Switchback
Switchback is a Astro theme by Peachfin Themes (Paid). Tested on 2026-11-07 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 100 for mobile speed and 100 for desktop speed, 100/100 for SEO and 100/100 for accessibility (mobile/desktop, 0–100). Note: its demo home page is light — 91 KB in 8 requests — where a stocked storefront is usually 1–4 MB, so the speed score flatters it.
