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

Unzip it and drag it 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 sets it up. Works on Intel too.

Download agent
  • Intel version
  • Or: curl -fsSL https://github.com/ptrinh/relaykey-public/releases/latest/download/install.sh | sh
  • 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 sets it up as a service.

Download agent
  • ARM version — Raspberry Pi, Graviton
  • Or: curl -fsSL https://github.com/ptrinh/relaykey-public/releases/latest/download/install.sh | sh
  • Homebrew: brew install ptrinh/relaykey/relaykey-agent

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.
