Very neat product! I especially like your Maps app (I myself built TravelMap.net).
Are all your maps static?
Do you generate and host your OSM vector tiles yourself?

Yes, the tiles for our locator maps [0] are self-generated and hosted based on OSM source data and the OpenMapTiles project.
The boundaries used for choropleths [1] are maintained by us based on various public sources (NaturalEarthData, OSM, government data, …)
