Miro
Miro is a Shopify theme by Noord ($320). Tested on 2026-09-29 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 71 for mobile speed and 95 for desktop speed, 97/97 for SEO and 95/96 for accessibility (mobile/desktop, 0–100). Those are medians across its 5 tested presets; mobile speed across every tested page ranges from 60 to 85. Note: its demo home page is heavy — 8 MB — heavier than a typical store, so the speed score may understate the theme.
