Unified
Combine your computers
Synergy makes all your computers feel like one system. One mouse, one keyboard, one clipboard. Just move your mouse from one computer to another and start typing.
Space
Increase desk space
Synergy means you only need one keyboard and mouse, regaining valuable space on your desk. Once installing Synergy, you can put away those extra keyboards and mice.
Accelerate
Save switch time
Conventional hardware switch devices cost precious seconds during the switch. Synergy has no delay, switching instantly as soon as you move your mouse between computers.
Input watch
Listens for inputs
Synergy listens to the operating system for mouse movements and key strokes, so it can tell when you move the mouse off the edge of your screen. Once it detects HID (human input device) events, it gets ready to send them over the network.
Emulation
Transmits HID info
Once off the edge, the mouse cursor is then emulated on the remote computer via your LAN (local area network). Keystrokes and copy/paste data are sent to whichever computer the mouse cursor goes.
Features
Security, copy/paste, and more
TLS/SSL encryption, copy and paste between computers, hotkeys, key swapping, and screen layout configuration.

Cherokee County 911
Synergy has been a valuable asset to Cherokee County 911, helping us to improve efficiency and effectiveness. The center is now able to handle a higher call volume with greater accuracy and speed without overwhelming dispatchers. This has made the community safer and has improved the quality of life for its residents.
Imperial College London
It was on everybody's mind to use Synergy's software to control every computer with one keyboard and mouse. Synergy is a robust and reliable solution that removes the difficulty of sharing a mouse and keyboard between multiple computers. When everything fails, Synergy is still the most reliable tool we have around.
Full Sail University
Synergy enabled our team of educators to use video conferencing tools to accommodate both on-campus and distance students simultaneously. The ability to quickly deploy Synergy through our management tools made it a clear choice.

Amazing product. I've used it for several years on my Linux/Windows machines, and would highly recommend it to anyone who needs to use multiple computers at once.
Alan
Senior Embedded Software Engineer
This is the best keyboard / mouse sharing software out there. I have used others and while all of them are less than perfect, I have to rate this one the best.
Scot
I have several development PC's running various OS's and am tired of using KVM's. Synergy is a fantastic solution. I had it working within minutes of purchasing. This is a great tool.
Ted
I have a basic license and run synergy server on my MacBook Pro. I run synergy client on an nvidia tx2 dev board and also on a laptop with mint on ubuntu. Synergy works great. Exactly what I want. The mouse and keyboard work fine, copy-n-paste works fine. It's great.
Peter Leiser
Great software, works a treat across my 6pc's. When I had a problem (it was a Windows error) the support team were very quick to reply to my email and the advice given was second to none. Highly recommended
