Synergy - Share one mouse & keyboard across computers

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.

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.

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
