A tiny pixel war party that camps and adventures along the edge of your Mac desktop, fighting to whatever music you play.

Free. macOS 15 or newer, Apple silicon. About 2 MB. Unsigned, so macOS warns you once.
Listens to whatever your Mac is playing (Spotify, YouTube, anything). No microphone, no extra drivers.
Kicks bring ground slams, snares bring sword strikes, and a big drop makes everyone unleash their best move at once.
Campfire: the party hangs around the fire and spars. Walk: they travel through forest, meadow, snow and aurora nights, speeding up with the tempo.
Everyone bobs in time, kicks thump the ground, and the fire and sky pulse with the music.
Lives in a corner or a strip along the bottom. Clicks pass straight through, it fades when you hover, and Option-drag moves it.
Agness the dog comes standard, with Pounce Bite, Zoomies and Bark Blast. Add your own pets too.
Pick a photo of your dog (or cat, or snake) and Riff Raiders asks Claude to draw it as a pixel sprite in about a minute. Name it, give it up to four moves (fire breath, tornado, chain lightning, blizzard and about twenty more), and it joins the party. Up to three companions at once.
Needs Claude Code signed in on your Mac. Your photo is shrunk, stripped of location data, sent only to Claude through your own Claude Code account, then deleted.

If macOS says "Riff Raiders is damaged" instead, open Terminal, run xattr -dr com.apple.quarantine "/Applications/Riff Raiders.app", then open it again.
