Hey Product Hunt! 👋 I’m António, a DJ and producer, and the maker of Spiral DJ. Having a library full of great tracks is one thing. Deciding how to turn them into a night that makes sense is another: where to begin, when to build energy, how to connect transitions, and where to go if the room needs something different. I built Spiral DJ to help with those decisions before you reach the booth. Here’s the workflow: • Define the set’s duration, energy arc and must-play tracks. • Analyse your library for BPM, key and energy. • Shape the running order and explore alternative routes: Hold, Lift, Reset and Surprise. • Check transitions and stress-test the full set for pacing, vocal clashes and other potential weak points. • Export the running order to your existing DJ workflow, then record what you actually played. You stay in control of the musical decisions. Spiral gives you suggestions and explains the reasoning behind them. Your audio is analysed locally in your browser. No music uploads. The Free plan supports up to 500 tracks, with no card required. Pro adds an unlimited library, professional exports, a printable booth sheet, gig history and Forgotten Gems. I’d love to hear from DJs at any level: which part of preparing a set takes you the most time, and what would make it easier? Thanks for checking out Spiral DJ. I’m here for your questions and feedback.
