What is it?

DuoDesk lets a Mac, Windows PC, Linux machine and Android phone or tablet work as one setup. You can move the pointer off one screen edge onto another computer and keep typing there, extend a computer onto a tablet or another machine, open a single app from another computer in its own window, and share files, clipboard contents and notifications in both directions.

Android devices are full peers: the app can answer and make phone calls from the computer, read and reply to texts, browse photos and phone storage, use the phone camera as a webcam, and act as a touchpad or gamepad. Devices connect over the same Wi-Fi, a USB cable, Bluetooth LE, or a Wi-Fi Direct or hotspot link set up on demand. Pairing is done once with a code, and the project states it uses no account, telemetry or cloud relay.

The codebase is Electron for the app, with native helpers in Swift, C#, and C, and a Kotlin Jetpack Compose Android app. Some features need extra setup, such as Android wireless debugging or permissions on Wayland.

Things to know

  • Licensed under GPL-3.0, a copyleft license that requires derivative works to stay open source.
  • The apps are not code-signed, so macOS, Windows and Android ask you to allow them manually on first launch.
  • On Windows 11 with Smart App Control enabled, unsigned apps can be blocked with no way to run them short of turning that setting off.
  • The full Android app's notifications, texts and Accessibility features need wireless debugging or manual restricted-setting steps.
