Islands architecture
Only the interactive components become dynamic. The rest of the page stays static HTML, so the browser has less work to do.
Why Astro
Fast by design, not as a plugin afterwards.
Most websites are slow because they send too much JavaScript to the browser. Astro flips that order around: it builds your page on the server into HTML and sends JavaScript only where interaction is really needed. That makes Astro a fast and safe alternative to WordPress for content-driven sites.
The core
Less JavaScript, more speed.
Since 2021 Astro has been built around one principle: fast by default. Pages are static HTML by default, and interactive parts become isolated islands that load their own JavaScript. The rest of the page stays light.
Little JavaScript, by default
Astro sends no JavaScript by default. That keeps load times low and helps the Core Web Vitals, without you having to optimise afterwards.
Content collections
Your content (blog, cases, pages) gets a schema that is checked during the build. You see errors straight away, not only in production.
Server islands
You render personal or dynamic parts separately on the server, while the rest of the page stays static and cacheable.
Imageoptimisation
Astro optimises images at build time into modern formats, so pages are lighter without manual work.
View Transitions and i18n
Smooth page transitions and multilingual support are part of the framework, with type-safety from content to routes.
Bring your own framework
Write in .astro, or use React, Vue, Svelte or Solid alongside it. Astro loads their runtime only where you place an interactive island.
Deploy at the edge
Through adapters the same site runs on Cloudflare, Node or another host. This demo runs on Cloudflare, close to the visitor.
Astro 7
Built for speed, in the build too.
Astro 7 was released on 22 June 2026 with speed as its theme. The old Go compiler has been replaced by a new Rust compiler, and together with Vite 8 and the Rolldown bundler builds are 15 to 61% faster, according to Astro's own benchmarks. Some content-heavy sites build more than twice as fast.
In January 2026 the team behind Astro joined Cloudflare. Astro stays open source and MIT-licensed, and keeps running on multiple platforms, not just on Cloudflare. AstroBuild itself runs on Astro with the Cloudflare adapter.

"Rust compiler + Vite 8 + Rolldown"Comparison
Astro next to WordPress and a traditional CMS.
Astro generally delivers faster websites that are safer to maintain than WordPress, while WordPress is stronger for non-technical editors and ready-made plugin ecosystems. WordPress is the most used CMS in the world: it powers 41.5% of all websites (W3Techs, June 2026). Powerful and accessible, but its model differs fundamentally from a content-first stack. A fair comparison:
| Aspect | Astro | WordPress | Traditional CMS (Drupal, Joomla) |
|---|---|---|---|
| Model | HTML-first, JavaScript only where needed | PHP and database, assembled on every visit | PHP and database with modules or extensions |
| JavaScript to the browser | Little to none, by default | Often a lot, via themes and plugins | Variable, often a lot |
| Performance | Fast by design (static HTML, edge) | Heavily dependent on hosting, caching and plugins | Dependent on configuration and caching |
| Attack surface | Minimal: no public database or plugin layer on a static build | Large: third-party plugins are the biggest source of vulnerabilities (7,966 in 2024, Patchstack) | Smaller than WordPress, but still a server plus modules |
| Maintenance | No mandatory plugin or security rounds on a static site | Ongoing core, theme and plugin updates | Periodic core and module updates |
| Hosting | Static or edge (CDN, e.g. Cloudflare), cheap to scale | Requires a PHP and MySQL server | Requires a PHP and database server |
| Managing content | Markdown or Git, or a headless CMS | Built-in editor, strong for non-technical editors | Built-in editor with workflow and permissions |
| Scalability | Static scales trivially on a CDN | Scaling requires caching and server work | Scaling requires server and database tuning |
| SEO and findability | Fast, semantic HTML by default | Very possible, but often via plugins | Very possible, often via modules |
| Learning curve and ecosystem | Requires web knowledge, modern and growing ecosystem | Accessible, huge plugin ecosystem | Steeper, powerful for complex sites |
The cells marked green show where that approach generally stands strongest. No single stack wins on every front.
Fair
When WordPress or a CMS is the better choice.
- Editors without technical knowledge who want to change everything themselves, with a familiar editor and instant preview.
- Ready-made ecosystems such as a web shop, membership management or a forum, where an existing plugin offering saves years of work.
- A team that has worked with WordPress or a CMS for years and does not want to throw that knowledge away.
Astro excels at content-driven sites where speed, findability and low maintenance matter: marketing sites, blogs, documentation and landing pages. For those profiles it is rarely the wrong choice.
Frequently asked questions
Astro vs WordPress, answered briefly.
Is Astro a good alternative to WordPress?
For content-driven sites where speed, findability and low maintenance matter, often yes. WordPress remains stronger for non-technical editors and ready-made plugin ecosystems.
Why is an Astro website faster than WordPress?
Astro delivers pages as static HTML and sends little to no JavaScript to the browser by default. Only the interactive islands load JavaScript, so the browser has less work to do.
Is Astro free?
Yes. Astro is open source and MIT-licensed. Since January 2026 the team has been part of Cloudflare, but Astro stays free and runs on multiple platforms.
When is WordPress the better choice?
When non-technical editors want to manage everything themselves, or when you need a ready-made ecosystem such as a web shop or membership management.
