Meet Deskreen - an open source app that turns any device with a web browser into a secondary screen for your computer. Built with web technologies and ElectronJS so it is cross-platform. It supports Windows, MacOS and Linux.
Why I made Deskreen?
It all started with me wanting to use my iPad as a secondary screen for my Macbook. But I found that it is already outdated to use 'Sidecar' - a MacOS built in feature for that purpose. I tried upgrading both of them, but it didn't help. The only option left was to buy a new iPad and even new Macbook, which I did not want to do. I also have a Windows PC and sometimes I need to use my iPad as second screen for it as well.
I tried to look for FREE solutions on internet, but I could not find anything that would fit my expectations. Besides, all methods using free software for screen sharing I found, were different for Windows, Mac and Linux. I got very confused about it. Then I got an idea of creating Deskreen.
I decided to make it free and open-source to help people to solve this problem. Deskreen works the same for Windows, MacOS and Linux.
