OpenDeviceHub is a fast, open-source iOS Simulator replacement for Xcode 27 that restores the familiar single-window-per-device interface while adding features like precise scaling, command-line control, and support for foldable devices. It connects to Xcode's installed simulators, offers extensive device controls and input methods, and includes a self-updating, notarized macOS application with a command-line tool for scripting.
