KittyFarm is a macOS app for developers who need to test mobile apps across multiple devices at once. It displays iOS Simulators and Android Emulators side by side in a single window on your Mac, so you can see how your app looks and behaves on different device sizes or operating systems simultaneously. A key feature is touch replication: when you tap or interact with one simulated device, the same input is sent to all the others at the same time. The app also shows device frames (bezels) that visually represent real phone shapes. Developers can build their iOS or Android project and deploy it to all the running devices at once, rather than installing and testing one at a time. It requires macOS 26 or later, Xcode 17, and the Android SDK if you want to include Android emulators. Building it from source requires a tool called XcodeGen to generate the Xcode project from a configuration file.
