Why we choose Astro for high-performance sites

Most marketing sites ship megabytes of JavaScript they never use. Astro lets us send almost none — and the performance gains are not subtle.

01 / 05

Zero JS by default

Astro renders your components to static HTML at build time and ships zero JavaScript unless you explicitly ask for it. For a landing page or institutional site, that means the browser does far less work before the page is usable. We only hydrate the handful of components that truly need interactivity — a menu, a form, a carousel — and leave the rest as plain HTML.

02 / 05

Islands, not monoliths

The islands architecture lets us mix frameworks and ship interactivity in isolated chunks. A GSAP animation, a React widget, and a Vue form can coexist on the same page, each loading independently. Nothing blocks the first paint, and a heavy component never drags down the rest of the page.

What it means for clients

Faster load times directly improve conversion and SEO. On every Astro project we've shipped, we hit Lighthouse performance scores above 95 without micro-optimizing. That headroom lets us focus on design and content instead of fighting the framework.

Built for content teams

Astro's content collections let us manage blog posts, case studies, and landing pages as type-safe data. Editors get a predictable structure, and we get compile-time checks that catch broken links and missing fields before they ever reach production. It scales from a five-page brochure site to a content hub with hundreds of articles without the architecture falling apart.

When we reach for something else

Astro isn't the answer for every project. A highly interactive app — a dashboard, a real-time tool, a multi-step product — is better served by Next.js. We pick the tool that matches the job, and for content-driven sites that need to load instantly and rank well, Astro wins almost every time.
