Barrier

Barrier is a utility designed to share a single mouse and keyboard across multiple computers connected to the same local network. It functions by designating one machine as the server, which captures input events, and others as clients that receive these events over a network connection. The software operates by creating a virtual input device on the client machines, allowing the cursor to move across screen boundaries as if the displays were part of a single desktop environment.

Configuration requires defining the relative physical layout of the monitors within the application interface. It supports clipboard synchronization between connected systems, enabling text to be copied on one machine and pasted on another. The software is primarily intended for users managing multiple workstations simultaneously and relies on a stable network connection to maintain input responsiveness.
