Dock Door Alternative

If you're looking for a Dock Door alternative, here's an honest take: you might not need one.

DockDoor is a free, open-source app that adds window previews and quick window switching to the macOS Dock. It's good at that, and it runs happily alongside ExtraDock.

ExtraDock gives you more than the default macOS Dock. Whether you want a dock on every screen, or to completely replace the Dock but keep window previews, ExtraDock covers both.

Friends, not foes

DockDoor

Window Previews on the Dock

DockDoor is free and open source. Hover an app icon on the macOS Dock and it shows previews of that app's open windows, so you can jump straight to the one you want instead of cycling through them.

Click a preview to switch to that window. You can also close or minimize a window straight from the preview, without bringing the app forward first.

It brings the kind of window switching Windows users miss on a Mac, and it stays out of the way the rest of the time.

Because it enhances the default Dock instead of replacing it, DockDoor pairs with apps that do the same, like ExtraDock or DockFlow.

One problem

There's still only one Dock

DockDoor makes the macOS Dock better, but it's still one Dock on one screen.

That's the gap ExtraDock was built to close: a dock on every screen, with any app, folder, or widget.

You don't need to fully replace the macOS Dock if you like it. ExtraDock works alongside it perfectly.

Native

Docks That Feel Like Home

ExtraDock stays with the Mac aesthetic: floating docks with rounded corners, translucency, and icons that look at home next to the native Dock.

ExtraDock gives you the same window previews DockDoor brings to the default Dock, now on every dock you create.

Workflow

Added Quality of Life

ExtraDock is not just for looks, it's built for daily use.

Drag and drop files directly into folders on your docks.

Collapse a dock when you want the space, hover to bring it back.

Appearance

Custom App Icons

macOS offers no way to change app icons in the Dock.

Workarounds edit the app itself but revert back with new updates.

ExtraDock sets custom icons per app, per dock, without touching the apps. Use any image and build the look you want.

Frequently Asked Questions

Everything you need to know about ExtraDock.

ExtraDock gives you multiple lightweight docks that you can pin anywhere across your screens. Use it as an add-on to your native Dock, or go all-in and replace it entirely — it's up to you.

Yes. ExtraDock works independently of the native Dock, so you can use both side by side or hide the native Dock and let ExtraDock take over. It's designed to fit however you work.

ExtraDock supports macOS 12 and later, including macOS 26 Tahoe.

Yes. ExtraDock has a setting that ensures resized and maximized windows respect your docks and won't cover them.

Yes. You can choose from a variety of both visual and behavioral customizations — colors, effects, opacity, borders, custom app icons, as well as auto hide/show, hide on full screen, and more.

Partially. macOS does not provide a way to read badges for Apple apps such as Mail and Messages, so those cannot be shown. Third-party apps like Slack and WhatsApp work as expected.

Yes, with limitations. ExtraDock docks can be attached to a specific screen, so they appear when that screen connects and hide when it disconnects. This relies on macOS identifying each display consistently. DisplayLink monitors and displays connected through docking stations or daisy chains can behave inconsistently, especially after sleep or replugging, which can affect screen recognition.

Live Dock mirrors your native macOS Dock on any screen, either your full Dock or just running apps. Dock Awareness shows only the apps running in your current Space and updates as you switch. Both update dynamically.
