Meta open-sources Astryx design system for developers and AI assistants
Meta has open-sourced Astryx, a customizable React design system currently in beta and built on React 19 or later and StyleX. The project README says it includes more than 150 accessible components, theming, dark mode, templates, typed React components, and CLI tooling designed for both developers and AI assistants. Meta also claims the system grew internally over eight years and now supports more than 13,000 apps.
Astryx combines a substantive component library with typed APIs, documentation, and CLI tooling intended to give developers and AI assistants a shared interface-building workflow.
