RelayKey

Download

You need two: the client for the computer you are at, and the agent for each computer you want to reach.

Windows

For the computer you are at

Windows client

Run it. Nothing to sign up for.

Download client
  • ARM version
  • Or use your browser — nothing to install.
  • Windows will warn you: click More info → Run anyway. We have not bought a signing certificate yet.

For the computer you want to reach

Windows agent

Double-click, then press Install.

Download agent

macOS

For the computer you are at

Mac client

Open it and drag RelayKey to Applications.

Download client
  • Apple Silicon only (M1 and later). On an Intel Mac, use your browser instead.
  • Homebrew: brew install --cask ptrinh/relaykey/relaykey-client

For the computer you want to reach

Mac agent

One command installs it, on Intel and Apple Silicon. Your client gives you a code to pair it with.

curl -fsSL https://relaykey.net/install.sh | sudo sh
  • Pairing registers the service, so this needs sudo.
  • Prefer a file? Download the binary — or the Intel build.
  • Homebrew: brew install ptrinh/relaykey/relaykey-agent

Linux

For the computer you are at

Use your browser

There is no Linux app. The browser does everything except forward a port.

Open app.relaykey.net
  • Chrome, Edge or Firefox. Works on a phone or tablet too.

For the computer you want to reach

Linux agent

One command installs it. Your client gives you a code to pair it with.

curl -fsSL https://relaykey.net/install.sh | sudo sh
  • Pairing registers the service, so this needs sudo.
  • Prefer a file? Download the binary — or the ARM build for a Raspberry Pi or Graviton.
  • Homebrew: brew install ptrinh/relaykey/relaykey-agent

Other

For the computer you are at

Use your browser

Nothing to install. It works on a phone, a tablet or a Chromebook — anything with a current browser.

Open app.relaykey.net
  • iOS and Android apps are coming soon.

For the computer you want to reach

Nothing to download yet

Android is coming soon. There is no agent for phones, tablets or Chromebooks today, so one of these cannot yet be a machine you reach.

  • To reach a Windows, Mac or Linux machine, pick it above.

Then pair them

  1. In the client, press Add machine to get a code.

  2. Enter that code on the other computer.

  3. Check the six digits match on both screens, then accept.

Whoever pairs with the agent can do anything to that computer, so only install it on computers you look after, and never share the code. More on this.
