Space

Space is a Shopify theme by Brickspace Lab ($320). Tested on 2026-11-08 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 79 for mobile speed and 91 for desktop speed, 92/92 for SEO and 83/81 for accessibility (mobile/desktop, 0–100). Those are medians across its 5 tested presets; mobile speed across every tested page ranges from 55 to 99. On its marketplace it is rated 4.8 out of 5 from 23 reviews. Note: its demo home page is heavy — 15.3 MB — heavier than a typical store, so the speed score may understate the theme.
