PLAYLIST

Drag by the grip onto Deck A / Deck B
  • Playlist empty — add tracks above, then drag or use A / B to load a deck.

Hold PFL to solo a deck in the browser. Vinyl spins while playing. Drag a channel vinyl platter in a circle to scrub audio. Either deck near end triggers auto mix to the other deck; an empty incoming deck loads the first playlist track. Use A / B buttons on playlist rows to load a deck.

DJ7X

The free YouTube DJ mixer for parties, streams, and hangouts

DJ7X is a browser-based DJ desk for YouTube. Drop two YouTube links into the decks, crossfade like a real DJ, and let the auto-mixer keep your house party rolling. No software to install, no account to make, no fees.

Two YouTube decks

Independent transport, master volume, and a vinyl-style artwork display per deck. Paste a URL, drag a clip from the playlist, or drop a YouTube link straight onto a deck.

Crossfader + Auto Mix

Drag the central fader for hands-on blending or hit Auto Mix to crossfade automatically over 4, 8, or 16 seconds. The incoming deck starts on cue.

Equal-power crossfade

DJ7X uses a cos/sin equal-power curve so the perceived loudness stays steady through the transition instead of dipping in the middle.

Playlist with auto-advance

Queue tracks below the mixer; when Deck B finishes, DJ7X auto-mixes back to Deck A and slides the next playlist track onto Deck B for you.

PFL cue preview

Hold PFL on a deck to solo it in your browser — useful when you are deciding which track to bring in next.

Browser only, free, no signup

Everything runs in the tab. No account, no API key, no payment, no install. Open the page and start DJing.

How to DJ a YouTube party in 5 steps

  1. 1

    Open dj.7x.network

    The desk loads instantly. Two decks on top, the channel strips and crossfader in the middle, your playlist underneath.

  2. 2

    Drop your first track on Deck A

    Paste a YouTube URL into Deck A and press Play. The vinyl spins, the green Play pad lights up.

  3. 3

    Cue up the next track on Deck B

    Paste a second YouTube URL into Deck B and leave it paused. Optionally set a Start time so it joins on the drop.

  4. 4

    Press Auto Mix

    DJ7X starts Deck B and crossfades from A → B over 8 seconds (or 4 / 16). You can also drag the crossfader manually whenever you want.

  5. 5

    Stack a playlist

    Add more YouTube URLs to the playlist below. When Deck B ends, DJ7X auto-mixes back to A and queues the next track on B. Your party runs itself.

Why volume crossfade only?

YouTube audio plays inside a sandboxed iframe so a web page cannot apply EQ, filters, beatmatching, or pitch shifting to that stream. DJ7X focuses on the cleanest legal blend a browser can do: an equal-power volume crossfade that keeps perceived loudness steady through the transition. If you need full DJ controls (EQ, hot cues, pitch sync, recording), reach for a desktop tool like rekordbox, Serato, or VirtualDJ — DJ7X is built for the moments when you just want to throw on a YouTube party.

Frequently asked questions

Is DJ7X really free?

Yes. DJ7X is 100% free with no ads, no signup, no API key, and no download. Open the page and start mixing.

Can I crossfade two YouTube videos at the same time?

That is exactly what DJ7X does. Two YouTube decks share an equal-power crossfader so you can blend tracks the way a DJ would.

What is Auto Mix?

Auto Mix moves the crossfader from the deck you are on to the other deck over a chosen duration (4, 8, or 16 seconds) and starts the incoming deck for you. It is the easiest way to host a hands-off YouTube party.

Will it work on mobile?

Mobile browsers throttle background audio aggressively. DJ7X works best on desktop in Chrome, Edge, Brave, or Safari with the tab in the foreground.

Why no EQ or beatmatching?

YouTube audio plays inside a sandboxed iframe, so a web page cannot reach the underlying audio stream for EQ, filters, pitch, or tempo. DJ7X focuses on the cleanest thing the browser can do: an equal-power volume crossfade.

Can I save or share my playlist?

Right now playlists live inside the open tab. Persisted playlists and shareable mix links are on the roadmap.

Can I record the mix?

No, because the audio never leaves YouTube's iframe sandbox. To stream a set, screen-share the tab in OBS or Zoom and let your meeting/streaming tool capture system audio.
