Barrier for Windows

Unified input control for multiple computers

Barrier is an open-source KVM tool that lets one keyboard and mouse control several machines across a local network. It removes the need for physical switches or extra peripherals, so you can move between systems smoothly and keep your workspace tidy. Barrier’s straightforward interface makes connecting and switching between computers quick, helping you maintain focus and speed up common tasks.

Installation, setup and compatibility

Getting Barrier running is simple: install the application on each device you want to control, choose one as the server, and link the others as clients. The configuration workflow is intentionally minimal, with visual tools to map screens and arrange machines. Barrier runs under the GPLv2 license, so it’s free to use and distribute. It supports multiple operating systems, making it suitable for environments that mix Windows, macOS and Linux systems.

• Runs on Windows, macOS and Linux for mixed-platform environments
• Uses a GUI-based configuration to speed up setup
• Operates over the network, eliminating extra hardware
• Distributed under GPLv2 so the software is free to use

Practical advantages for daily use

Using Barrier declutters your desk and reduces interruptions caused by switching between separate keyboards and mice. It’s particularly useful for developers, power users, and anyone who manages more than one computer at a time. Once configured, switching control is as simple as moving the cursor to the edge of a screen, and clipboard sharing between machines streamlines copy/paste workflows.

• Clipboard sharing between linked systems
• Cursor movement that seamlessly crosses displays
• Reduces the amount of desktop hardware required
• Ideal for multitasking across multiple machines

Alternative to consider

If you want a different free option for cross-device interaction (primarily for file and media transfers rather than KVM control), you might look at SHAREit (free). It offers fast file sharing across devices but serves a different niche than Barrier.
