One-pass migration from Serato crate files into Mixxx mixxxdb. Crates and folder-based browsing preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Serato DJ to Mixxx normally means an XML round-trip: export from Serato DJ, hope Mixxx parses it correctly, manually rebuild crates and folder-based browsing, discover cues didn't translate. Paths live in two places at once — the main Serato DB and every individual .crate file — so any reader that touches only one ends up half-broken. And on the destination side: Mixxx supports its own crate format that doesn't map 1:1 with playlists — writers have to choose which model is the target.

Serato DJ and Mixxx speak completely different languages: Serato crate files (Smart Crates are rule-based queries, not static lists — they have no direct equivalent in most other apps and need to be snapshotted at transfer time) versus Mixxx mixxxdb (Mixxx is open source and free, so it's often the destination for DJs leaving paid apps — but the migration tooling around it is thin). XML export-import is the usual bridge — and it's lossy on both ends. MLD treats both formats as first-class, reads Serato DJ's structure natively, and writes Mixxx's native format directly, so crates and folder-based browsing survives and the target app doesn't re-import anything. A timestamped backup of each app's library is taken before any write.
Yes. MLD reads both libraries locally, so both apps (or at least their library files) must be accessible on the same computer. Nothing uploads anywhere — all scanning is local.
Yes. MLD reads %% separator encodes nested crate folders and writes crates and folder-based browsing natively so the structure survives the migration.
Run Fix Missing Tracks for Serato DJ first. MLD scans your drives, matches moved/renamed files, and repairs links in Serato DJ before the transfer — so Mixxx receives a clean library.
Yes. Serato DJ and Mixxx libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Mixxx to Serato DJ guide. MLD supports every direction between supported apps.
Smart Crates are rule-based queries, not static playlists. MLD snapshots them at transfer time to regular Mixxx playlists, since Mixxx has no direct equivalent.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
