SSH tunnels you can actually see
HostDock manages SSH port forwarding as saved rules: local (-L), remote (-R) and dynamic (-D) tunnels that also work as an HTTP proxy. All rules for all servers are on one page, and each can start when HostDock launches.
What you can do
Local, remote and dynamic
Reach a database behind the server, publish a local dev server through it, or browse through it with a SOCKS5/HTTP proxy on a single port.
One page for every rule
See all tunnels across all servers with their state. Rules run independently of terminal tabs and can start automatically at launch.
Explained as you type
The form explains each mode, draws a live diagram of where traffic goes and shows the equivalent ssh command.
Safe by default
Ports bind to 127.0.0.1. Opening one to your local network is an explicit choice that comes with a warning.
At a glance
| Modes | Local (-L) · remote (-R) · dynamic (-D) with SOCKS5 and HTTP proxy on the same port |
|---|---|
| Dynamic DNS | Target names are resolved on the server side |
| Binding | 127.0.0.1 by default; LAN binding is opt-in |
| Startup | Optional auto-start when HostDock launches |
| Connection | Each server’s tunnels use their own SSH connection, separate from your terminal |
| Clear errors | Port in use, permission denied, AllowTcpForwarding disabled, target unreachable |
| Sync | Rules sync between your computers inside the end-to-end encrypted vault |
Frequently asked questions
What is the difference between local, remote and dynamic forwarding?
Local forwarding (-L) makes a service reachable from the server appear on a port on your Mac. Remote forwarding (-R) makes a port on your Mac reachable from the server. Dynamic forwarding (-D) turns a local port into a proxy that sends any connection through the server; in HostDock that port speaks both SOCKS5 and HTTP proxy.
Can a tunnel run without a terminal open?
Yes. Forwarding rules have their own connection and keep running when you close terminal tabs. You can also set them to start automatically when HostDock launches.
