Overview

Barrier Free Download – Share Mouse and Keyboard Across Computers

Barrier is a free and open-source software KVM that lets you use one keyboard and mouse to control multiple computers over a local network. It is a fork of the popular Synergy 1.9 codebase and works across Windows, macOS, and Linux. This article provides a comprehensive guide to downloading, installing, and using Barrier.

What is Barrier?

Barrier is an open-source KVM (Keyboard, Video, Mouse) software developed by the Debauchee Open Source Group. It is available for Windows, macOS, and Linux, and is distributed under the GPLv2 license. The latest version is 2.4.0.

Barrier mimics the functionality of a hardware KVM switch, which historically allowed users to control multiple computers with a single keyboard and mouse by physically turning a dial. Barrier does this in software, allowing you to move your mouse cursor seamlessly between computers on the same network and share clipboard content between them.
