Astryx
Open source design system built for people and AI agents
Visit astryx.atmeta.com ↗What is Astryx?
Astryx is an open source design system developed at Meta over eight years, now powering 13,000+ internal apps. It provides 150+ accessible React components, customizable theming, dark mode support, and ready-to-ship templates as a cohesive system. Built on React 19+ and StyleX, it requires no build plugins or styling library adoption.
Designed for both human developers and AI assistants to work with identical tooling, Astryx emphasizes composable internals, styling flexibility (compatible with Tailwind, CSS modules, or plain CSS), and theme customization through CSS custom properties. The project includes a CLI, comprehensive documentation, and Storybook examples to support rapid development.
