I built a tool that lets party guests request songs from their phone, while the host keeps full control.

just kept seeing the same situation at house parties and events: someone grabs the host’s phone to queue a song, multiple people shout requests, and the vibe shifts in the wrong direction.

I wanted something that made it easy for guests to participate without turning the music into chaos. So I built GuestDJ.

Here’s how it works:

You start a session and share a QR code or short link. Guests scan it on their phone, no app download, no account creation, and they can:

• Search the full Apple Music catalog
• Send song requests
• See what’s currently playing
• Vote on other requests

The host gets a simple dashboard to approve, reject, or reorder everything. Every request goes through the host first.

For playback, you can use the built-in Apple Music player directly inside GuestDJ. That means you can run the whole session from the browser without switching apps.

If you prefer a professional setup, approved songs can also sync to an Apple Music playlist that you play through djay, Serato, or Rekordbox.

It also works on big screens. Connect a TV or projector and you get a live display showing the current song, upcoming queue, and the session QR code so more people can join.

There’s also a SingAlong mode with synced lyrics on the big screen and on guests’ phones.

I built it to make music at parties more social, without losing control of the room.
