Mouse without Borders is a free application developed by Microsoft that allows users to control up to four computers from a single mouse and keyboard. It is designed to make it easier to use multiple computers at the same time, allowing the user to move the mouse pointer between multiple monitors and easily copy and paste text, images, and files between computers. The application also allows users to share a clipboard between computers, sync files, and share peripherals such as printers, speakers, and webcams. Mouse without Borders is compatible with Windows, Mac, and Linux operating systems.
spacedesk expands the screen to another computer instead of sharing a mouse and keyboard to control two computers
Borderless mouse often fails to disable mouse clicks on the slave machine, identification works fine every time
The borderless mouse is unstable and works only half the time. Inout Director is easy to install and works like a charm.
It is much more functional and comfortable than the "borderless mouse". For Windows systems only - it's the best.
Discontinued The project is no longer being developed, but the program can still be downloaded and is running.
