Seems to be a general-purpose mapping server of some kind.
Waarzitje.nu is a basic application for submitting and retrieving live location updates. Originally focused on OsmAnd, but basically any application that supports REST could use it.
The back-end (REST API) of this application is made with Go, the front-end mapping interface is made with modern Vue 3 and TypeScript. Because of its modular setup, it is possible to run only the back-end, only the front-end or a combination of both.
