Jump Hippo

Jump Hippo turns an SSH tunnel into something you stop thinking about. Bind a local port; the tunnel is not opened until something actually connects to it, and it closes again once traffic stops. The local listener stays bound the whole time, so the next connection simply re-opens it. It lives in the system tray, reaches destinations several hops away through jump-host chains, holds credentials encrypted at rest, and never phones home.

On-demand SSH tunnels

Bind a local port and the SSH tunnel opens the moment something touches it — through a chain of jump hosts if you need one — then tears itself down once the port goes idle.

Tunnels that open themselves

Connect lazily on first access and idle out on a timer you set. The listener never goes away, so nothing in your workflow has to know a tunnel was ever closed.

Jump-host chains

Reach a destination several SSH hops away by describing the chain once. Each hop is authenticated on its own terms.

Flexible authentication

SSH agent, private keys with passphrases, or passwords — stored encrypted at rest, never in a plaintext config file beside the app.

Host-key verification

Trust on first use with an explicit prompt, and a changed host key is refused rather than shrugged at. The check that protects the tunnel is not optional.

Live monitoring

Per-tunnel state, byte rates and connection counts, in a card view or a sortable list — so a tunnel that is quietly failing looks different from one that is quietly idle.

Nothing leaves the machine

No telemetry, no account, no update beacon. The only network traffic Jump Hippo makes is the SSH you asked it for.
