Astro vs WordPress for marketing sites: an honest comparison

"Should we build on Astro or WordPress?" is one of the first questions on a new marketing site project. Both can produce a good website. They are just optimized for different things, and picking the wrong one costs you either speed or convenience. Here is the honest version, without the framework tribalism.

What each one actually is

WordPress is a content management system that has run a large share of the web for two decades. You install a theme, add plugins for features, and edit everything in an admin dashboard. It is mature, flexible, and familiar to almost everyone.

Astro is a modern web framework that ships fast, lightweight pages by default. It sends mostly static HTML with very little JavaScript, which is exactly what a marketing site wants. It is custom code, so it is built by a developer rather than assembled from plugins.

The comparison at a glance

Dimension	Astro	WordPress
Speed / Core Web Vitals	Fast by default	Needs caching & tuning
Technical SEO	Clean, lightweight HTML	Good, with the right setup
Security	Minimal surface, static	Plugins are a common target
Maintenance	Very low	Ongoing updates needed
Editing for non-devs	Needs a headless CMS	Built in, very easy
Plugin ecosystem	Smaller, code-first	Huge, for almost anything
Cost over time	More upfront, less to run	Cheaper start, adds up
Best for	Performance-critical marketing sites	Content-heavy sites edited daily

When Astro is the better call

Astro is the right choice when performance and craft matter and the site does not change every single day. That covers most company and product sites: a startup raising a round, a brand that wants to load instantly and rank, a conversion-focused marketing site where every tenth of a second affects the result.

• Speed is a feature. Astro ships static HTML, so pages are fast without caching plugins. That helps both conversion and SEO.
• Less to break. No plugin stack to update, no database to harden. Fewer moving parts means fewer security holes and less maintenance.
• Custom, not assembled. The design is built exactly as drawn, not bent to fit a theme.

When WordPress is the better call

WordPress earns its place when a non-technical team publishes constantly and needs full control without a developer in the loop.

• Daily publishing. A news site, a busy blog, or a large team adding pages every day benefits from the familiar editor and instant publishing.
• Plugin shortcuts. Need a specific membership, forum, or directory feature fast and cheap? There is probably a plugin for it.
• In-house familiarity. If your team already knows WordPress and that is a hard requirement, fighting it rarely pays off.

The honest middle: Astro plus a headless CMS

The "but my team needs to edit it" objection is the main reason people default to WordPress, and it is solvable. Pair Astro with a headless CMS (such as Sanity, Storyblok, or Contentful) and your team edits content in a friendly dashboard while the site stays fast and static. You get WordPress-style editing without the plugin bloat and security exposure. For most of the marketing sites we build, this is the sweet spot.

The framework rarely decides whether a site succeeds. The strategy, the design, and the speed do.

The bottom line

If your marketing site needs to be fast, secure, and low-maintenance, build it on Astro, and add a headless CMS if your team edits often. If you run a content operation that publishes daily and lives in WordPress already, WordPress is a reasonable, pragmatic choice. Either way, the cost question matters as much as the framework one, so it is worth reading what drives website pricing before you decide. And if the project is more app than pages, that is a different conversation entirely.
