Meta open-sources Astryx: a customizable React design system built for AI agents
Astryx, Meta's internal design system now public, ships 150+ accessible, themeable React components with a CLI and StyleX‑based styling that any developer can drop into a project. Because the API, docs, and CLI are agent‑ready, AI coding assistants can scaffold UI exactly like humans, speeding up prototyping and reducing hand‑off friction.
