Southpaw
Southpaw is a Framer theme by Timotius Muliawan ($20). Tested on 2026-09-14 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 30 for mobile speed and 53 for desktop speed, 100/100 for SEO and 86/86 for accessibility (mobile/desktop, 0–100). Note: its demo home page is heavy — 6.3 MB — heavier than a typical store, so the speed score may understate the theme.
