Meta has open sourced Astryx, a StyleX-based design system marketed as an alternative to shadcn/ui.

The screenshots highlight 150+ accessible React components, full type-safe theming, and 8 years of internal use across 13,000 apps at Meta. The launch positions Astryx as a more complete design-system release rather than just another component library.
