Sage is Kajabi's design system for its course-creation and online-business platform, documenting type, color, icons, a 12-column grid, and components written in both Rails and React with matching Figma files.
It's strongest as a reference for a creator-economy SaaS product specifically, useful for anyone building tools for course creators or online educators, an audience Sage's components (frames, layouts, interactive patterns) are tuned for directly.
Designers and developers building creator-tool or course-platform products who want a real system built for that exact domain, with code available on GitHub.
Components ship in both Rails and React implementations at once, worth checking which matches the target stack before adopting patterns directly.
Kajabi's own design system — the principles and components behind its platform.
