Tamagui

Tamagui v2.0.0-rc.41 is a UI library and optimizing compiler for React (web and native). It provides a design system with styled components, theming, and responsive props, aiming to reduce bundle size and runtime overhead through compile-time optimizations. Released as release candidates since 2023, it requires React 19 and offers deep integration with React Native. Key differentiators include its compiler that transforms styled components into optimized CSS or native code, and its cross-platform support without platform-specific code forks.
