BetterTouchTool alternatives

Hammerspoon exposes macOS system APIs to a Lua scripting engine. One init.lua can bind hotkeys, tile windows into layouts, react to Wi-Fi or USB changes, control other apps' menus and add menu bar items. It is the closest free equivalent to BetterTouchTool's breadth. It is for developers and anyone happy to write a little code. There is no preferences UI; configs are text, so they are portable and easy to share. Free and MIT...

Karabiner-Elements is the low-level keyboard customiser for macOS. It runs as a virtual keyboard driver, so remaps apply everywhere: Caps Lock as a Hyper key, tap-versus-hold behaviour, layers, or a separate profile for an external keyboard.

Where BetterTouchTool is about what triggers an action, Keyboard Maestro is about what happens next: multi-step macros with variables, loops, conditions, image recognition and hundreds of actions, built visually without code. It is for people who outgrew BTT's action list. Triggers include hot keys, typed strings, USB device keys, MIDI, time and app events, plus clipboard...

Actions can be remapped to shortcuts, media keys, or per-app controls, with adjustable sensitivity. It is for MacBook and Magic Trackpad users who want tactile adjustments without reaching for function keys. Needs Accessibility...

Swipe a title bar to snap a window to a half or quarter, pinch to fullscreen, two-finger swipe to switch spaces. Around 30 gestures, all discoverable. It is for people who bought BTT to move windows and never touched the rest. No scripting, no keyboard automation, no Stream Deck, so setup takes minutes instead of an...
