Every Capwrapper build ships with 40 native bridges already compiled into your app. You do not install plugins, configure SDKs, or write native code. The bridges cover everything from camera and GPS to push notifications, biometrics, in-app purchases, and analytics — and the same JavaScript API works identically on iOS and Android.
Detecting Capwrapper in your code Before calling any native bridge, check whether your web app is running inside Capwrapper or in a regular browser. This lets you build progressive enhancements that degrade gracefully on the web.
if ( window . isNativeApp ) { // Running inside AppWrapper — native features available // window.platform is either 'ios' or 'android' } else { // Running in a regular browser }
Use window.platform to branch between iOS- and Android-specific behavior when needed.
If you use an AI builder (Base44, Bolt, Lovable, Cursor, or Replit), paste any code snippet from this guide and describe the feature you want to add. The AI can implement the full integration for you.
Three activation tiers All 40 bridges are compiled into every build. How you unlock each one depends on the tier.
Automatic 7 features work from the very first launch with zero configuration and zero code.
Activate with code ~32 features activate by adding a JavaScript snippet to your web app.
Needs external setup ~11 features require an external account or a file on your domain. Capwrapper handles the app-side integration.
