Barrier is a cross-platform software utility for sharing your mouse and keyboard between multiple computers on your desk. It was forked from Synergy version 1.9's codebase.
As a keyboard, video, and mouse utility, Barrier aims to maintain the simplicity found in Synergy versions released before 2.0. Barrier's goals are the following:
• Let you use your keyboard and mouse from machine A to control machine B (or more)
• Hassle-free reliability
• Compatibility, with the aim being to "just work" with Windows, macOS, Linux, FreeBSD, and OpenBSD
• Development communication by utilizing the open source development and release model
While focused on simplicity and ease of use, Barrier does support both clipboard sharing and SSL encryption.
Barrier currently does not support drag-and-drop on Linux kernel-powered operating systems, and it will not run at all on 32-bit versions of Windows. Windows 7 or later is required.
