DockDoor has been my passion project for the past year, and I'm thrilled to finally share it with the ProductHunt community! It's a powerful window management tool for Mac that gives you preview thumbnails when hovering over dock icons and advanced window switching controls (like Alt Tab on Windows). Unlike HyperDock, DockMate, and other alternatives, DockDoor is lightweight, fully native, FREE, private and designed for modern macOS. The response from early users has been incredible, and I'm especially proud that our amazing community has already translated it into multiple languages such as Chinese, French, Italian, Portuguese, etc. Whether you're organizing multiple windows or just want to quickly see what's running without switching apps, DockDoor makes your workflow smoother. I'd love to hear your feedback and suggestions as you try it out!

Big congrats on the launch! Dockdoor feels like one of those tools you didn't realize you needed until you see it in action. Super handy for streamlining logistics and inventory workflows. Wishing the team loads of traction and love on PH today!

Great, it can definitely improve productivity, I just don't quite understand the app's icon.

This is a gem. You should list it on Aixyz.Co—more people need to find it.

Congratulations, @keplercafe!

I tried it, but I had to see all the windows that should be invisible on windows switcher.

For example, I set my macro app invisible in the dock or Cmd+Tab, but the switcher still shows it.

And, is there any way to scroll vertically on switcher?

Thank you so much for your effort! I love it :)

Congrats on the launch of DockDoor — this looks fantastic! 👏

The hover preview + native performance combo is something Mac power users have been craving for years, and it’s impressive that you’ve built it to be lightweight, free, and privacy-first. That alone sets it apart from tools like HyperDock, which can feel clunky or abandoned.
