Deskreen

Deskreen is a utility that streams your current PC screen to other devices over a local network. It is similar to having a second monitor, but the "monitor" can be almost any phone, tablet, laptop or smart TV that has a web browser. The app itself is cross-platform and runs on Windows, Linux and macOS, while the receiving device needs nothing but a browser, so no additional software has to be installed on it. Deskreen is fairly easy to set up, and its settings are pretty basic while still enabling simple customization.

The program works via a Wi-Fi or local network connection between the two devices, so the smoothness of the picture depends on the quality of that local network; an Internet connection is not required. The connection is protected by end-to-end encryption, which can be a significant factor for people concerned about their information being leaked. The picture quality can be adjusted, and you can share either the entire screen or a single application window. To use a device as a true extended desktop rather than a mirror, a virtual display adapter (dummy plug) is needed. Video demos and tutorials are available to help you figure out the setup process.

Deskreen lets you use a phone, tablet or laptop as a wireless second screen or teleprompter by simply opening a web browser on it.

Features:

• Minimalistic interface design with clear navigation around the program
• Multiple devices can be connected at once or, if needed, limited to only a certain amount
• Flip screen mode for teleprompter use, handy for video creators and presenters
• QR code scan to make establishing the connection fast and uncomplicated
• Information on the connecting device's IP address, browser, as well as a session ID

To finish all of this up, Deskreen is a rather simple app in its nature that serves one straightforward goal, and it accomplishes it well. Screen sharing to a secondary device is useful in many situations, both work-related, such as presentations or extra workspace, and for everyday personal use. The Community Edition is free and open source under the AGPL-3.0 licence and is still actively developed on GitHub.
