Vector and raster maps with GL styles. Server side rendering by MapLibre GL Native. Map tile server for MapLibre GL JS, Android, iOS, Leaflet, OpenLayers, GIS via WMTS, etc.
Fast displaying of maps is possible thanks to GPU-accelerated vector tile rendering. It originated as an open-source fork of mapbox-gl-js, before their switch to a non-OSS license in December 2020.
