Link Host for Linux, macOS and Windows
Your computer,
in your pocket.
Link Host gives the Link app one encrypted connection to your computer: its coding agents, terminals, files and screen. No port forwarding. No VPN to set up.

link-host ssh setupLeave your desk
Your phone reaches the computer from any network. Nothing to forward or open.
link-host devicesNo network settings
Your computer only makes outgoing connections. It never waits for the internet to call in.
Read how the phone finds it- Direct
- Same network, or an address the phone can reach: straight to the computer.
- Punched
- Different networks: both sides meet and open a direct path between them.
- Relayed
- When no direct path opens, through a relay you deploy, which only sees ciphertext.
