1,303 Astro themes have Lighthouse scores as of 2026-11-11. Every theme is re-tested on a schedule set by its popularity — the most used every week, the long tail every one to two months — and every run is kept, so a theme's page shows its history. New themes are picked up from the marketplaces daily.

Lighthouse's accessibility score covers the automatable part of WCAG 2 — colour contrast, alt text, form labels, ARIA use, heading order, keyboard focus — and a theme scoring 90 or better on it starts a store close to compliant; no automated test covers everything, so ADA compliance also needs a manual review. In November 2026, 3dinterior by Tarik @Nearmelab scores highest at 100 out of 100, and 1,129 Astro themes reach 90 or better.

Each theme's own demo store is run through Google's PageSpeed Insights API (Lighthouse) on a simulated mobile phone and on desktop, for the home page and, on store platforms, a collection page and a product page. A theme's score is the median of its presets; a preset's is the mean of its pages. Dead, password-protected and cloaked demos are excluded before they can score. The full method is at /methodology.
