Open Source Android Screen Mirroring Apps

scrcpy is an application for displaying and controlling your Android device through USB connection (or over TCP/IP). It is cross-platform (GNU/Linux, macOS and Windows) and does not require any root access. scrcpy displays only the device screen but offers great performance (30~60fps) and quality (1920×1080 or above). It’s got low latency (35~70ms) and a very low startup time (less than a second). It offers plenty of great features and is non-intrusive, with nothing left installed inside the device. scrcpy works with Android devices with at least API 21 (Android 5.0) and adb debugging must be enabled on the device.

Weylus turns your tablet or smart phone into a graphic tablet/touch screen for your computer! No apps except a modern browser (Firefox 80+, iOS/iPadOS 13+) are required on your tablet. Start Weylus, preferably set an access code in the access code box and press the Start button. This will start a webserver running on your computer. To control your computer with your tablet you need to open the url http://<address of your computer>:<port set in the menu, default is 1701>, if possible Weylus will display to you the url you need to open and show a QR code with the encoded address. If you have a firewall running make sure to open a TCP port for the webserver (1701 by default) and the websocket connection (9001 by default).
