Tamagui

Tamagui is a cross-platform UI framework and styling system for React and React Native that enables developers to build high-performance applications with a single codebase shared across web and mobile platforms. It combines a universal style system with a powerful optimizing compiler that transforms styled components into efficient, platform-specific output, significantly improving runtime performance. The framework provides a superset of the React Native styling API, allowing developers to write styles once and have them work consistently across environments. Tamagui also includes a full UI kit with both styled and unstyled components, enabling flexible design system creation. Its compiler performs advanced optimizations such as CSS extraction, tree flattening, and dead code elimination, reducing bundle size and improving rendering speed. The system includes robust theming capabilities with support for design tokens, responsive props, and dynamic themes like dark mode.
