Music Library Doctor
Alternative comparison

A local alternative to Mixo.dj

No cloud sync, no monthly subscription, no Dropbox or Google Drive dependency — everything runs on your machine, on a one-time license.

The problem

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.

How Music Library Doctor does it

  1. 1 Install Music Library Doctor on your Mac or Windows machine. It reads Rekordbox (encrypted 6+ master.db supported), Serato crates (with `%%` hierarchy), and VirtualDJ database.xml (portable installs detected, Favorite Folders supported).
  2. 2 The Library Health Score shows a single 0–100 number covering missing tracks, duplicates, broken links, and folder scatter.
  3. 3 Use the Group Scorer to dedupe — bitrate, file size, folder, filename quality, DJ-library usage all factor in. Playlists are re-pointed to the winner before any file moves to Trash.
  4. 4 Use the Folder Consolidation Wizard to bring a scattered library into one target folder — every DJ app's database is updated in the same pass.
  5. 5 Transfer playlists between Rekordbox, Serato, and VirtualDJ — native writes, no XML middleman.

Why native integration matters

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, Mixo is built for that; if you want full local control at a one-time price ($49 lifetime, $19 for the first 100 founders), MLD is designed for that slot.

Frequently asked questions

Does MLD sync my library between my home and studio computers?

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.

Do I need Dropbox or Google Drive for MLD?

No. MLD has zero cloud dependencies. You install it, it reads your local libraries, you use it offline.

Is there a monthly subscription?

No. MLD is a one-time purchase — currently $49 lifetime, with the first 100 founders at $19 lifetime. Auto-updates continue after purchase.

Does my library data leave my computer?

No. Every scan and every write is local. MLD's own database is encrypted with SQLCipher, and music files themselves never leave the machine.

Which DJ software does MLD support?

Rekordbox (including encrypted 6+ master.db), Serato DJ Pro & Lite (native `%%` crate hierarchy), and VirtualDJ Home & Pro (portable and shared installs, Favorite Folders included).

What about mobile?

MLD is desktop-only (macOS + Windows). There's no iOS or Android companion — library work happens where the DJ software runs.

Does MLD have a free tier?

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.
