Linux users can choose between an .AppImage or .deb file. If you’re running Arch ( or derivates ), Deskreen is available in the AUR.



Check out the video below to see how Deskreen works. The video is a youtube nocookie embed. If you wish to watch it on invidious, follow this link.



1.  250MB of RAM memory is needed on average to run Deskreen with one screen sharing session. Every additional screen sharing session will need up to 100MB of extra memory on average for a smooth performance.

2. Any modern CPU should be able to handle Deskcreen. From a dual core to a 1 core ARM cpu ( such as on a Raspberry Pi )

3. If you want to have a full secondary screen experience with Deskreen you will need a Virtual Display Adapter.

A Virtual Display Adapter is not needed if you only want to mirror your screen or share a single application window.

What is a Virtual Display Adapter? It’s a small plug that looks similar to a USB flash drive and, when plugged in, tricks your computer into thinking that an external display was connected. They’re generally pretty cheap and available everywhere.

4. Deskreen uses screen recording technology to live stream your computer screen to your tablet, phone. You will need to grant Screen Recording Permissions on your computer:

  • macOS System Preferences > Security & Privacy > Privacy > Screen Recording > Allow Deskreen by selecting it in the list of apps
  • Windows you will need to  add ‘Private Network Access’ for Deskreen on first start or in firewall settings
  • Firewalls, antivirus etc Deskreen is not yet code signed ( an issue of funds ). That means your antivirus will complain when you run Deskreen for the first time. You should add an exception for Deskreen. Also Firewalls both on your computer and WiFi router should not block any Deskreen network access and activity.
