Synergy is a software application developed by Symless. It is used for sharing a keyboard and mouse between multiple computers, and is useful in situations where several PCs are used together, with a monitor connected to each, but are to be controlled by one user. The user needs only one keyboard and mouse on the desk โ€” similar to a KVM switch without the video.

Partly open source and partly closed source, the open source components are released under the terms of the GNU General Public License, which is free software. The first version of Synergy was created on May 13, 2001, by Chris Schoeneman and worked with the X Window System only. Synergy now supports Windows, macOS, Linux, and other Unix-like operating systems.

Once the program is installed, users can move the mouse "off" the side of their desktop on one computer, and the mouse pointer will appear on the desktop of another computer. Key presses will be delivered to whichever computer the mouse-pointer is located in. This makes it possible to control several machines as easily as if they were a single multi-monitor computer. The clipboard and even screensavers can be synchronized.

The program is implemented as a server which defines which screen-edges lead to which machines, and one or more clients, which connect to the server to offer the use of their desktops. The keyboard and mouse are connected to the server machine.

I use Synergy as part of my desk setup already, but needed a way to view the UI of a normally headless machine.

    I use a software called Synergy. https://symless.com/synergy I have one keyboard and mouse connected to one "host" machine, and two machines connected as clients.
