HotkeyClash
Scans your Mac's apps, Karabiner, and system shortcuts to find colliding hotkeys.
HotkeyClash scans every running app's menu shortcuts, your Karabiner/skhd config files, and macOS's own system shortcuts in one pass, then lists every key combination two or more of them claim. It flags a "definite conflict" when two global hotkeys collide, and a weaker "potential conflict" when a global hotkey only overlaps an app's menu shortcut. It's free, open source under GPL-2.0, and the only one of its rivals that checks all three sources at once.
What holds up
- +Free and open source under GPL-2.0, no subscription, and you can read every line
- +No telemetry, no cloud, no accounts, the scan runs entirely on your own Mac
- +Scans running apps, Karabiner/skhd configs, and macOS system shortcuts together, rivals check only one
Mind the limits
- −macOS 14+ only, no Windows version for users who split time between platforms
- −Finds conflicts but doesn't fix them, you still choose and remap the shortcut yourself
