Hi Product Hunt! Demucs makes the open-source Demucs v4 models available in a browser, without installing Python, PyTorch or CUDA. Upload a track you own or have permission to process, choose 2, 4 or 6 stems, then preview the results with solo and mute before downloading. Use it to prepare karaoke instrumentals, isolate vocals for a remix, or practice drum and bass parts. Every verified account gets 15 free credits each month, with paid options for more usage. This is an independent, unofficial service at demucs.net, with no affiliation to Meta or the Demucs authors. Which stems would be most useful for your workflow? We welcome feedback on separation quality and the browser player.
