Spark SaaS
Spark SaaS is a Astro theme by Andrei Alba (Paid). Tested on 2026-10-09 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores – for mobile speed and 100 for desktop speed, 100/100 for SEO and 97/97 for accessibility (mobile/desktop, 0–100). Note: its demo home page is light — 165 KB in 7 requests — where a stocked storefront is usually 1–4 MB, so the speed score flatters it.
