Expo is designed for incremental adoption. Start with a single React Native view inside your existing native app.
50+ libraries. Zero native config.
Camera, notifications, file system, sensors. Expo SDK libraries install into any React Native app. Config plugins handle all Xcode and Gradle changes automatically. No manual native file editing.
Add screens. Keep native code intact.
Embed a React Native view inside any Swift UIViewController or Kotlin Activity. Your existing native app architecture stays exactly as-is. You add new screens in React Native without touching the old ones.
OTA updates work in bare React Native.
EAS Update ships JavaScript fixes to production users without a new binary. It works with any React Native app, Expo-created or not. Add it to your existing setup in under 15 minutes.
You don't need to rewrite your app to add React Native. Expo's brownfield integration lets you render a React Native view inside any existing UIViewController or Android Activity. Ship one new screen this sprint. Add another next sprint. Migrate as much, or as little, as makes sense. Your existing native code keeps working exactly as before.
Installing a native library used to mean editing Podfiles, Info.plist, AndroidManifest.xml, and build.gradle by hand. Config plugins automate all of it. Add push notifications, camera access, or biometric auth to your bare React Native app with one install command. No native configuration. No broken builds after an Xcode update.
React developers already know the component model, hooks, and the JavaScript ecosystem. With brownfield integration, they can build new React Native screens that drop directly into your existing native app. Stop gating every mobile feature on iOS and Android engineer availability. Let your web team contribute, without anyone touching the native codebase.
