Websites that score 100 on Core Web Vitals

We build and rebuild sites in Astro — minimal JavaScript, content-first, ready to rank. Faster pages, cleaner code, measurably better Core Web Vitals.

The problem: heavy sites lose rankings and sales

Most modern sites ship a large bundle of JavaScript to the browser for things that could be plain HTML. The browser downloads it, parses it, and runs it before the page becomes usable. On a mid-range phone that means slow loads, layout that jumps as things appear, and inputs that lag.

Google measures this directly with Core Web Vitals — Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint — and uses them as a ranking signal. A page that fails CWV is harder to rank and converts worse, because visitors leave before it finishes loading. React, Next, and a plugin-heavy WordPress install commonly land in the 29-45 range on a real mobile test.

The solution: a content-first Astro build

Astro renders your pages to clean, static HTML at build time and ships almost no JavaScript by default. Interactive bits are added only where they are actually needed, instead of hydrating the whole page. The result is a site that paints fast, holds its layout, and responds instantly.

Every build ships SEO-ready out of the box:

Astro was acquired by Cloudflare in January 2026 — the framework is well-funded, actively maintained, and a safe long-term foundation, not a fad.

Proof, framed honestly

We ran a pilot rebuild of one of our own pages in Astro. On a Lighthouse mobile test it scored 100/100 for performance, with a Speed Index around 2.3 seconds, zero render-blocking JavaScript, and a Cumulative Layout Shift of 0.

You can open the live result and run your own audit on it:

To be clear about what this is and isn't: 100 is a Lighthouse lab score on that page, on that test. Real-world numbers depend on your hosting, your content, and the integrations you need (a checkout, a chat widget, an embedded map all add weight). What we can honestly promise is a dramatically lighter, faster, better-structured site than a typical JS-heavy build — and we'll show you the before/after numbers on your pages. No fake metrics, no "guaranteed #1 on Google."
