What is it?

KittyFarm is a macOS app for viewing and controlling several iOS Simulators and Android Emulators from a single window. Touch input on one device can be mirrored to all the others at once, which helps when testing the same flow across multiple screen sizes or platforms.

iOS simulators are displayed live using private SimulatorKit APIs, so no screen recording permission is required. Android emulators are connected over gRPC. Device bezels are drawn from Apple's CoreSimulator chrome assets and Android SDK skins, and the layout scales each device to fill the available space.

The app also includes a Build & Play workflow that builds an iOS or Android project and deploys it to all connected devices in parallel. Devices can be reordered by dragging them. Building requires macOS 26 or later, Xcode 17 or later, and the Android SDK for emulator support.
