A KVM switch
you install.

Press a hotkey — your monitor flips between any two computers. Keyboard, mouse, and audio follow. No hardware box, no port matching, no traffic ever leaves your LAN.

The hardware-KVM problem

Stop hunting for the right box.

You don't actually want a KVM. You want the result of a KVM — one monitor flipping between two computers, keyboard and mouse following along. EasyKVM gives you the result without the box.

Hardware KVM

Port matching is a nightmare.

You need DP-out → DP-in on the monitor side, USB-C maybe, the right HDMI revision, and a power-delivery rating that won't throttle your laptop. One wrong spec and you're returning a $200 box.

Hardware KVM

Cheap units drop USB devices on switch.

The $40 KVMs re-enumerate USB every flip. Your DAC pops, your gamepad disconnects, your Yubikey forgets it was inserted.

EasyKVM

One install. Done in 5 minutes.

Both apps pair with a 6-digit code over your LAN. Your monitor switches via DDC/CI — the same way the OSD buttons on the front do. Nothing physical changes on the USB side.

How it works

Three steps. Five minutes.

You'll have it running before the Amazon delivery window even opens.

MAC

Install on both machines.

Lightweight, signed installers for macOS and Windows. Drag, double-click, done.

2 7 1 8 4 4

Pair with a 6-digit code.

One machine generates a code, the other types it. TLS handshake + cert pinning — no accounts.

⌃ ⌥ Q

Pick a hotkey. Press it.

Monitor flips inputs, keyboard and mouse hand off to the other machine. Press again to come back.

What you get

The hardware-KVM feature set.
Without the hardware.

One hotkey, swaps everything

Monitor input via DDC/CI, plus keyboard, mouse, and audio handoff. All on one keypress.

Native display quality

We don't stream pixels. Each computer drives the monitor directly — no compression, no frame drops, no latency.

LAN-only by design

Pairing, keystrokes, audio — all of it stays on your network. No relay server to breach, no cloud session to hijack, no telemetry to leak. The license check is the only thing that ever touches the internet.

<50 ms keypress latency

Typical LAN round-trip is single-digit milliseconds. Mouse tracking feels native.

Mac and Windows, one license

A Windows PC acts as the host (it drives the monitor input over DDC/CI). Your Mac — or another PC on the same LAN — joins it. One license covers the host; joiners need no account.

Emergency kill hotkey

If you ever feel "stuck" capturing input, a second global hotkey instantly restores local control.

FAQ

Questions you'd ask before $29.99.

Does my monitor need anything special?

It needs DDC/CI — a small protocol the OS uses to talk to your monitor over the existing video cable. Almost every monitor made after ~2015 supports it. If yours has on-screen menu buttons on the front, it almost certainly works. We list known working models in the docs, and the 14-day trial will tell you for sure.

Does one side have to be a Windows PC?

Yes — for now, the host machine (the one running the license) needs to be a Windows PC, because Windows is where we drive DDC/CI to actually switch the monitor's input. Your Mac, or a second PC, joins over the LAN. PC ↔ PC works without caveats. Mac-as-host is on the roadmap once we work out DDC/CI on Apple Silicon.

Does it work over Wi-Fi?

Yes, as long as both machines are on the same LAN. Ethernet on at least one side gives you the snappiest mouse feel, but Wi-Fi 5 / 6 is fine for typing and everyday use.

What about audio?

Audio follows whichever computer is currently active. On Mac we use ScreenCaptureKit; on Windows, WASAPI. You can disable it in Settings if you'd rather keep audio local.

Free trial? Do I need to sign up?

3 days of full functionality, no credit card — long enough to confirm it works on your hardware. After that the host machine needs a license: you sign in once with the email you bought with, and that unlocks it. The other computer doesn't need a license or an account; it just joins on the LAN.

Does the other computer need a license too?

No. One license covers one host machine. Any computer on the same LAN can join it as a client — no extra license, no extra account. Move the license to a different host with the “Change host” action in your account (available once every 30 days).

Refund policy?

14 days, no questions — that's the EU consumer-law right of withdrawal, and we honor it everywhere. If your monitor doesn't expose DDC/CI or anything else surprises you, just reply to the receipt email.

More than two machines?

Strictly two machines per pair right now — one host (a Windows PC) and one joiner. Multi-joiner support is something we'll look at once the two-machine flow is rock solid.

Do you collect any data?

No usage analytics, no crash telemetry. The app talks to three things and nothing else: your peer machine over LAN, the GitHub releases server when it checks for an update, and our license server once per launch to verify your account. Your keystrokes, mouse movements, audio, and clipboard never leave your network.
