Opus
From idea to sync-ready, on your Mac.
Opus is a music library for producers who are building a real catalog, not just organizing playlists. Most music tools assume your tracks are already finished and just need uploading somewhere. Opus starts earlier — it tracks your ideas from idea → in progress → sync ready → pitched → licensed, so you always know what's actually ready to send out and what's still just a motif in a folder. What it does: - Links your existing audio files (masters, stems, alt mixes) to creative "Tracks," without moving or reorganizing anything on disk - Tracks versions (full/60s/30s cuts) as a family, not separate unrelated files - Logs pitches and outcomes per track, so you know who you've already sent something to - A simple rights/splits record — collaborators, PRO status, license terms — living next to the music itself - A dashboard that surfaces what needs attention: tracks that are sync-ready but never pitched, pitches that have gone quiet, ideas that have stalled - One-click export bundles (like a "Sync Pitch Package": full/60s/30s + a one-sheet, zipped and ready to send) Everything lives locally on your Mac, no subscription, no uploading your masters to someone else's server, no lock-in. It's free, and I built it because I needed it myself. Why I built this: I'm a producer building out a sync catalog so the goal is something like 60-80 finished, pitch-ready tracks. The problem was never writing the music. It was everything around it: which version of which idea was actually done, which files I'd already pitched somewhere, which folder had the stems. I kept starting things and never finishing them, because there was no system telling me what state anything was actually in. So I built one. Opus tracks each idea through its real lifecycle: from a rough motif to something I've pitched to a licensed placement, and links straight to the actual files on my machine, no uploading, no separate database to keep in sync. It's not trying to be a marketplace or find you placements. It's the boring infrastructure underneath that — the thing that tells you what's actually ready to send out, so you stop guessing. I made it for myself first. If it's useful to you too, that's a bonus.
