Barrier Alternatives and Similar Software

Synergy

Synergy combines your desktop devices together in to one cohesive experience. It's software for sharing your mouse and keyboard between multiple computers on your desk. It works on Windows, macOS and Linux.

• As Barrier is forked from earlier versions of Synergy, there is naturally a lot of feature set overlap. Whereas Barrier is focused on simplicity and ease of use, Synergy includes more robust features, including advanced settings for network, hotkeys, layout, security and diagnostics.

Mouse without Borders

Mouse Without Borders allows you to reach across your PC's as if they were part of one single desktop. Using Mouse Without Borders you can move your mouse between the 3 or more screens, even though one of them is attached to a different PC from the other two. You can also move files between the 2 computers simply by dragging them from one desktop to another.

• Viable as a Windows alternative to Barrier, though it is not supported on other platforms, nor is it open source. As it was developed by an employee of Microsoft and is available via the official Microsoft website, it may be easier to access in the face of Internet firewalls that block websites strictly. Additionally, it supports 32-bit versions of Windows, which Barrier does not. IanDorfman • Mar 2020 Disagree   Agree

If you have two or more computers on your desk and you are tired of having several keyboards and mice around to control them, this is the program for you. While running this program, you can move the mouse pointer beyond the right or left edge of your primary display and the pointer will appear on the other computer screen.
