Download Deskreen – Turn Any Device into a Secondary Monitor Over WiFi

Deskreen is a free, open-source desktop screen sharing tool that turns any device with a web browser — a tablet, smartphone, old laptop, or smart TV — into a secondary monitor for your computer. It works over your local WiFi network with no additional hardware, cables, or accounts required.

Simply run Deskreen on your main computer, open the generated URL in a browser on your secondary device, and your desktop or a specific application window will appear on that screen. The connection is end-to-end encrypted using WebRTC, ensuring your screen content stays secure on your local network.

Deskreen is perfect for extending your workspace using devices you already own — you can display a reference document on your tablet while working on your main monitor, or stream your desktop to a TV for a presentation. It is lightweight, setup-free, and works with virtually any modern browser.
