@robi Perhaps Cloudron could support Open Street Map, if not Graphhopper.
Sorry for reading this topic in perhaps too much of a hurry. Skimming it I focues on "map" but interpreted it as the noun, not the verb. 😄
If you don't necessarily need an actual map but more of a database I'd recommend taking NocoDB and its form view for a spin.
I'd be interested in what you come up with, for coopy reasons.
