I built this app in a little over a week as a hobby project. It uses the MusicBrainz and SetlistFM APIs to collect data on artist's concert histories, which you can then explore in an interactive map powered by MapLibre and MapTiler.
The predictions are generated by Gemini and only take into account historical data. Data is cached in MongoDB for up to 3 days which might mean that recent events are not accounted for.
You can view the source code on GitHub. If you liked this app, you can support me on Ko-Fi. Thank you!
