Web DJ tool for the masses

Browser-based dual CDJ & mixer

DJYAN.NET CDJ-WEB 100 is a free dual-deck DJ workstation that runs in your browser. Beatmatch, blend with a DJM-WEB 1-style mixer, use tempo and key (tone), channel EQ, effects (JET, ZIP, STEREO), hot cues, SYNC, live streams, mic, and Web MIDI controllers — powered by the Web Audio API. No download or install.

Virtual DJ Tool for the Masses
  • Dual CDJ-WEB 100 decks — jog wheels, tempo, tone, FX, transport, hot cues, SYNC
  • DJM-WEB 1 mixer — GAIN, HI / MID / LO EQ, channel faders, master, crossfader, mic
  • Load tracks — LIBRARY, local MP3 (pick or drag & drop), or URL stream
  • Hot cues 1–4 per deck (pads + keyboard; saved per track)
  • Keyboard shortcuts for live control
  • MIDI controllers — presets + learn (SC-2000 fully tested)
  • Pro multi-out — when 2+ sound outputs, route Deck A / B separately
  • Free embed for webmasters (iframe)

Shorts recording [new Feature]

CDJ-WEB 100 can record vertical Shorts clips straight from the app. Hit SHORTS, pick Deck A or Deck B, then record a real on-screen capture of that deck as a 9:16 video (1080×1920, 30 fps) with master audio — up to 3 minutes. When you stop, the clip downloads so you can drop it into TikTok, Instagram Reels, YouTube Shorts, or anywhere else. Perfect for sharing a cue, a mix moment, or a quick deck demo without a separate screen recorder.

How to start mixing (2 minutes)

  1. Open https://www.djyan.net/djtool/ in Chrome, Edge, Firefox, or Safari.
  2. Click Run CDJ-WEB 100 (browsers need one click before audio).
  3. On Deck A, use LIBRARY, URL, or Load / Drop MP3 (or drag a file onto the deck).
  4. Load a second track on Deck B.
  5. Press PLAY, blend with the crossfader, and tweak EQ / GAIN.
  6. Optional: enable AUTOCUE, use the jog for pitch bend, set hot cues under the waveform.

Deck controls (CDJ-WEB 100)

  • Tempo — speed (BPM) without changing musical key
  • Tone — key shift in semitones
  • Jog wheel — pitch bend while playing; scrub when paused; modulates focused FX
  • JET / ZIP / STEREO — stackable effects (jog sweeps JET notch / ZIP filter)
  • Hot cues 1–4 — empty = set · lit = jump · Shift = clear · saved per track
  • CUE / PLAY / SYNC — transport; SYNC matches tempo + beat phase to the other deck
  • TAP — tap tempo
  • LIBRARY / URL / Load — library · live stream · local file / drop
  • Visualizer — cycle waveform / jog visual modes

Mixer controls (DJM-WEB 1)

  • GAIN per channel, then HI / MID / LO EQ (−26 dB cut · 0 center · +6 dB boost — Pioneer-style)
  • Channel faders and master with meters
  • MIC — optional FX and talkover
  • Crossfader A ↔ B
  • RESET (next to power LED) — restore mixer defaults and clear saved mixer prefs
