Beat.Tools as a Mixed In Key alternative
Mixed In Key is the reference for DJ key detection — at around US$58, installed on the desktop. Beat.Tools covers the same crate-prep flow (Camelot, energy, cues, Rekordbox export) right in the browser, free while in preview, with analysis running on your device.
Analysis runs 100% in the browser. In offline mode, your audio never leaves your computer.
Where Beat.Tools covers the flow
For typical crate prep:
- Camelot key (average and fractional) and BPM on-device
- Energy 1–10 for the set's arc
- Cue points and beat grid
- Writes TBPM/TKEY into MP3s and exports Rekordbox XML, M3U, CSV
- Extras MIK doesn't have: HPSS stems to audition transitions, and zero install
Where Mixed In Key still wins
Honesty first: MIK has over a decade of key-detection refinement, offline queues for batches of thousands of tracks, and mature desktop integrations. If your workflow depends on those today, it remains the safe choice. We don't claim to be 'better' — we cover the same prep, in the browser and for free, so you can test at no cost.
How to test in 5 minutes
Open Beat.Tools, pick 3 tracks you know by ear, compare key and BPM against what you already have. If they match, run the whole crate and export to Rekordbox. No account, no card, no upload.
Frequently asked questions
Is Beat.Tools really free?
Free in preview, with unlimited local analysis. If anything becomes paid later it will be account features (sync, batch export) — local analysis stays on your device.
Is the detection as good as MIK's?
MIK is the market reference. Our detection outputs average and fractional Camelot, and we recommend comparing against tracks you know before switching your workflow.
Does it have energy like MIK?
Yes, a 1–10 scale per track, computed locally.
Does it work with Serato or Traktor?
The official exports today are Rekordbox XML, M3U, CSV and TBPM/TKEY tags on MP3. ID3 tags are read by virtually every DJ software.
