WebView App Development
One web app, inside a native shell, in both stores
We wrap your existing web app in a thin native container — App Store distribution without a second codebase.
Architecture
Native APIs as a type-safe bridge to the web layer
Push, biometrics, camera, geo — native capabilities reach React through a Promise-based bridge channel. No WebView-as-black-box.
We ship
Capacitor
When an existing web app needs a native shell for store distribution.
We ship
Custom bridge
When the native team contributes modules and the channel must be typed.
We ship
TWA · PWA
When iOS Safari is enough and Android runs through a Trusted Web Activity.
When WebView, when not
An honest capability matrix
WebView is the right answer when most user sessions run online anyway and you already own a web codebase. Here is the trade-off, plainly laid out.
Capability matrix · WebView · Hybrid · Native
Time-to-market
Weeks instead of months — one codebase is enough.
Offline-first
Without a SQLite layer, offline gets expensive quickly.
Push notifications
APNs / FCM run through the native shell.
Biometrics / Wallet
FaceID, TouchID, NFC — reachable via the bridge.
60fps animation
Complex custom drawing belongs in native.
Update velocity
Web layer ships without a store review.
