The web framework built for speed.
Astro takes a radical approach: Zero JavaScript by Default. Every other mainstream framework ships JS whether a page needs it or not. Astro doesn't — and that single decision is why our sites load in under a second.
Three ideas, one fast website.
Astro isn't fast by accident. It's a small set of deliberate architectural choices that add up.
Static-First Rendering
Every page is compiled to plain HTML and CSS at build time. There's no server rendering a template on every request, and no client-side framework rebuilding the DOM before a visitor sees anything.
Islands Architecture
Interactive components — a form, a carousel, a filter — hydrate independently as small 'islands' of JavaScript, only when and where they're actually needed. The rest of the page stays static HTML.
Content Collections
Blog posts, case studies, and structured content live as type-safe Markdown files in your Git repo. No database, no CMS login screen, no external service that can go down or raise its prices.
What that means for your website.
Every one of these traces back to Astro's static-first, zero-JS-by-default design.
Images That Don't Slow You Down
Every image is automatically converted, resized, and lazy-loaded. Up to 60% smaller files with no manual work and no quality loss.
Built to Rank on Google
Clean HTML, fast load times, and perfect Core Web Vitals scores mean search engines can crawl and rank your content from day one.
Simple, Durable Upgrades
No breaking major-version migrations every year. Astro's static-first model ages well — a site built today still works the same way in five years.
Astro vs the alternatives.
A practical comparison of what building with Astro means versus a typical WordPress or Webflow site.
| Feature | Delivr Studio Built with Astro | WordPress | Webflow |
|---|---|---|---|
| Core Web Vitals | Built to pass | Often fails | Mixed results |
| Page load (mobile) | < 1 second | 4–8 seconds | 2–5 seconds |
| Time to Interactive | < 1 second | 3–6 seconds | 2–4 seconds |
| Monthly platform fees | Free | Paid hosting required | Paid plan required |
| Lighthouse score | 90–100 target | 40–70 | 60–85 |
| JavaScript shipped | 0% by default | Heavy | Moderate |
| Content ownership | Full — Git repo | Partial | Platform-locked |
| Build time | 3–4 weeks | 4–8 weeks | 3–6 weeks |
Lighthouse scores reflect typical results for Astro builds. Other figures are illustrative comparisons, not per-project measurements.
