Platform comparison

WordPress vs Astro:
what you stop running.

Quick answer

WordPress is one application that both edits and serves your site, extended by plugins you keep patching. Astro compiles your content into plain HTML pages a CDN serves - no database, no plugin layer, nothing to log in to on the public site. You give up installing features yourself, and publishing runs a build instead of being instant, because Astro is a framework, not a CMS. WordPress still wins when the site changes daily or a plugin is the business.

At a glance

What you'd notice running the site.

WordPress vs Astro
Editing day to day

WordPress

wp-admin and the block editor - familiar to almost anyone who has written for the web, alongside the update notices and plugin banners.

Astro

Astro ships no editor, so choosing one is part of the job: Markdown files in the repository, a git-based editor like CloudCannon or Keystatic that commits them for you, or a headless CMS the build reads from. Astro documents guides for dozens of them.
Getting a change live

WordPress

Hit publish and it's live that second. So is a plugin update that breaks the layout, which is the same speed working against you.

Astro

A save or a commit triggers a build and a deploy, so a change is live in minutes rather than instantly - and the current version keeps serving until the new one is built.
What the internet can reach

WordPress

The whole application: the login page, every plugin's code and the database behind them, on the same server that shows your homepage.

Astro

Pre-built files on a CDN. There is no database and no login on the site itself; if you add an editor, its login lives somewhere else entirely.
Monthly patching

WordPress

Core, theme and every plugin, each on its own maintainer's schedule. Auto-updates help, and occasionally break the site.

Astro

No plugins updating themselves. Astro does publish its own security fixes - the high-severity advisory in July 2026 didn't affect static builds at all - and they arrive as one dependency update a developer tests and deploys on purpose.
Speed

WordPress

Pages are assembled on every request unless a caching layer is added; heavy themes and page builders make good scores hard work. Roughly half of WordPress origins pass Core Web Vitals in the HTTP Archive's technology report.

Astro

Every page is already HTML before the first visitor arrives, and no framework JavaScript ships unless a component asks for it. Astro's own reading of the same field data puts its sites at 71%.
Recurring cost

WordPress

Free software, paid upkeep: managed hosting, security, backups, premium licenses and often a care plan - $100-$600 a month for a typical business site.

Astro

Serving the built site can cost nothing: on Cloudflare's free plan, requests for static assets are free and unlimited. You still pay for the domain, for a hosted editor if you want one, and for developer time when the site changes shape.
Adding a feature

WordPress

Install a plugin in minutes, often without a developer. Each one is more code to keep updated for as long as the site lives.

Astro

A developer builds it, or it comes from a service - forms, search, bookings. Anything interactive is an island: one component that ships its own JavaScript while the rest of the page ships none.
Ownership and lock-in

WordPress

Open source, and every host supports it. Your posts are portable; the way page builders and plugins store your layouts often isn't.

Astro

Astro is MIT-licensed and the output is plain HTML. Content sits as Markdown in your own repository, and the built site would keep serving from any static host with no Astro involved at all.
Finding help

WordPress

It runs about 40% of all websites, so freelancers, agencies and answers are everywhere - of very mixed quality.

Astro

A far smaller pool, and you need someone comfortable with JavaScript tooling. Astro moves quickly too - two major versions in 2026 - so upgrades are a standing job rather than a one-off.

Under the hood

For whoever signs off on the stack.

Compare the two stacks, row by row
Compare the two stacks, row by row
Language and extension model

WordPress

PHP. Behavior is extended through hooks and filters, mostly by third-party plugins and themes loaded at runtime.

Astro

TypeScript and .astro components, compiled by a Vite build. Extended by integrations declared in one config file, and UI components from React, Vue, Svelte, Preact, Solid or Alpine can be dropped into a page where it needs them.
Rendering model

WordPress

Server-rendered PHP per request; full-page caching comes from the host or a plugin.

Astro

Static by default: the whole site is HTML on disk after a build. A single route opts out with a `prerender = false` export when it genuinely needs a server.
Client-side JavaScript

WordPress

Whatever the theme and each active plugin enqueue, on every page that loads them.

Astro

None from Astro unless a component carries a `client:` directive, and then only that island hydrates. A `server:defer` island renders per request while the rest of the page stays cached.
Content and data model

WordPress

MySQL or MariaDB. Posts, pages and custom post types share one table; custom fields are key-value rows in postmeta.

Astro

Content collections: Markdown, MDX, JSON or YAML in the repository, or a loader that pulls from a CMS, API or database, each entry validated against a schema with types generated from it. Live collections fetch at request time when data has to be fresh.
Editing interface

WordPress

wp-admin is part of the same PHP application that renders the public site.

Astro

Not included. Either a git-based editor that commits Markdown to the repository, or a headless CMS - Sanity, Payload, Contentful, Storyblok and others have documented guides - read by a loader at build time.
Forms and other server work

WordPress

A plugin, running on your own server, storing entries in your own database.

