Benchmark repository for different React Native styling libraries.
iPhone 17 Pro running iOS 26.0 in Release mode. Result after opening the app for the second time (cached by the OS).
Uniwind, NativeWind 4 and NativeWind 5 use the exact same classNames.
It’s difficult to directly compare Unistyles, Uniwind, and NativeWind to StyleSheet, as it has no features, it only serves as a baseline for performance.
