EasySwitch
macOS · Windows · Linux · your network only
EasySwitch links the computers on your desk into one workspace. Control them with one keyboard and mouse, move your clipboard and files between them, and turn another computer into a real second display.
Free forever for 2 computers · Pro $49 once · No subscription
One cursor, one clipboard, three machines — and the third one is a display now. No cloud, no internet needed — and never a mirror of your desktop.
Real footage
A MacBook and a Windows PC on one desk: pair once, move files both ways, type across, then give each machine the other's screen. Filmed, not rendered.
Four screens you'll actually use, captured on Linux. The same app runs on macOS and Windows.
Two Macs, a Windows PC and three Linux machines — each with its OS, its status and the screen edge it sits on.
New in 0.1.0 (b118) · Extend Pro
Pick a linked computer, choose Extend, and your machine gains a real second display — one your operating system treats like any other monitor.
Drag a window onto it. Work there. Take it back whenever you want.

Extend is part of Pro — a one-time purchase that also covers the keyboard, clipboard and files.
Not screen sharing
Every other way of putting one computer's picture on another starts by reading the screen you already have. Extend starts by making a screen you didn't.
The usual way
Whatever is on your screen leaves the machine.
EasySwitch
Your screen is never captured.
One desk
It just doesn't act like one computer.
Keep the one you like. Your cursor slides off the edge of its screen onto the next machine and the keyboard goes with it — the same way it already moves between two monitors.
Copy here, paste there. Or drag the file across the screen edge and drop it straight into Finder or Explorer. It works between a Mac and a PC, where AirDrop won't.
Point EasySwitch at it, press Extend, and the machine you're working on gains a screen. Put the things you keep glancing at over there and take the space back on your main display.
Slide the cursor off the edge of one screen and onto the next computer. The keyboard follows it.
Copy on one machine. Paste on another. Text, images and files.
Drag a file off one screen and drop it into Finder or Explorer on the other.
Turn a linked computer into a real extra display for the one you're working on.
Laptop, desktop, test box: crossings hand off machine to machine like one long desk, and the clipboard works between any pair of them.
Ctrl+Alt+2
Jump straight to a machine instead of dragging the cursor across three screens — the number is its position in your layout. Double-tap Ctrl to snap control back to the computer you're sitting at, even if the network stalls.
Ctrl+Alt+L
Pin the keyboard and mouse to the machine you're on so a stray cursor can't wander mid-sentence. Same chord to release it.
Ctrl+Alt+M
Turn the machine you're pointing at into an extra monitor, and turn it back into a computer when you're done. Part of Pro.
Sleep, a dropped Wi-Fi connection, a reboot — the machines find each other again and carry on, including a display you were extending onto.
Scan a QR code and send text or files from any phone or browser on your network. Nothing to install on the phone. Part of Pro.
How it works
A small native app on each machine — quick to start, light on memory, input latency in the low milliseconds on a LAN.
01
They find each other on your local network automatically — no IP addresses, no config files, no relay account.
02
Confirm the same fingerprint on both machines, then arrange them in Settings the way they sit on your desk — like a multi-monitor layout.
03
That's it. When you want a display instead of a cursor, pick the machine and hit Extend.

Runs on Windows, macOS and Linux, in any combination — Mac to Windows, two PCs, three of anything. One limitation is worth knowing up front and it's on the download page: what runs where.
Private by design
EasySwitch is not remote desktop and never mirrors a desktop. Extend doesn't capture the screen you're using — it creates a brand-new, empty display and streams only that, only while you have it switched on, encrypted, over your own network. Leave Extend off and nothing but input, clipboard and your files ever moves.
Everything is end-to-end encrypted between your machines, on every tier — encryption is never a paid feature. Licenses verify on your machine: the app talks to our server exactly once, when you add a key, and works forever after that with the internet unplugged. No account in the app, no telemetry, no cloud in the path.
What crosses the wire
How it compares
Some tools move your keyboard. Others move your screen. EasySwitch brings both together.
Competitor features as published 2026-08-04 — verify current terms on their official sites. Deskflow is excellent open source and spacedesk is genuinely free on Windows; if either covers your desk, use it happily. Full matrices, every dimension, and the head-to-head pages for moving off a tool you already use: KVM software · second-screen software.

Yes — mouse, keyboard and clipboard (text, images and files up to 10 MB) across two computers are free forever, including drag-and-drop. Pro lifts the transfer limit to any size, links 5 computers and adds the web bridge and virtual displays — a one-time purchase, never a subscription.

Both. Any combination works — Mac to Windows, two Windows PCs, two Macs, Linux to anything — with automatic Cmd ⇄ Ctrl shortcut translation, so copy/paste muscle memory works on every machine. There's no cross-platform requirement.
Second monitors, big-file transfers, hardware KVMs, working offline — the rest is in the full FAQ and the documentation.
Free forever for 2 machines — mouse, keyboard, clipboard, files and full encryption. No account, no card, no subscription.
