Braid is SEEK Group's open-source, themeable design system, React components styled with vanilla-extract (CSS authored in TypeScript, extracted at build time), supporting multiple brand themes including APAC and a plain wireframe mode.
Playroom, its component sandbox, lets designers and developers experiment with real components together without a local dev environment, directly reducing the need for high-fidelity mockups before development even starts.
Developers wanting a real-world example of vanilla-extract in production, or teams needing genuine cross-brand theming (not merely light/dark) in one component library.
It ships runtime checks that catch incorrect component usage in development and strip out automatically in production builds, worth checking as a pattern for catching misuse early without a performance cost later.
SEEK's design system for its employment marketplace products, with detailed guidelines.
