Synergy - Share one mouse & keyboard across computers (original) (raw)
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.
Cross-Platform Developer Productivity
Your engineering teams are already context-switching between operating systems to build, test, and ship software. But every extra keyboard, mouse, or hardware KVM adds friction and slows delivery. Synergy eliminates that barrier, letting developers move seamlessly between environments on a single desk. Faster iteration, less distraction, and more focus on what matters — delivering quality software at speed.
Optimised Driver & Hardware Validation
Driver and hardware engineers often work across multiple machines and operating systems. Extra peripherals and constant switching slow progress and clutter labs. With Synergy, teams control everything from one workstation — cutting friction, speeding up debugging, and keeping labs streamlined.
Streamlined Network & 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.
Seamless Trading Desk 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.
Efficient Control & Command Operations
In dispatch and command centers, every second matters — and sometimes lives are at stake. Operators must move seamlessly between communication systems, mapping, and monitoring tools under intense pressure. Synergy removes the friction of juggling multiple consoles, letting staff stay focused and act without delay. The result is faster response, clearer coordination, and greater confidence when decisions carry the highest stakes.

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.
Breathe New Life Into Old Devices
Got an old laptop or desktop gathering dust? With Synergy, it becomes a useful extra screen for chat, music, or research — all controlled from your main keyboard and mouse. No need for new hardware, just smarter use of what you already own.
Hobby & Freelance Coding Made Simple
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
Two PCs? No problem. Synergy keeps your setup clean so you can crush your enemies and keep the stream running without missing a beat.
Tinker With Your Home Lab
Running a few servers, Pis, or test rigs at home? With Synergy, you don’t need a keyboard and mouse for each box. One setup controls them all, so you can focus on experimenting, learning, and building without the desk clutter.
Stay In Your Creative Flow
Artists and musicians often use different machines for their tools — macOS for creative apps, Windows for plugins or DAWs. With Synergy, one keyboard and mouse control both, so you can stay in the flow and focus on your craft instead of fighting your setup.
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.

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
