Astro vs WordPress: which one for a business website?

The core difference

WordPress is a content management system backed by a database. Every page is assembled on the server from a theme, plugins and database records. That makes it flexible: thousands of plugins, a familiar admin, WooCommerce for stores. According to W3Techs, roughly 40% of all websites run on WordPress.

Astro is a framework that builds your site into ready-made HTML pages ahead of time, at publish. The browser gets HTML and CSS, plus JavaScript only for interactive pieces like a form or calculator. Astro’s docs call this the “islands” architecture: by default a page ships no client-side JavaScript at all.

Every other pro and con follows from that difference.

Side by side

	Astro	WordPress
Page speed	Very fast out of the box	Depends on theme, plugins and hosting
SEO foundation	All content in HTML, full control over markup	Good with an SEO plugin, but duplicates creep in easily
Security	No database or plugins — little to attack	Needs regular core and plugin updates
Editing	Headless CMS: comfortable, but has to be set up	Familiar admin many editors already know
E-commerce	Small catalogs, via external services	WooCommerce is mature
Hosting	Often free (Cloudflare Pages, Vercel)	Paid, needs PHP and a database
Maintenance	Almost none	Updates, backups, plugin management
Developer pool	Smaller, needs a front-end developer	Large, easy to hire

Speed and SEO

Google uses Core Web Vitals in its ranking systems. Good thresholds: LCP under 2.5 seconds, INP under 200 ms and CLS of 0.1 or less.

An Astro site passes these almost automatically: each page is prebuilt HTML served from a CDN. You can build a fast WordPress site too, but it takes a lean custom theme, few plugins, caching and decent hosting. In practice most WordPress sites run heavy themes and page builders, so they’re slow.

Astro also gives developers full control over markup: headings, schema, canonical tags, hreflang. On WordPress the same is handled by plugins, and if you’re not careful you end up with duplicate archive, tag and attachment pages.

Security and maintenance

Most WordPress compromises happen through vulnerable plugins and themes. That means regular updates, backups and plugin audits — an ongoing maintenance cost.

An Astro site has no database and no server code running per page. Leave it alone for six months and nothing happens to it. For a small business without an in-house developer, that matters.

Editing experience

WordPress’s strength is an admin many content editors already know. With Astro you connect a headless CMS such as Keystatic, Decap or Sanity, where pages and posts are edited in a visual editor. For editors the difference is small, but it has to be part of the project.

If you have a large editorial team, many authors and complex permissions, WordPress may be the more comfortable choice.

When to choose Astro

• Service businesses, corporate sites, landing pages, blogs and docs.
• Speed, rankings and low cost of ownership matter.
• No in-house developer to keep up with updates.
• Content changes a few times a week, not every hour.

When to choose WordPress

• An online store with payments, shipping and inventory — WooCommerce.
• Your team already works in WordPress and doesn’t want to switch.
• You need a specific feature that exists as a proven plugin.
• A large editorial team with roles and a complex publishing workflow.

Already on WordPress?

Don’t rebuild a working site just for the technology. Start by checking speed and technical health: often removing unnecessary plugins, replacing a heavy theme and setting up caching is enough. If the site runs on a page builder, is slow and breaks after updates, migrating to Astro with the same design and 301 redirects usually pays for itself through better rankings and lower maintenance.

Bottom line

Astro is the best fit for most service-business sites, landing pages and blogs: fast, secure and cheap to run. WordPress is for stores, complex functionality and teams already invested in it. Choose the platform by the job and the cost of ownership over the next 2–3 years, not by your vendor’s habit.
