Meta open-sources its biggest design system

🔥 What happened Meta just open-sourced Astryx, a design system that grew internally for eight years and now powers 13,000+ apps. It ships 150+ React 19 components, seven themes, and a CLI explicitly designed for AI agents to use alongside humans. 💡 Why it matters The largest design system inside Meta was invisible to the outside world — until now. Engineers get the same tooling humans and agents share, plus swizzle to eject component source into your own repo. No styling lock-in: Tailwind, CSS modules, or plain CSS all work. ⚡ Our take This isn't another component library drop — it's Meta's answer to shadcn, with docs written for agents from day one. If you're letting agents build UI, Astryx deserves a serious test drive.
