DockDoor is a macOS application switcher and window manager that functions as a dock enhancement tool. It provides a system-wide interface for navigating, previewing, and managing open application windows using keyboard and mouse inputs.
The utility adds live window previews to the system dock, allowing for application window peeking when hovering over dock icons. It also includes a feature to lock the system dock to a specific display in multi-monitor setups to prevent it from automatically jumping between screens.
The project covers a broad range of window management capabilities, including keyboard-driven window switching, gesture-based navigation, and programmatic window state control. It provides command-line utilities for querying window metadata and triggering visual previews through scripts.
