Hey Product Hunt! Solo dev and music producer here. I built AudioForges because I kept bouncing between sketchy converter sites and paid apps just to do basic things — grab a WAV from YouTube, find a track's key and BPM, split stems for a remix. So I started building my own tools, and it grew into 30+ free browser-based utilities: stem separation, key/BPM detection, transcription, format conversion, trimming, pitch shifting, a tuner and metronome, and more. No sign-up, no ads mid-workflow. Everything is free except a few GPU-heavy tools (HQ stems, long transcription) that run on credits to cover server costs. Would love feedback from any producers or DJs here — and happy to answer anything about the tech stack (Next.js + FastAPI + a lot of ffmpeg).
