No cloud sync, no subscription required, no Dropbox or Google Drive dependency. Everything runs on your machine; Pro is $39 once.
Mixo's pitch is a cloud-first, multi-device DJ library: your crates and cues sync through Dropbox or Google Drive, and everything stays in step across Mac, Windows, iOS, and Android. For DJs who actually use multiple machines that's useful — but it also means you're paying monthly, tying your library integrity to a cloud account, and handing library metadata to a third party. If you use one machine, don't want a subscription, and don't want anything in the cloud, the cost-benefit flips.
Supported today
Rekordbox · Serato DJ · VirtualDJ (incl. Favorite Folders) on Windows 10+ and macOS (Apple Silicon + Intel). No DJ software? Folder Library mode audits plain music folders too.
Mixo: the desktop app is free; MIXO:GOLD is $7 a month and includes cloud sync, export to DJ apps, USB, the mobile app, playlist matching (Spotify, Tidal, Apple Music, and since version 2.14 YouTube Music, Beatport and others) and a duplicate finder.
Music Library Doctor: the free tier shows the Library Health Score and every missing track, duplicate and broken path. Pro is $39 once, or $9.99 a month: bulk repair of missing tracks, duplicate cleanup by sound, fake-320 and fake-FLAC detection, playlist conversion and Track Matcher. Fully local, no cloud account.
The short version: if you need your library on several devices or on your phone, Mixo is built for that. If you want your existing library repaired on one machine and to own the tool outright, MLD fits better.

MLD is the opposite philosophy to cloud-first library management. There is no online component — no login, no sync, no uploads, no third-party storage dependency. Your library metadata never leaves the machine, the local database is SQLCipher-encrypted, and writes go straight into each DJ app's native format. The tradeoff is obvious: MLD doesn't sync your library between devices. If multi-device cloud sync is your primary need, a cloud-first tool is the right shape; if you want full local control at a one-time lifetime price, MLD is designed for that slot.
No. MLD is a local tool — it never uploads library data. If multi-device sync is a hard requirement, a cloud-first tool is the right pick. Many DJs run on one primary machine and don't actually need sync — that's the case MLD is built for.
No. MLD has zero cloud dependencies. You install it, it reads your local libraries, you use it offline.
It's optional. Pro is $39 once and yours to keep, with updates included, or $9.99 a month if you only need it for a job. Nothing needs a subscription to work.
No. Every scan and every write is local. MLD's own database is encrypted with SQLCipher, and music files themselves never leave the machine.
Rekordbox (including encrypted 6+ master.db), Serato DJ Pro & Lite (native `%%` crate hierarchy), and VirtualDJ Home & Pro (portable and shared installs, Favorite Folders included).
MLD is desktop-only (macOS + Windows). There's no iOS or Android companion — library work happens where the DJ software runs.
Yes. The free tier shows the Library Health Score and flags every detected issue — missing tracks, duplicates, broken links, scatter. Bulk fix actions require Pro.
Free tier covers scanning and detection. Pro is a one-time lifetime license, or a monthly plan if you prefer. Current pricing is on the homepage.
It finds Rekordbox, Serato and VirtualDJ on its own, and reads plain music folders when you use none of them. Nothing to configure before the first scan.
macOS 10.15+ or Windows 10+. Notarized and code-signed. See pricing
