J-Cut

J-Cut is a Framer theme by NS. Studio (Free). Tested on 2026-10-26 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 73 for mobile speed and 95 for desktop speed, 100/100 for SEO and 98/98 for accessibility (mobile/desktop, 0–100). Note: its demo home page is heavy — 14.1 MB — heavier than a typical store, so the speed score may understate the theme.
