Expo

Expo is a platform and framework for building universal React Native applications, providing tools for development, building, and deploying to iOS, Android, and web.

Key Features

• Expo SDK: Comprehensive APIs for device capabilities
• EAS Build: Cloud-based native app builds
• EAS Submit: Automated app store submissions
• Over-the-Air Updates: Push updates without app store review
• Expo Router: File-based routing for React Native

Core Capabilities

Expo's managed workflow handles the complexity of native development—you write JavaScript/TypeScript while Expo manages native code, builds, and signing. EAS Build compiles your app in the cloud, eliminating the need for local Xcode or Android Studio setups.

For vibe coders entering mobile development, Expo dramatically lowers the barrier to entry. You can go from idea to App Store submission without ever opening Xcode. Companies like Shopify, Coinbase, and Discord use Expo.
