Targeted at web developers using React and Next.js, core advantages are Apple-inspired aesthetics, 60fps performance, easy installation (npm or git clone), and zero JavaScript runtime overhead. Typical use cases involve creating stunning web interfaces with glass effects for various websites and applications. The library is open-source and free, with no pricing model.
