Astryx is Meta's open-source design system engineered for both human engineers and AI coding agents. Powered by StyleX and React, it brings over 150 accessible, production-tested primitives, pre-built application templates, and a zero-runtime CSS footprint. Standout capabilities include dedicated AI chat composers, rich streaming text primitives, design tokens with instant multi-theme swapping, and an agent-first CLI that scaffolds and swizzles components directly into your repository.
