I recently asked a similar question (which sadly got voted down): Is it possible to use non Mercator projections in Mapbox, Google Maps or any other webmap API?
Google's Mercator projection cuts off at 85 degrees because things get extremely distorted after that point.
As far as I know there are limited options for non-Mercator projections in web map APIs. Here are the best I've found so far:
Google sort of supports other projections
OpenLayers supports other projections using proj4
This open issue on Mapbox might be worth following
Cesium supports globe/ flat views
If you only need limited web map functionality then d3 could provide some options: e.g. d3-geo-projection
