SimUtil

A terminal UI for launching Android Emulators / iOS Simulators
Launch, connect, manage your devices and more — all from the terminal

Browse your available emulators and simulators side-by-side, launch with custom options and connect to physical devices wirelessly.

Simutil is written with Nocterm, a terminal UI framework for Dart with similar syntax to Flutter.

Features

• One-Key Launch — Start any device with Enter, no need to open Android Studio or Xcode
• Android Launch Options — Provide launch option for Android Emulators: Normal, Cold Boot, No Audio, or Cold Boot + No Audio,...
• Shutdown device — Shutdown simulators/emulators.
• Logcat — View logcat output of Android emulators / devices, support filtering.
• ADB Tools Built-in — Connect to physical Android devices wirelessly:
  • Connect via IP address
  • Pair with 6-digit code (Android 11+)
  • QR code pairing (Android 11+)
• Custom Plugins — Add your own external tools (scrcpy, Maestro, etc.) via a YAML file, no code changes needed. Press p to pick a plugin and a command to run on the selected device.
• Edit Config — Press e to open ~/.simutil/settings.yaml in your default editor (macOS, Linux, Windows).

Custom Plugins

SimUtil can run external shell-command tools (scrcpy, Maestro, custom scripts, …) defined in the plugins: section of ~/.simutil/settings.yaml — no code changes needed. A default file (with theme, last_selected_device_id, and scrcpy) is created automatically on first launch.

Each plugin groups one or more commands. In the app, press p on a selected device to choose a plugin, then a command. Press e to edit the config file. A command can also define a single-key shortcut to run it directly. Commands are filtered to the selected device, and args support template variables like {device.id} and {device.name}.

# ~/.simutil/settings.yaml

        args: [-s, "{device.id}"]
        platforms: [android]   # android | ios; empty = any
        requires_running: true # only show when the device is running
        mode: detached         # detached (default) | inherit
        shortcut: s            # optional single key to run directly
