuration (meta tags, sitemap, robots.txt, JSON-LD) or specialized libraries. This is something I handle systematically in my projects.

A WordPress site has a median build cost of €5,000 in France, and €10,000 or more for a quarter of projects (La Fabrique du Net barometer, 1,312 real budgets, 2026). Hosting and maintenance (updates, backups) come on top. At WebConsulting, an Astro site is rented for €490 + €39/month (Foundation, 1 page), i.e. €1,894 over 3 years, or €890 + €69/month (Acceleration, 5 pages), i.e. €3,374 over 3 years, hosting, maintenance and domain included. For a showcase site, cost depends mostly on the provider's model, not the technology.

WordPress has a lower opportunity cost if your team manages content itself: the admin interface is accessible without technical training. Astro requires a developer for structural changes.

WordPress accounted for 95.5% of the infected sites Sucuri handled in 2023 (Sucuri report), a reflection of its popularity as much as its fragility. Of 11,334 WordPress vulnerabilities discovered in 2025, 91% came from plugins and 9% from themes (Patchstack). Without regular maintenance (weekly updates, firewall, monitoring), a WordPress site can be compromised quickly.

A static Astro site has no database, no PHP, no exposed admin interface: the attack surface is near-zero. Maintenance is limited to hosting renewal and quarterly framework updates.

Choose WordPress if: your team publishes content daily without a developer, you run a high-volume blog or a WooCommerce store, or your project needs complex plugin-based features. Choose Astro if: your site is primarily a showcase or landing page, performance and SEO are priorities, or you want the lowest possible maintenance cost.

My default recommendation for showcase sites and SMBs: Astro. For e-commerce and non-technical editorial teams: WordPress with premium hosting. In both cases, check my bespoke website creation service for a choice tailored to your context.
