A free, open-source macOS menu bar app that scans every registered keyboard shortcut across your apps, Karabiner-Elements, skhd, and macOS system shortcuts, then shows exactly where they collide. No accounts, no telemetry, no dependencies.
Hi everyone. I make small Mac utilities, and several of them depend on global keyboard shortcuts. Every time I wanted to assign a new one, I had to guess whether it was already claimed by another app, a system shortcut, or an automation tool. There was no simple way to check, so I built HotkeyClash.
It scans every registered shortcut on your Mac in a single pass and shows you exactly where they conflict, with app icons and source badges. It also separates real conflicts (two global hotkeys on the same combo) from harmless overlaps (two apps reusing a shortcut in their own menus).
It is completely free and open source under GPL-2.0. No accounts, no telemetry, no network access, zero third-party dependencies. Signed and notarized by Apple. macOS 14 and up.
This is the first release, so I would love your feedback, bug reports, and feature requests. Next up: parsers for Keyboard Maestro, BetterTouchTool, Hammerspoon, Alfred, and Raycast, plus a live mode that shows which app actually catches a combo when you press it.
