What Is OpenKeyScan?
OpenKeyScan is a free, open-source key detection application created by the developer of Lexicon (the DJ library management tool). It uses AI and Convolutional Neural Networks (CNN) for key detection accuracy that rivals Mixed In Key and surpasses built-in detection in rekordbox, Serato, and Traktor according to community testing in 2025-2026.
Its main strength is bulk batch processing: OpenKeyScan can analyze hundreds of tracks per minute, write detected key information to ID3 metadata, and update rekordbox, VirtualDJ, and Traktor databases directly. It is designed for DJs who want to prepare their entire library with accurate key tags.
The limitation: OpenKeyScan is a desktop-only download (Mac/Windows), does not detect BPM, and does not include companion tools for chord detection, delay calculation, or scale lookup. For quick individual track checks, BeatKey is faster since there is nothing to install.
OpenKeyScan Does Not Detect BPM
OpenKeyScan is a key-only detector. For DJ mixing, you also need BPM alongside key to find harmonically compatible tracks at similar tempos. BeatKey detects BPM and key together in one analysis and shows the Camelot code automatically.
Many DJs use OpenKeyScan for library prep and BeatKey for quick BPM checks on individual tracks during sessions.

What is the difference between OpenKeyScan and BeatKey?
OpenKeyScan is a desktop batch processor optimized for tagging large DJ libraries with key metadata. BeatKey is browser-based with no download required, detects BPM alongside key, and includes an interactive Camelot Wheel, Chord Finder, Delay Calculator, Scale Finder, and Note Frequency Calculator. Both are free.
Does BeatKey work with rekordbox or Serato like OpenKeyScan?
BeatKey does not integrate directly with DJ software databases. OpenKeyScan can update rekordbox, VirtualDJ, and Traktor databases in bulk. BeatKey is best for quick individual track analysis and for checking unreleased tracks, samples, and stems that are not in your DJ library yet.
Does BeatKey show Camelot codes like OpenKeyScan?
Yes. BeatKey always shows the Camelot code (e.g., 8A) alongside the musical key. BeatKey also includes a fully interactive Camelot Wheel at beatkey.app/camelot-wheel that deep-links from detection results and highlights all compatible keys for the detected Camelot code.
