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)

SYSTEM REQUIREMENTS

CPU: Quad-core or better, ~2018+ (e.g. i5/Ryzen 5 class, 4C/8T or more)
RAM: 8 GB+
Browser: Latest Chrome or Edge (best AudioWorklet support)
Display: 1280x800px or higher resolution recommended (side-by-side decks fit well)

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.

Start mixing (about 2 minutes)

  1. Open https://www.djyan.net/djtool/ (or the Chrome extension).
  2. Click Run CDJ-WEB 100. Browsers block audio until one click or key.
  3. Deck A: LIBRARY, URL, or Load / Drop MP3.
  4. Load a second track on Deck B.
  5. X plays A, B plays B. Blend on the crossfader. Ride GAIN and EQ.
  6. Optional: AUTOCUE, jog for bend, hot cues under the waveform, ? for in-app help.
