Last update from November 2021. Main developers moved to Input Leap. For now both Input Leap and Barrier are more or less at the same state, but going forward Input Leap might be the better choice.

Fantastically easy to use, although only on windows computers so it's not always an alternative to Synergy (which I'm using right now, because Linux...)

Buggy installation. "Link" button does not work half the time. Would not connect even with correct code and computer name, on the same network.

It's very reliable, and the double tap to switch screens is great. Clipboard sharing works well too. The little window to show status helps when you have multiple monitors.

While the description is a little vague, they seem to imply that your keyboard/mouse input is sent to another PC when you move your mouse into a tiny window on either PC.
