Keys prepares the music.
ABYZOR One presents you.

ABYZOR One — creator platform Free

The other half of a DJ's workflow isn't software — it's the page a promoter opens when they're deciding who to book. ABYZOR One gives you a real one: a custom URL, your mixes and releases, a photo gallery and a one-tap booking contact. It takes about five minutes and costs nothing.

  • Custom URL at one.abyzor.space/you
  • Releases, gallery, social and streaming links in one place
  • One-tap booking / contact CTA
  • Free forever — nothing to install

One is a separate, optional part of ABYZOR. Keys works fully without it, and nothing in your library is uploaded anywhere.

DJ and producer?

Play your own tracks. Make them first.

Half the people who prep libraries also write the music in them. Genesis generates the first idea for free; Variations develops it into a finished arrangement — then Keys analyses the result like any other track.
