Your Mac reacts for real
Slappy reads your MacBook's motion sensor, then turns a tap into sound, volume, shake, flash, and haptics.

and it mouns
A tiny menu bar app that turns taps, lid movement, USB plugs, shortcuts, and Codex events into ridiculous Mac reactions.

More than a scream button
Slappy makes the whole Mac feel reactive: taps, hard slaps, lid movement, USB devices, app actions, and your coding agent can all trigger something.
Make hard slaps useful
Map light, medium, and hard slaps to do nothing, open an app, open a website, hide every app, or quit apps deliberately.
USB plugs talk too
Turn USB connect and disconnect moments into reactions, using the same selected voice pack.
Open the lid, hear it creak
On supported MacBooks, lid-angle movement becomes another trigger with gentle, medium, and dramatic sensitivity.
Pick the personality
Use built-in packs like Pain, Halo, Lizard, Combo Hit, Gentleman, Yamete, Goat, and your own imported sounds.
Make Codex audible
Install passive hooks so Slappy reacts when Codex starts, asks, uses tools, succeeds, fails, or gets blocked.
Hundreads of voices to choose from 11 sound packs
Preview the launch packs here. Inside Slappy, built-in packs and imported audio can become the voice for slaps, lid movement, USB events, and Codex hooks.
Use the chaos on purpose
The joke gets people in. The controls keep it useful enough to leave running in the menu bar.
Panic mode
One slap, clean desktop
Use the safe default to hide visible apps without quitting them, or opt into stronger actions when you really mean it.
Impact effects
Make impact feel physical
Tune screen flash, screen shake, brightness flash, haptic buzz, sensitivity, cooldown, and dynamic volume.

Slappy reacts in software to motion data. Use taps and gentle slaps, not real abuse. The joke is funnier when the laptop survives it.
