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 — 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.

Top spacedesk Alternatives & Similar Software (2020)
Synergy is yet another software that lets you work on separate computers with the same input devices. It helps you save all the clutter caused by the cables of a traditional KVM. What’s more, it works even when the computers are working on separate operating systems. This feature makes it stand out from Spacedesk. For Synergy to function, you’ll need the systems to run on...

  • Hrvach/Deskhop: Fast Desktop Switching Device
    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. Sometimes if the host machine bogs a bit (like running a build or something) then the clients will have some latency but I've used this setup for gaming and work for two years and it's been pretty good. My only complaint (about my personal setup, not the... - Source: Hacker News / 5 months ago
  • Hrvach/Deskhop: Fast Desktop Switching Device
    I’ve been using a software solution for this for over a decade. It’s called Synergy (https://symless.com/synergy) and it is fast - switches instantly over wifi and also works across Windows/Mac/Linux. - Source: Hacker News / 5 months ago
  • Hrvach/Deskhop: Fast Desktop Switching Device
    Synergy works well for this purely in software. Unfortunately it's not free or open source, but it's relatively inexpensive. https://symless.com/synergy. - Source: Hacker News / 5 months ago
  • Help me create a seamless LAN with a WAP on the end of a switch
    I want to be able to do things like Synergy, Steam Link, Unified Remote, and Media Servers between any of these devices, with as little added latency as possible (especially important for steam link). Source: 6 months ago

  • OpenVPNnot working and i dont know what to do

  • SSH into a personal computer in Jio Network using public IP
    I have a personal computer in the Jio Network at my home and I want to access it using ssh from another network. But in order to port forward my router I am stuck since Jio uses CGNAT if I am not mistaken and there is no use if I portforward. What other solutions do I have? I tried using portmap.io but I couldnt configure ssh in it (I dont want to use openVPN) so what other options do I have? Source: over 1 year ago
  • port forwarding/tunneling
    I'm basically looking for a free version of https://portmap.io/ -- they will do this, but custom domains are $4/month. Source: over 1 year ago
  • port triggering to replace port forwarding
    I would recommend trying again with port forwarding, or some other solution like this: https://portmap.io/ which is a kind of reverse tunnel made for situations like yours. That site has a free tier which allows a single forward. Source: over 1 year ago
