Your library. Your machine. Your call.

Metamix exists because DJ libraries have outgrown DJ software. Archives of 10,000–20,000 tracks hold decades of taste — but the tools treat them like folders, and preparing them means hours of manual analysis, tagging, and cue placement.

Metamix is a local-first workstation that bridges your archive and your performance library: it browses like a streaming service, analyzes on Apple Silicon, tags with explainable local models, and writes cue points into Rekordbox — carefully, with snapshots and undo, and never over the edits you made by hand.

The principles are simple. Your music never leaves your Mac. There's no account, no cloud, and no subscription. The Rekordbox grid is the authority, your manual edits are sacred, and every automated change is planned, diffed, audited, and reversible.

Metamix is built by Quantum Development, a small independent software lab. Development happens in the open — follow the build log for an honest look at how it's made.
