- How ReMOAT provides sub-10ms peer-to-peer DevTools for any iOS browser.
On iOS, Apple mandates that all third-party browsers (including Google Chrome, Firefox, and Microsoft Edge for iOS) must use the WebKit rendering engine under the hood. Consequently, bugs appearing in Chrome for iOS are almost always WebKit bugs identical to mobile Safari. In this comprehensive guide, we compare all methods for inspecting iOS web browsers across Mac, Windows, and Linux.
1. Why Chrome on iOS is Actually Safari (WebKit)
Due to Apple App Store guidelines, Google Chrome on iOS is powered by Apple's `WKWebView` engine rather than Google's Chromium/Blink engine. This means: - JavaScriptCore executes all scripts (not V8). - CSS rendering adheres strictly to WebKit standards. - You can inspect Chrome on iOS tabs using Apple Safari Web Inspector or ReMOAT!
2. Debugging iOS Browsers from Windows / Linux with ReMOAT
If you do not own a Mac, you cannot use Apple Web Inspector. ReMOAT bridges this gap: 1. Inject the lightweight ReMOAT SDK (`<script src="https://sdk.remoat.dev/remoat-sdk.js"></script>`). 2. Open the page on iPhone (Safari or Chrome). 3. Connect from your Windows or Linux PC via 6-digit PIN. 4. Enjoy a live, interactive Chrome on macOS DevTools interface over WebRTC!
