Whack-a-mole for tmux. A desktop dashboard for monitoring and interacting with tmux sessions across multiple machines. Panes that need attention light up red — whack them with a quick response and move on.

• Displays a tiled grid of all your tmux windows and panes across local and remote hosts
• Highlights panes that need attention (configurable pattern matching on pane content)
• Quick-action buttons to send common responses (yes, y, enter) to waiting panes
• Click any pane to focus it and type directly into it
• Full tmux prefix key support (Ctrl+B then command key)
• SSH connections to remote machines using pure Rust (no system ssh binary required)
• Works on Linux, macOS, and Windows

cargo build --release

Create a config.yaml in the working directory:

hosts:
  - name: laptop
    local: true
  - name: server1
    ssh: [email protected]
    # port: 22
    # key: /path/to/private/key

poll_interval_secs: 2

attention_patterns:
  - "Do you want to"
  - "Allow"
  - "yes/no"
  - "Permission"
  - "Press enter"

quick_actions:
  - label: "yes"
    keys: "yes\n"
  - label: "y"
    keys: "y\n"
  - label: "enter"
    keys: "\n"

• local: true — monitors tmux on the local machine
• ssh: user@host — connects over SSH with key-based auth
• port — SSH port (default: 22)
• key — explicit path to SSH private key (default: tries ~/.ssh/id_ed25519, id_rsa, id_ecdsa)

Strings matched against the last 15 lines of each pane. When a match is found, the pane border turns red and quick-action buttons appear.

whackamux

Or with debug logging:

RUST_LOG=debug whackamux

• Click a pane to focus it for keyboard input (click again to unfocus)
• Type to send keystrokes to the focused pane
• Ctrl+B then a key to send tmux commands (c=new window, n=next, p=prev, etc.)
• X button on a window tile header to hide it from the grid
• Host tabs in the toolbar to filter by machine
• Quick-action buttons appear on panes that need attention
