Local-first, one-time price, multi-DJ-app native — Music Library Doctor covers the same core ground without subscriptions or cloud dependencies.
Lexicon is one of the best-known commercial DJ library managers, with a broad feature surface and a price tag to match. 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 support you may never use. 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.

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 extra app surface to pay for. The tradeoff: you get a one-time lifetime price, all writes happen locally, nothing ever leaves your machine, and the local database is SQLCipher-encrypted. If broad multi-app scope is the most important thing for your workflow, a heavier tool will fit better. 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.
MLD focuses on Rekordbox, Serato, and VirtualDJ — the three most common home + club combinations. Traktor and Engine DJ aren't in current scope.
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 a hard requirement, you'll need a different category of tool; if local-only is a requirement, MLD is built for it.
MLD layers exact hashing, confidence-tiered metadata matching, and opt-in acoustic fingerprinting (borderline matches flagged for review instead of auto-grouped), plus a per-copy audio Quality Check. Playlists are re-pointed to the kept copy 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 — a one-time lifetime license, paid once.
Yes, natively. No downgrade, no third-party decryption helper.
Free tier covers scanning and detection. Pro is a one-time lifetime license — paid once, no subscription. Current founding pricing is on the homepage.
