Astryx is a fully customizable, open-source design system built by Meta, powering over 13,000 internal apps. Engineered for both human developers and AI coding agents, it features 150+ accessible React components styled with StyleX (with no build plugins required). What sets it apart is its "open-internals" architecture—allowing you to swizzle and extract full component source code—and strict API predictability that ensures LLMs and humans can build seamlessly together.
Curious how the "swizzle" workflow holds up when you want to upstream improvements back to the base library without conflicts.
How does the "swizzle and extract full component source code" feature actually work in practice, like does it pull in the full dependency tree or just the component itself?
Finally tried Astryx this morning and the swizzling out of a Button into my project was surprisingly painless, which is rare for design systems this big.
The swizzling into full source is genuinely useful, beats fighting a black box every time you need a tweak. Surprised how clean the StyleX setup is without a build plugin in sight.
