Acero

Acero is a Webflow theme by Templates ($129). Tested on 2026-09-25 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 70 for mobile speed and 96 for desktop speed, 91/91 for SEO and 89/89 for accessibility (mobile/desktop, 0–100). Note: its demo home page is heavy — 10 MB — heavier than a typical store, so the speed score may understate the theme.
