Dellen

Dellen is a Framer theme by Sidebay Supply ($79). Tested on 2026-10-13 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 85 for mobile speed and 99 for desktop speed, 100/100 for SEO and 100/100 for accessibility (mobile/desktop, 0–100). Note: its demo home page is heavy — 11.6 MB — heavier than a typical store, so the speed score may understate the theme.
