What is it?

QtScrcpy shows an Android device's screen on a Windows, macOS, or Linux computer and lets you control it with mouse and keyboard. It connects over USB or over the network and does not require root privileges. Nothing is installed on the device itself.

The project is a C++ and Qt rewrite of the scrcpy project, using FFmpeg for video encoding and OpenGL for rendering. It supports features such as screen recording, screenshots, drag-and-drop APK installation and file transfer, bidirectional clipboard sync, and controlling multiple devices at once. Custom keyboard-to-touch mapping scripts let you play touch-based games with a keyboard and mouse.

The requirement is Android 5.0 (API 21) or later, with ADB debugging enabled on the device. Prebuilt packages are available for Windows and macOS, and the project can be built from source with qmake or CMake.
