Expo
Expo is an open-source framework for apps that run natively on Android, iOS, and the web. It builds on top of React Native, providing a curated set of tools and libraries (SDK) to simplify the development lifecycle.
When to Use
- Building React Native apps without managing Xcode/Android Studio projects manually.
- Needing fast Over-the-Air (OTA) updates via EAS Update.
- Rapid prototyping with the Expo Go app.
- Teams that prefer a "Managed" workflow but still need native capabilities (via Config Plugins).
Quick Start
# Create a new app with Expo Router (default in 2025)
npx create-expo-app@latest my-safe-app
cd my-safe-app
npx expo start
