One-time lifetime license, no monthly fee, no cloud dependency — Music Library Doctor covers the library-health side of what Cratehackers does, without the subscription.
Cratehackers is a polished cloud-first DJ platform with AI crate generation, Spotify-to-crate import, Record Pool integrations (DMS, BPM Supreme, Beatport, DJcity, Beatsource), and zero-knowledge encrypted cloud sync. For DJs who want all of that, it's worth the $15–30 monthly fee or the $197–297 annual plan. But many DJs don't need (or don't want) the cloud platform — they just want their existing Rekordbox, Serato, or VirtualDJ library to stop having duplicates, missing tracks, and quality problems. Paying a subscription for features they won't use is the wrong fit.

MLD is a desktop tool, not a cloud platform — that's the deliberate scope choice. You install once, pay once ($49 lifetime, $19 for the first 100 founders), and the tool runs entirely on your machine. No login, no monthly billing, no sync server holding your library hostage if you cancel. The features that overlap with Cratehackers (cross-DJ library health, deduplication, migration) are first-class. The features that don't overlap (AI crate generation from text, Record Pool sync, multi-device cloud sync) are simply absent — by design. If you want a cloud platform, Cratehackers is the right tool. If you want a one-time purchase that fixes your library on your machine, MLD is built for that slot. *Smart Upgrade is a Pro feature; you are responsible for ensuring you have rights to obtain replacement content.*
No. MLD's scope is library health (missing tracks, duplicates, paths, quality), not set-building. If AI-driven crate suggestions from text prompts are a primary need, Cratehackers is built for that and MLD isn't a replacement on that axis.
Not currently. Spotify → library matching (the Track Matcher feature) is on the roadmap. For now MLD focuses on what's already in your local library.
No. Record Pool integration is a Cratehackers strength. MLD is library-side only — it cleans what's already on your disk, not what's available to download.
No. MLD is $49 lifetime, with the first 100 founders at $19 lifetime. One-time purchase, all current and future versions, no recurring charges.
No. MLD is fully local — no login, no sync, no uploads, no cloud account. The local MLD database is SQLCipher-encrypted; music files never leave your machine.
Cratehackers is a cloud DJ workflow platform with AI features. MLD is a local DJ library audit tool with deep multi-app integration. The overlap is in library health and dedup. If you need the cloud platform features, pay for Cratehackers. If you need library cleanup for the apps already on your machine, MLD does that for less than 4 months of Cratehackers Pro.
Yes. Many DJs use MLD for local library hygiene and a cloud tool for crate-building. They solve different problems. MLD's writes stay local — nothing conflicts with a cloud platform's sync.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
