Streamline
Streamline is a Shopify theme by Archetype Themes ($420). Tested on 2026-11-07 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 78 for mobile speed and 89 for desktop speed, 95/95 for SEO and 92/91 for accessibility (mobile/desktop, 0–100). Those are medians across its 3 tested presets; mobile speed across every tested page ranges from 61 to 99. On its marketplace it is rated 4.8 out of 5 from 334 reviews. Note: its demo home page is heavy — 8.9 MB — heavier than a typical store, so the speed score may understate the theme.
