Doca
Comparison · checked Nov 8, 2026
Doca vs Seelen UI
Seelen UI replaces much of the Windows shell (bar, Start, window management). Doca is just a dock, and a good one: easier to start with, with the Mac magnifier and ready-made environments.
Quick answer
Pick Seelen UI if you want window tiling and a fully custom desktop, and don't mind lots of setup. And you don't want to pay anything. Pick Doca if you want the Windows you know with a better dock, one that works well from the first launch and puts everything back when it closes.

Where Seelen UI is better
- Free and open source (AGPL-3.0).
- Does much more than a dock: bar, Start menu, its own Alt+Tab and a tiling window manager.
- Frequent releases (2.8.10 on Oct 22, 2026) and a widget SDK.
Seelen UI's limitations
- It's a broad, more complex package if you only want a dock.
- The Store and winget versions may arrive days after GitHub.
- Mac-style icon magnification isn't mentioned in the official sources.
Where Doca is better
- Environments: one dock for each moment, with its own apps, widgets, color and windows.
- 40+ live widgets inside the dock, and you can build your own with a script.
- The Mac magnifier, with adjustable strength and width.
- It can replace the taskbar and restores everything on exit, even after a crash.
- Made by one developer who answers support email himself.
Doca's limitations
- It's paid: US$ 9 once, after 7 free days.
- It isn't open source.
- It groups windows by app, like the Mac (no named button per window).
- It isn't a tiling window manager.
- Requires Windows 10 2004 or newer.
