Barrier is a free, open-source application that lets you use a single keyboard and mouse to control multiple computers. It functions as a software KVM switch, eliminating the need for extra hardware. Set up a main server with your input devices, then connect client PCs over your local network. The mouse cursor moves seamlessly between screens of different systems, and the clipboard syncs across them. This solution is perfect for users working with several machines at once—such as developers, testers, or home automation enthusiasts. The program ensures secure connections and can be configured for various network setups.
