Free for 5 computers
Use a computer that isn't in front of you.
Your office PC. A server in a rack. A Raspberry Pi at home. Open it from wherever you are — even when it sits behind a router or a firewall you can't change.
Two pieces, on two computers
You install a small program called the agent on the computer you want to reach. You use the client on the computer in front of you. The two find each other and connect directly.
Agent
Goes on the computer you want to reach. Install it once and leave it.
Client
Goes on your own laptop — or just use the browser, with nothing to install.
The usual mix-up: putting them the wrong way round. Nothing connects, and it looks like the product is broken. The download page tells you which file is which.
Setting it up takes about a minute
-
Install the agent
One command, or one double-click, on the computer you want to reach.
-
Type in the code
Your client shows a short code. Enter it on the other computer.
-
Check the six digits match
Both screens show six digits. If they match, you're connected to the right computer. If they don't, stop — something is wrong.
What you can do once you're in
Run commands
A full command line, with full administrator rights.
See the desktop
The actual Windows desktop, or a terminal on Mac and Linux.
Move files
Copy things on and off the machine.
Reach things next to it
A database or admin page that only that machine can see becomes reachable from yours.
We can't see any of it
There is no RelayKey server in the middle. Your two computers talk straight to each other, and everything between them is scrambled with keys that only they hold. We don't run an account system, we don't store your files, and there is no company database with your machines in it.
That also means there is no password for us to reset. Your account is a key kept on your own computer. Lose it and it's gone — so keep a backup somewhere safe.
Read this before you install it
Anyone who pairs with the agent can do anything to that computer. Install programs, read every file, change the password, wipe the disk. There is no limited mode.
So: only install it on computers you're responsible for, and never share the pairing code. Anyone who gets that code before you finish pairing can take the machine instead of you. Type it in yourself; don't paste it into a chat.
Free for 5 computers
No trial, no card, not a limited version — five is genuinely free. Need more? It's $10 per computer per year, and cheaper above 20.