Astro

A form service, or an on-demand route. Astro Actions handle typed form submissions, but a page that posts to one cannot be prerendered - so this is the decision that turns a static site back into a server.
Redirects

WordPress

Any permalink structure WordPress allows, plus a redirect plugin or server rules.

Astro

Declared in the Astro config. A plain static build emits meta-refresh pages; supported adapters write the host's own redirect rules instead, which is what a migration needs for real 301s.
Images, fonts and sitemaps

WordPress

Plugins: an image optimizer, an SEO plugin for the sitemap, another for web fonts.

Astro

Built in. astro:assets transforms images at build time with Sharp, the Fonts API self-hosts and preloads web fonts, and the sitemap integration is maintained by Astro itself.
Hosting

WordPress

Any PHP host, from shared plans to managed WordPress platforms. WordPress asks for PHP 8.3+, MariaDB 10.11+ or MySQL 8.0+ and HTTPS.

Astro

Any static host or CDN for a prerendered build. On-demand routes need one of the four official adapters - Cloudflare, Netlify, Vercel or Node.
Security posture

WordPress

Core, themes and plugins patch independently. Patchstack counted 11,334 new vulnerabilities in the ecosystem in 2025, 91% of them in plugins and themes; WordPress core itself had 6.

Astro

One dependency tree. Astro has its own advisories - CVE-2026-59731, a high-severity authorization bypass, was fixed in 6.4.8 in July 2026, and static deployments without middleware were not affected - and since 6.0 a Content Security Policy can be emitted for static and on-demand pages alike.
Release cadence and support

WordPress

WordPress 7.0 "Armstrong" shipped in May 2026, and core's compatibility promise means old themes and plugins usually keep working across releases.

Astro

Astro 6.0 arrived in March 2026 and 7.0 in June, each with breaking changes, and the core team backports security fixes to one previous major only. Staying supported is somebody's job about once a year.
License

WordPress

GPLv2 or later.

Astro

MIT.

The honest part

When WordPress is still the right call.

  • You publish every day.

    A build sits between saving and being live. If the rhythm is publish, spot a typo, publish again, that minute of waiting is friction you'll feel every day.

  • Marketers rebuild pages on their own.

    Page builders let non-developers redesign layouts. An Astro site can offer block-based editing through a CMS, but a developer builds the blocks first.

  • A plugin is your business.

    Bookings, memberships, courses, a directory - if one plugin runs it and nothing replaces it cleanly, rebuilding it rarely pays back.

  • The site is cheap and you patch it yourself.

    Under about $30 a month, a handful of plugins, and an hour of real attention each month - a migration takes years to pay for itself.

And when we wouldn't pick Astro either

  • Several writers, drafts and approvals.

    Astro has no opinion about editorial workflow, so all of it comes from whatever CMS you bolt on. If publishing is the business, start from the CMS instead of adding one later.

    Better fitA modern CMS

  • Visitors log in.

    Accounts, gated content and dashboards are an application. Astro can render those routes on demand, but then you own a server and its patching again - the thing you were trying to stop.

    Better fitAn app framework

  • It's an online store.

    Checkout, payments and card compliance shouldn't depend on a build step, or on us being available the day a gateway changes.

    Better fitA commerce platform

  • Nobody will own the repository.

    A built site needs someone or something to run the build when content changes. If no developer and no CMS will ever do that, one account that holds the whole site is the more honest answer.

    Better fitA hosted site builder

FAQ

WordPress vs Astro, straight answers.

  • For a site that changes a few times a month, usually yes: the pages are pre-built, there is no plugin layer to patch, and hosting costs close to nothing. For a site that publishes daily, sells online, or depends on a plugin nothing else replaces, WordPress or a proper CMS is the better answer. The site decides, not the framework.

  • Yes, though not in wp-admin. Astro is a framework rather than a CMS, so the editor is a choice: Markdown in the repository for developer-run sites, a git-based editor like CloudCannon or Keystatic for everyone else, or a headless CMS such as Sanity or Payload. Saving triggers a build, so changes go live within minutes.

  • Not in the WordPress sense. It has integrations - official ones for sitemaps, MDX and the four deployment adapters - plus UI components from React, Vue or Svelte wherever a page needs interactivity. They are dependencies in your own repository that a developer updates deliberately, not code that installs itself and then keeps updating itself in production.

  • Nothing, if the move is done properly. Every old URL is mapped to a 301 before cutover, configured at the host rather than as meta-refresh pages, and titles, meta descriptions and structured data come across with the content. We watch Search Console afterwards. Speed usually improves too, which helps rather than hurts.

  • Often nothing. The built site is files on a CDN, and on Cloudflare's free plan requests for static assets are free and unlimited. Add on-demand routes, a form endpoint or a hosted CMS and you pay for those - usually a few dollars a month, against $100-$600 for managed WordPress hosting, security and a care plan.

  • It removes the plugin layer, where 91% of 2025's 11,334 WordPress vulnerabilities were, and a pre-built site exposes no database or login for anyone to reach. Astro itself still ships security fixes: a high-severity bypass was patched in July 2026, though static builds were unaffected. Someone still has to own those updates.
