Astryx: Meta's agent-ready design system, open source
Meta open-sourced the React 19 + StyleX design system behind 13,000 internal apps: 150+ accessible components, themes and a CLI, built for humans and AI coding agents alike.
Why it matters
The design system that powers Meta's own apps, now open source and explicitly built so coding agents can generate on-brand UI from the same tokens designers use.
What you could build with it
A startup building a design tool could fork Astryx's component layer and let its coding agent generate on-brand UI from the same tokens its designers use, instead of hand-wiring a component library.
Does it hold up?
Battle-tested inside Meta across 13,000 apps, with npm packages and docs public, but still in beta: expect API churn before pinning it in production, and the charts packages are canary-only.
