Crate Cleaner is a Serato library manager for Mac. It kills duplicates, relinks broken files and builds harmonic sets, so you spend the night reading the room, not fixing metadata.
Years of downloads. Three copies of every banger. Files that turn red mid-set. Crates nested four deep. Cleaning it by hand is a weekend you'll never get back, so it never gets done.
The same track in MP3, FLAC and a dirty edit, eating gigabytes and cluttering every search.
Moved drives and renamed folders leave broken links that fail the moment you load them on stage.
No BPM, no key, no waveform. You're guessing at transitions instead of mixing in key.
Hundreds of overlapping crates with no system. Finding the right record kills your momentum.
Three steps from a messy library to a gig-ready one.
Open Crate Cleaner and select your Serato database. Everything reads read-only, so your library is safe before you change a thing.
One scan returns a health score, a ranked fix list, duplicate groups and missing-file matches across your whole collection.
Dedupe, relink and build smart crates, then commit changes while Serato's closed. Archived files stay restorable forever.
A composite health score across four signals: missing files, corrupt files, duplicates and uncrated tracks. Top Fixes ranks every action by score impact, so you always know the next move that actually matters.

Exact, acoustic fingerprint, metadata, filename and fuzzy matching, grouped by confidence. Auto-pick keeps the highest bitrate, most cues, earliest added, and the file you keep inherits its crates. Nothing is deleted: it's archived, and restorable anytime.

Set rules for BPM, harmonic key, energy and genre. Crate Cleaner auto-builds the set along an energy arc to your peak, scores the harmonic flow, labels every transition, then exports straight back to Serato.

Browse any crate with analyzed BPM, Camelot key, cue counts and format inline. Search the entire library instantly, sort by energy, and preview without ever leaving the window.

Six more tools in the same app. Each one has its own page with the details.

Finds the start and the lifts in every track and writes them as real Serato hot cues. You review each one, and the whole batch undoes in one click.

Yes. Scans are strictly read-only, and Crate Cleaner only writes when Serato is closed, and the status bar tells you when it's safe. Removed duplicates are moved to a restorable archive, never hard-deleted, so you can always roll back.
Always. Beatgrids and cue points are preserved, and when you resolve a duplicate the track you keep inherits the crate memberships of the ones you remove, so nothing falls out of your sets.
MP3, FLAC, WAV, AIFF and AAC, the formats Serato DJ Pro reads. Crate Cleaner profiles your whole library by format and bitrate so you can prefer your highest-quality copies automatically.
