WebView uses different browser engines on each platform to render web content:
Windows: Uses WebView2, which is based on the Microsoft Edge (Chromium) browser engine. This provides modern web standards support and consistent behavior with the Edge browser.
Android: Uses android.webkit.WebView, which is based on the Chromium browser engine. The specific version depends on the Android WebView system component installed on the device.
iOS and Mac Catalyst: Uses WKWebView, which is based on the Safari WebKit browser engine. This is the same engine used by the Safari browser on iOS and macOS.
