Spleeter Web, a self-hostable web app for music source separation. It lets you isolate the vocal, accompaniment, bass, and/or drums of any piece of music using deep learning-based source separation models. It's like moises.ai/ezstems.com but open-source.

I learned lots about building a full-stack web app ground-up as well as how to containerize the whole thing with Docker.
