About:
Barrier is a cross-platform open-source KVM (Keyboard, Video, Mouse) switch software that lets you share a single mouse and keyboard between multiple computers. It works over a network connection, effectively turning multiple machines into a single unified desktop environment. This eliminates the need for physical hardware switches and boosts productivity for multi-system setups.
Key Features:
  • Network-based KVM switching without hardware
  • Clipboard sharing and file transfer between computers
  • Supports Windows, macOS, and Linux
  • Configurable hotkeys and screen mapping
Use Cases:
  • Developers managing multiple operating systems simultaneously
  • Users with dedicated work and personal computers on the same desk
  • QA testers working across different platform environments
Alternatives:
  • Synergy – Barrier is a free and open-source fork of the original Synergy software
  • ShareMouse – ShareMouse offers Windows-native features but is proprietary and paid
