I am the developer of FacilMap, an open-source application based on the OpenStreetMap ecosystem that is useful for finding places, calculating routes and collaboratively creating shareable maps of markers, lines and routes.
It would be nice to see FacilMap available in Cloudron. FacilMap is running on Node.js and uses a MySQL or PostgreSQL database for storage. There is a Docker image available, the instructions how to use it are here.
