Local-first, one-time price, multi-DJ-app native — Music Library Doctor covers the same core ground without subscriptions or cloud dependencies.
Lexicon is the best-known commercial DJ library manager and covers a wide feature surface (Rekordbox, Serato, Traktor, VirtualDJ, Engine DJ). But two things push DJs to look for an alternative: price and architecture. Lifetime licenses run into the hundreds, monthly tiers pile up over a year or two, and the tool is broad rather than focused — you pay for Traktor and Engine DJ support you may never touch. If your setup is Rekordbox + Serato + VirtualDJ and you want a one-time purchase, local-only tool that does the essentials well, that's the gap.
Supported today
Rekordbox · Serato DJ · VirtualDJ (incl. Favorite Folders) on Windows 10+ and macOS (Apple Silicon + Intel).
MLD is narrower on purpose: three DJ apps (Rekordbox, Serato, VirtualDJ), one local install, one purchase. There's no cloud sync, no mobile app, no Traktor/Engine DJ surface to pay for. The tradeoff: you get a $49 lifetime price (or $19 for the first 100 founders), all writes happen locally, nothing ever leaves your machine, and the local database is SQLCipher-encrypted. If the broad multi-app scope of Lexicon is important to your workflow, Lexicon is the right tool. If you want a focused, local-only tool with a permanent license at a fraction of the price, MLD is designed for that slot.
No. Feature overlap exists — both do missing-file repair, dedupe, and cross-app transfer — but MLD is deliberately narrower (Rekordbox, Serato, VirtualDJ only), fully local (no cloud), and one-time purchase. Different priorities, different tradeoffs.
Not today. MLD focuses on Rekordbox, Serato, and VirtualDJ — the three most common home + club combinations. Traktor and Engine DJ are on the roadmap but not current scope. If you need those now, Lexicon remains the broader tool.
MLD is desktop-only (macOS + Windows). There's no mobile app. Library management lives on the machine where your DJ software runs, so that's where MLD runs.
No — by design. Every scan and every write is local, the local database is SQLCipher-encrypted, and no library data is uploaded anywhere. If cloud sync across devices is part of your workflow, that's a Lexicon strength; if local-only is a requirement, MLD is built for it.
MLD's Group Scorer ranks copies on bitrate, file size, folder location, filename quality, AND DJ-library usage (whether your Rekordbox/Serato/VirtualDJ playlists reference the file). Playlists are re-pointed to the winner BEFORE losing copies move to Trash/Recycle Bin — so nothing breaks. That DJ-library awareness is the core differentiator, regardless of which tool you're comparing to.
Yes. The free tier shows the full Library Health Score and surfaces every detected issue. Bulk fixes (missing-file repair, dedupe, folder consolidation, playlist transfer) require Pro — currently $49 lifetime, with the first 100 founders at $19 lifetime.
Yes, natively. No downgrade, no third-party decryption helper.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
