The tool is simple, looks around in default locations for your ssh_configs and parses them as detailed by https://man.openbsd.org/ssh_config.5

Loads the data into a terminal UI and provides keybinds to interact with the data.

Under the hood nothing changes, system-wide utilities ssh, sftp, mosh, sshpass are used if present.

We could say, it's just a wrapper around ssh_config w/ some convenience methods built-in and a list of free, disposable shell servers one can easily access for testing.

Written in Go w/ a touch of urfave/cli & bubbletea.
