About The Project
DockDoor reintroduces the missing "Window Peeking" functionality to macOS, inspired by the utility found in Windows and Linux environments.
While the native macOS Dock is iconic, it often lacks context when multiple windows of the same application are open. DockDoor solves this by allowing you to visualize, manage, and switch between your open windows simply by hovering over your Dock icons.
Built entirely open-source, DockDoor is designed to feel like a native extension of the operating system. Fast, lightweight, and seamlessly integrated!

- Live window previews with 20+ actions, plus a full Alt+Tab replacement
- Spring magnification at your display's full refresh rate
- Folder fan-out, a drag-and-drop file tray with AirDrop, and right-click quick actions
- Liquid Glass, frosted or clear materials, profiles, and a different dock on every display
- Widget marketplace with clock, weather, battery, now playing, and community widgets
$20 one-time for 3 Macs. No subscription, 14-day money-back guarantee.
