Every "slap your MacBook" app in one honest table. The short version: most cost money and make you fight Gatekeeper. Here's how they stack up.

The whole app is free forever with every effect included: feather-touch slap detection, fake screen damage, lid drama and port sounds. It's built to be signed and notarized, so it opens with a double-click instead of a terminal command. Pro ($9.99, one-time) only unlocks importing your own sounds. If you want the most app for the least friction, start here. Download it free.
The app that started the trend. Polished and fun, but it's a $9.99 paid app with no free tier, and like the others it ships unsigned, so you'll hit a Gatekeeper warning on first open. Best if you specifically want the original.
A feature-rich clone at $2.99 with fake damage, lid sounds and port reactions. Good value, but there's no permanent free version and it still needs the manual "remove the quarantine flag" step to open.
A free, open-source reimplementation on GitHub. Genuinely free, but you download a raw binary that macOS blocks until you run a command, and it has fewer of the extra reactions.
The one thing that separates them: nearly every slap app hands you an unsigned file and a terminal command. Slap Your Mac is the one designed to open cleanly, which is exactly what you want from a novelty app you're installing for fun. If price is your only filter, here are the best free slap Mac apps.
