SSH Tunnel Manager for macOS

SSH Tunnel Manager is a free, open source menu bar app for macOS that manages SSH port forwarding. You set up your tunnels once, toggle them on or off from the menu bar, and the app reconnects them automatically when the connection drops.

It is a native Swift app that wraps the system ssh client, so it reuses your existing ~/.ssh/config and keys. No bundled binaries, no Electron. It supports local forwards (-L), remote forwards (-R), dynamic SOCKS proxies (-D), and jump hosts (-J), with multiple port mappings per connection.

Other features:

• Auto-reconnect when a tunnel drops
• Readable failure reasons (auth, connection refused, host unreachable, DNS, host-key change, port already in use), not just "disconnected"
• Port-conflict guard so two tunnels do not fight over the same local port
• Tunnel grouping with a single toggle per group
• Optional sound and notification alerts when a tunnel connects or drops
• Per-tunnel SSH options (connect timeout, keepalive, compression) plus a free-text field for any extra flags
• Launch at login and auto-connect on startup
