So what to use if I want to self host a Google Maps alternative based on #OSM?
Looking for not just a map frontend library but ways to manage my own private POI collections, possibly import and visualize gpx tracks. Not interested in car routing.
Desktop app(s) would also be ok, but I'm not sure if I want to learn QGIS just to manage and visualize my collections of places and tracks.
@moreentropy if you want to self host, or even open to an alternative provider, try #umap.
