239 BigCommerce themes have Lighthouse scores as of 2026-09-15. 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 September 2026, Bamboo Bend by Arctic Leaf scores highest at 100 out of 100, and 129 BigCommerce 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.
