QBridge is a modern, lightweight native bridge for iOS that lets you build hybrid apps using idiomatic Swift, while exposing only the native APIs you explicitly choose to JavaScript.

It is designed as a clean, native-first alternative to Cordova and Capacitor, without legacy constraints, global magic, or opaque runtime behavior.

Qbix, the company behind QBridge, designs web-first applications. Get in touch if you need help or would like to collaborate with us. We've released our entire module platform as open-source to help developers. You're welcome:

There is no polling, no hidden lifecycle, and no background JavaScript runtime.

Cordova and Capacitor try to hide native. QBridge embraces native and makes it safe.

Swift:

let webView = WKWebView(frame: .zero)
QBridge.shared.attach(to: webView)

JavaScript:

window.webkit.messageHandlers.QBridge.postMessage({
  service: "DeviceBridgePlugin",
  action: "info",
  args: [],
  callbackId: "cb1"
});

window.QBridge = {
  onNative(payload) {
    console.log(payload.data);
  }
};

Swift:

@objc class MyPlugin: QBridgeBaseService {
  @objc func hello(_ args: Any?, callbackId: String?) {
    bridge.sendEvent(callbackId ?? "", data: ["message": "Hello from Swift"])
  }
}

The plugins below are production-grade, written in idiomatic Swift, and designed to solve real problems in hybrid apps. Like continuing to use the same storage Web APIs you're already used to (IndexedDB and localStorage) but have them actually continue to work in your app. Use the same code on the Web and in your app!

They are listed in order of importance.

🕴"It would be a shame if your app's storage was suddenly deleted."

QBridge is intentionally small, explicit, and honest.

If you want predictable storage, strong security, App Clips support, and clean Swift-native plugins, QBridge is the modern choice.
