Music Tools is a web app for creating smart Spotify playlists. The app is based on `spotframework <https://github.com/Sarsoo/spotframework>`_ and `fmframework <https://github.com/Sarsoo/pyfmframework>`_ for interfacing with Spotify and Last.fm. The app is currently hosted on Google's Cloud Platform.
The system is composed of a Flask web server with a Fireo ORM layer and longer tasks dispatched to Cloud Tasks or Functions.
