The storefront itself: every page of Magento Open Source rendered as plain HTML with the web platform doing the work. HTMX refreshes the parts that change, native dialogs, details and forms replace the widgets, and the whole page ships about 23 KB of JavaScript. Strict Content Security Policy, WCAG 2.2 AA, WebP images, RTL.
The demo store's home page.
What it does
Home, category, product, search, cart, account and CMS pages, all server-rendered
Private content (cart counter, welcome, messages) through HTMX fragments, so pages stay in the full-page cache
Tailwind v4 build that reads the enabled modules and includes their styles
Child themes, compat modules for third-party extensions, a component library at /zero/ui/
