MinimalDev
MinimalDev is a Astro theme by Anton Liberant (Free). Tested on 2026-09-13 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 93 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 light — 92 KB in 7 requests — where a stocked storefront is usually 1–4 MB, so the speed score flatters it.
