⚡ Write Native with TypeScript ✨ Best of all worlds (TypeScript, Swift, Objective C, Kotlin, Java, Dart). Use what you love ❤️ Angular, React, Solid, Svelte, Vue with: iOS (UIKit, SwiftUI), Android (View, Jetpack Compose), Flutter and you name it compatible.
NativeScript is a hybrid mobile app framework that allows developers to build truly native iOS and Android apps using JavaScript, TypeScript, or Angular. Unlike frameworks that rely on WebViews, NativeScript provides direct access to native APIs, ensuring apps perform like native applications. It is ideal for developers who want the convenience of JavaScript while leveraging full native functionality.
