Comparison
Mixgraph scores how well any two tracks mix — chemistry — and puts that score where you work: the set you plan mid-week, the next track you reach for in the booth, and the new music that lands each Sunday. Most of the tools below do a different job. Here is the honest version of where each one sits.
The short version
Every tool below is good at the job it was built for. Only one of them is built to answer what comes next.
What it is
Analysis software for Mac and PC. It reads the key, BPM and an energy level off the files on your drive and writes them back into your tags — Camelot code in the key field, energy in the comments — so your collection arrives in rekordbox or Serato already labelled.
Where Mixgraph differs
That tells you what each track is. Mixgraph tells you what to play after it: chemistry scored on the pair, across harmony, rhythm, energy, groove, mood and vocals, in the direction you are actually mixing.
Run both?
Run both. Tags written on disk, set decided before you get to the booth.
What it is
A web database of key, BPM and Camelot codes built on Spotify data, plus a row of free tools — analyse your own files, tap a tempo, shift key or tempo, strip vocals. It will also show you related tracks.
Where Mixgraph differs
Both of us hand you a list. The difference is what the list is ranked on. Tunebat groups tracks that share attributes; Mixgraph scores the transition between one specific track and the next, across six dimensions, in one direction, and shows the reason each pairing works.
Run both?
For a quick key lookup or a one-off tool, Tunebat is free and good at it. Come back when the question turns into "so what do I play next".
What it is
A desktop mix editor. Tracks on a timeline, transitions shaped with effects and automation, stems separated, and the whole thing rendered out as a finished mix or pushed straight to Mixcloud or YouTube. Its Harmonize feature will auto-order a playlist by key and tempo first.
Where Mixgraph differs
Harmonize and Flow Builder are answering the same question with different amounts of evidence — Harmonize orders on key and tempo, Mixgraph scores six dimensions and ranks on the transition itself. The bigger split is the output: DJ.Studio produces an audio file, Mixgraph produces a running order you go and play.
Run both?
Decide the order here, produce the recorded mix there.
What it is
Library management. One clean collection kept in sync across rekordbox, Serato, Traktor, VirtualDJ, Engine DJ and djay Pro, with cue points, beatgrids and playlists preserved, plus deep tag editing and smart playlists to keep it that way.
Where Mixgraph differs
Lexicon is about the state of your collection. Mixgraph is about what to do with it — chemistry on the pairs, a running order that holds, and fresh tracks that fit your sound each week.
Run both?
They barely overlap. Tidy the collection there, plan the set here.
What it is
Where most DJs already prep. Its Related Tracks panel pulls from your own collection, filtered by whatever criteria you set — a BPM range, how far off the key is allowed to be, genre, label, year, rating.
Where Mixgraph differs
That is a filter: it returns everything that matches. Mixgraph scores, then ranks — one number for how well this track goes into that one, across six dimensions, with the reason attached. And it is not limited to the tracks already on your drive, so the answer can be something you have not bought yet.
Run both?
Prep in Mixgraph, play in rekordbox. That is how most people here use it.
If the question is “what key is this”, a lookup answers it. If the question is “where do my files live”, a library manager answers it. If the question is “what should I play next, and will it actually land” — that is the one Mixgraph was built for, and it is the only question on this page that nothing else here answers directly.
Plan a chemistry-scored set
Mixgraph is a DJ set-planning tool for electronic music. It scores how well any two tracks mix — we call that chemistry — across harmony, rhythm, energy, groove, mood and vocals, and puts that score in the three places you need it: Flow Builder for the set you plan mid-week, Live Mode for the next track while you are playing, and Discovery Weekly for new music that fits your sound. It runs in the browser and as an iOS and Android app.
Mixgraph is built and run by NC Digital Limited, a UK company (number 16413452), founded by Nathan Cope — a tech house DJ who got tired of guessing what came next.
It solves a different half of the problem. Mixed In Key analyses your files and writes the key and energy into your tags. Mixgraph takes that analysis as a starting point and answers the next question — given this track, what should follow it, and how well does that transition actually work. Plenty of DJs run both.
rekordbox filters your collection down to tracks that match the criteria you set — a BPM range, a key distance, a genre. Mixgraph scores the transition across six dimensions, ranks the results, tells you why each one works, and can point you at tracks outside your collection. Most people prep in Mixgraph and play in rekordbox.
No. Library managers keep your collection tidy and synced between DJ apps. Mixgraph decides what goes next to what. You can import your Rekordbox collection so the suggestions come from tracks you actually own, and export a finished set back out as a rekordbox playlist — but Mixgraph reads your library rather than writing into your DJ database.
There is a free tier you can use without paying. Pro lifts the caps — every compatible track rather than the first handful, unlimited flows and favourites — and unlocks library import and export, the AI set builder, alternative tracks in Flow Builder, and Discovery Weekly.
