Qwant Maps: opensource and privacy-preserving map

Thus Qwant Maps uses OpenStreetMap data to generate its own vector tiles, its own base map, its own web APIs. Also Qwant Maps feeds its geoparsing web service as well as its online applications thanks to OpenStreetMap data. All components developed by Qwant Maps are open source so that users can contribute directly to improve their experience with the map: they can contribute either to the Qwant Maps code or to the enrichment of the data directly in OpenStreetMap.
