Use another computer from wherever you are — its screen, its terminal, its files — even when it sits behind a home router or an office firewall.
Nothing you do passes through a server we can read. There is no account to sign up for and no password to choose.
1. Open app.relaykey.net and create an account. It takes a few seconds and works in any browser. Nothing to install on the computer you are sitting at.
2. Install RelayKey on the computer you want to reach.
On Windows, download relaykey-agent-gui-windows-amd64.exe from
Releases and run it.
On a Mac or Linux machine, paste this into its terminal:
curl -fsSL https://github.com/ptrinh/relaykey-public/releases/latest/download/install.sh | sh3. Pair the two. In the app, choose Add machine — it shows you a code. The machine asks for that code. Type it in.
4. Check the six digits match. Both screens then show six digits. If they are the same, you are talking to the right computer and nobody is in between. If they are not, stop — this is the one step nothing else can do for you.
That is the whole setup. From then on you get its terminal, its desktop, its files and a browser that runs on it, from the app or from any browser.
Everything is on the Releases page. If you followed the steps above you do not need this table.
| What you want | File |
|---|---|
| Windows — the computer you want to reach | relaykey-agent-gui-windows-amd64.exe |
| Windows — the app you control from | relaykey-client-gui-windows-amd64.exe |
| Mac — the app you control from | relaykey-client-gui-macos-arm64.zip |
| Mac or Linux — the computer you want to reach | install.sh (see above) |
| Servers, or no desktop at all | relaykey-agent-cli-… |
On an older Intel or ARM machine, pick the file ending in -amd64 or -arm64
to match it. Every release also ships SHA256SUMS, so you can confirm a
download is the file we published and not something swapped in on the way.
install.sh checks it for you and refuses to install anything that fails.
You do not need one. Add -per-user when you pair, and RelayKey installs for
your account alone:
relaykey install -per-user -paircode=CODEThe trade-off, stated plainly: on Windows and Mac the machine is then reachable only while you are signed in to it. On Linux it can usually keep running after you log out — the installer tells you which of the two you got rather than promising the better one.
The Mac app updates itself: Settings → About → Check for Updates.
