Synergy 3 is here!
Introducing Synergy 3, the next big step for multi‑computer productivity.
We completely rebuilt our GUI from the ground up,
and implemented a brand new auto-config and
auto-discovery feature.
Control other computers on your local network with a single mouse and keyboard
Use the keyboard and mouse of one computer to control nearby computers. Copy and paste between all of your computers with shared clipboard.
Download for Windows, macOS, and Linux.
For tech enthusiasts
Used by millions of hobbyists, freelancers, and more
However you use multiple computers, Synergy lets you focus on doing what you do best.
Stay in your creative flow
Many artists use a Mac for creative work and a Windows PC for specific tools or older software. Synergy lets one keyboard and mouse control both computers as if they were one, so you stay focused on creating instead of switching devices.
For serious home labs
If you run several computers at once, Synergy lets one keyboard and mouse move between them instantly. No extra keyboards on the desk, no KVM switches, no remote desktop windows. Just slide across and keep working.
Coding across multiple systems
Tinkerers and freelance developers often juggle projects across Linux, Windows, and macOS. With Synergy, one keyboard and mouse control every machine, making it easy to test, learn, and ship without the hassle of switching setups. More coding, less clutter.
No more desk chaos
Running two PCs for gaming or streaming? Synergy lets one keyboard and mouse control both, so you can control your streaming PC and get back in seconds, without breaking gameplay or dealing with clunky KVM switches or desk clutter.
Breathe new life into old devices
Have an old laptop or desktop sitting unused? Synergy turns it into a second computer for chat, music, or research, controlled from your main keyboard and mouse. No new hardware. Just better use of the machines you already have.

See how Synergy is really used
Trusted by enterprise
26% of the Fortune 1000 use Synergy
Leading organizations—including Google, Amazon, Apple, Intel, Nvidia, Cisco, GE, and HP—use Synergy to simplify complex, cross-platform environments.
Unified control in mission-critical operations
In mission-critical operations, staff often work across multiple independent systems at the same time. Synergy lets a single keyboard and mouse move instantly between communication, monitoring, and control machines, reducing delays caused by switching consoles or interfaces. This keeps operators focused on decisions and execution rather than managing hardware, even under sustained pressure.

Seamless multi-system financial workflows
Traders and analysts often run multiple machines to keep markets, risk systems, and compliance platforms separate. Switching between keyboards and consoles slows reaction time and clutters already busy desks. Synergy brings everything under one set of controls, helping teams move faster, stay focused, and execute with confidence when every second counts.
Contact our business teamStreamlined network and server operations
In control centers, operators monitor dozens of systems across mixed environments. Traditional setups force constant switching between consoles, slowing response times and adding clutter. Synergy unifies input across machines, giving staff faster access, cleaner workspaces, and greater efficiency when uptime and rapid action matter most.
Contact our business teamCross-platform developer productivity
Engineering teams often work across multiple operating systems to build, test, and ship software. Managing separate keyboards, mice, or hardware KVMs adds friction to everyday workflows. Synergy lets developers move instantly between environments using a single keyboard and mouse, keeping focus on the work rather than the setup.
Contact our business teamOptimised driver and hardware validation
Driver and hardware engineers routinely work across multiple machines and operating systems. Managing separate keyboards, mice, or switches adds friction and clutter to test benches and labs. Synergy lets teams control all systems from a single keyboard and mouse, making it easier to move between environments while keeping labs simple and orderly.

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.

Great software is only half the story — it matters even more that help is there when you need it. Whether you’re a business or a personal customer, our support team is quick, clear, and genuinely helpful.
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.

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
