Reliable and fast

When you press a key on your keyboard or move your mouse, those actions are transferred at high speed over your local network (either WiFi or ethernet) to the computer you currently want to use.

Private and secure

Synergy doesn’t connect to the Internet. Your keystrokes and clicks are sent directly between your computers, and that’s it. For the highest security needs, local TLS encryption is available in higher editions.

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.

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.

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.

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.

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
