Astro vs WordPress for a small business website

We built appbuff.net in Astro. In a local Lighthouse run on mobile, the home page scored 99 for performance, 96 for accessibility, and 100 in the other two categories. The whole site ships one 2.5 KB JavaScript file plus a few inline scripts, and every page is a plain HTML file sitting on a CDN.

That’s a good result, and it’s also the easy case. A developer edits this site, maybe a few times a month, and nobody books anything on it. Change any of those three facts and the Astro build grows: an editing screen, pages rendered on the server, a database. Most “Astro vs WordPress” pages skip that part, so this one starts there.

TLDR

Pick Astro for a small business site that should be fast, cheap to host and quiet to maintain. Staff who edit often get a CMS with an editing screen. Bookings, logins and memberships run on Astro pages rendered on the server with a database behind them, built for the site instead of installed from a plugin list. WordPress keeps one real edge: an owner can add a feature from a plugin in an afternoon without a developer.

Static site vs WordPress: what each one is

WordPress is a PHP application with a database. Each page is assembled from the database when someone asks for it, usually with a caching plugin in front so it doesn’t have to. You edit everything in the dashboard. W3Techs counts it on roughly four in ten of all websites.

Astro is a static site generator: it builds every page into HTML ahead of time. There’s no database behind a static Astro site, and no admin login on the public address. Content lives in files, usually Markdown, or comes from a CMS at build time. The Astro docs put the aim plainly: “Less client-side JavaScript to slow your site down.”

One worry comes up in every conversation about a newer tool: will it still be here in five years? In January 2026 the Astro team joined Cloudflare. The announcement says Astro “stays open-source and MIT-licensed” and keeps supporting deployment targets other than Cloudflare. That’s as close to an answer as anyone gets.

Speed

A static Astro page has nothing to compute when it’s requested. The server sends a file. By default Astro also sends no JavaScript unless a component needs it, and JavaScript is where most mobile slowness comes from.

WordPress can be fast. A lean block theme on good hosting with a caching layer is quick. The trouble is that speed on WordPress is something you keep earning: each plugin can add its own scripts and styles to every page, and the site slows down a few kilobytes at a time. Our guide on measuring a slow WooCommerce store shows how that happens on a store.

How much speed matters for ranking deserves care. Google’s page experience docs say “Core Web Vitals are used by our ranking systems”, and in the same place that Google “always seeks to show the most relevant content, even if the page experience is sub-par.” Speed helps you win among pages that are equally good answers. It won’t lift a weak page over a strong one.

Security and upkeep

This is the largest practical difference for a small business. Patchstack’s 2026 report counted 11,334 new vulnerabilities across WordPress core, plugins and themes in 2025. 91 percent were in plugins, and only 6 in WordPress core. 46 percent had no fix available from the developer when they were made public.

Read that carefully. WordPress core is in good shape. The risk lives in plugins, and a small business site with a form plugin, a page builder, an SEO plugin and a slider has four doors to keep locked. Somebody has to update them, check the site still works afterwards, and notice when a plugin stops getting fixes.

A static site removes most of that list. There’s no login page to guess passwords on and no database for a request to reach. What’s left is a short list of build tools that get updated on your schedule, not an attacker’s. The upkeep still exists, it’s just smaller, and what it costs to maintain an Astro site puts numbers on it.

Editing: where WordPress wins

Here WordPress is ahead, and it isn’t close. Anyone who can use a word processor can change a page in the block editor, add a post, and swap an image, the same afternoon, without asking anyone.

Astro out of the box has none of that. The Astro WordPress migration guide says it directly: WordPress uses an online dashboard, Astro uses a code editor. For a team where the owner wants to fix a typo at 10 p.m., that’s a real cost.

There are two ways to close the gap. A Git-based editor like Keystatic gives the site an admin screen that saves content back into the project files, with no database. Or WordPress stays on as a headless editor, and Astro pulls the posts through the REST API. Both work. Both are setup work a developer does once, and the first is the one we’d pick for a site edited weekly.

Bookings, logins and memberships

“Static” describes how most pages are served, not a limit on what the site can do. Astro can render chosen pages on demand, keep sessions for logged-in visitors, and read and write a database. The hosts sell that database next to the site: Netlify DB is Postgres from Neon, and Cloudflare has D1. The home page and service pages stay static and fast, and only the booking form or the members area runs on the server.

How each need usually lands:

• Bookings and appointments. A booking tool you already pay for gets embedded. A booking flow with its own rules is built with a database table and a few server routes.
• Memberships and gated content. Server-rendered pages behind a login, with sessions and a members table.
• A store with hundreds of products. WooCommerce or Shopify keeps the products, stock and checkout, and Astro draws the pages, as the Astro storefront guide explains.
• A busy blog with several writers. A headless CMS with an editing screen, so nobody touches code.

The honest trade is who adds the next feature. On WordPress, an owner can install a booking or membership plugin in an afternoon and pay its yearly licence. On Astro, the same feature is built to fit and quoted up front, with no plugin to keep patched. For a business that wants to keep tinkering on its own, that difference matters. For one that wants a site that stays fast and doesn’t need babysitting, it points the other way.

SEO is a wash, with one difference

Neither platform ranks a page. Titles, descriptions, headings, internal links, structured data and content quality decide it. Astro makes it easy to ship clean HTML and full control of the head. WordPress with Yoast or Rank Math gives a non-developer a form for every one of those fields.

The difference shows up over time. An Astro site stays as fast as the day it launched, because nothing gets added to it without someone writing code. A WordPress site drifts as plugins pile up. That drift is where Astro’s speed advantage really comes from.

How to decide

Answer four questions honestly:

1. How often does the content change? A few times a month suits Astro on its own. Every day suits Astro with a CMS, or WordPress.
2. Who makes the changes? A developer or one careful person suits Astro. A rotating team of staff needs an editing screen on either platform.
3. Does any visitor need to log in, book or pay on the site? Then the Astro build includes server pages and a database, or a store behind it. Budget for that part on its own.
4. Who will do the updates in two years? If nobody, a static site fails gracefully. A WordPress site with unpatched plugins doesn’t.

A typical small business site, a home page, five service pages, an about page, a contact form and a monthly blog post, comes out on the Astro side of every question. For that site our recommendation is Astro, with Keystatic if the owner wants to edit text themselves.

If you’re already on WordPress and the answers point to Astro, moving a WordPress site to Astro without losing rankings covers the redirects and the metadata. The Astro website service does the move for a fixed price from $1,500, and the finished site can run on free hosting.
