It's a very simple alternative to Google Maps, with "geolocation" (position), "geocoding" (search) and "directions" widgets.
Most importantly, it doesn't track you in any way - so if you need some directions without creating a permanent data on Google's servers, you can just go to https://maps.voxpop.co.za.
Update July 2017: it seems the Mapbox Directions API and widget are pretty bad. I've tried using it myself and it almost always fails when looking for places in South Africa. What a shame.
