Description
macOS looks clean until you have five Safari windows open and no clue which one actually has the tab you need. DockDoor fixes that in the simplest way possible. Hover over an app in the dock, and it shows you every open window right there. You just click the one you want. That’s it.
It also adds a proper Alt+Tab experience. Not the macOS version that switches apps, but actual window switching with previews, the way Windows users are used to. Once you try it, going back feels weird.
You can close, minimize, or switch windows directly from the preview. You can even stay on your keyboard the whole time if that’s your thing.
And then there’s the privacy side. Everything runs locally. No analytics or background syncing. It’s one of those tools that just does its job and stays quiet.
Use Cases
- Quickly find and switch between multiple windows of the same app
- Use proper Alt+Tab window switching instead of macOS app switching
- Manage windows (close, minimize, focus) without leaving your current app
- Preview open windows directly from the dock
- Control everything using keyboard shortcuts instead of the mouse

A Better Way to Manage Windows on macOS
DockDoor feels like something macOS should already have. The dock finally gives you context and switching between windows stops being annoying. It’s lightweight and just fixes a gap that’s been there for years.
If you keep a lot of windows open, you’ll probably notice the difference on day one. If you don’t, you might still end up using it once you get used to previews.
