DockMaster vs AltTab: Window Switching on Mac
Both DockMaster and AltTab improve how you switch between windows on macOS. They solve similar problems but take very different approaches. Here's how they compare.
What AltTab Does
AltTab is an open-source window switcher that replaces the default ⌘Tab behavior with a Windows-style switcher. It shows thumbnails of all open windows in a floating grid, and you cycle through them with keyboard shortcuts.
What DockMaster Does Differently
DockMaster doesn't replace ⌘Tab. Instead, it enhances the Dock itself. Hover over any Dock icon to see live previews of that app's windows. It also adds a clipboard manager and a file shelf — features AltTab doesn't include.
Key Differences
| Feature | DockMaster | AltTab |
|---|---|---|
| Window previews | From the Dock (hover) | Floating grid (keyboard) |
| Preview type | Live, real-time thumbnails | Snapshot thumbnails |
| Clipboard history | Yes, built-in | No |
| File Shelf | Yes | No |
| Price | Free + Pro £14.99 | Free (open source) |
| Built with | Swift (native) | Swift (native) |
| macOS requirement | macOS 14 Sonoma+ | macOS 10.12+ |
When to Choose AltTab
AltTab is a good choice if you want a free, open-source ⌘Tab replacement and don't need clipboard or file shelf features. It works on older macOS versions and has a strong community.
When to Choose DockMaster
DockMaster is a better fit if you want window previews integrated into the Dock, plus clipboard history and a file staging shelf in one tool. It reduces the number of separate utilities you need. The free version covers basic use; Pro unlocks everything at £14.99.
