Gain

Gain is a Shopify theme by UTD BV ($100). Tested on 2026-11-08 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 69 for mobile speed and 89 for desktop speed, 92/92 for SEO and 92/92 for accessibility (mobile/desktop, 0–100). Those are medians across its 5 tested presets; mobile speed across every tested page ranges from 63 to 77. On its marketplace it is rated 4.7 out of 5 from 81 reviews. Note: its demo home page is heavy — 50.3 MB — heavier than a typical store, so the speed score may understate the theme.
