* Leaflet is based completely on the web platform. It achieves a zoomable slippy map experience by animating DOM elements - usually image tiles. * MapLibre GL JS is a BSD licensed fork of Mapbox GL JS version 1. Instead of consuming bitmap image tiles, it consumes tiles corresponding to the same coordinate extents as the above tiles, but containing tagged geometry features. So instead of sending a PNG image you're sending what is essentially an SVG, but in binary format and with some domain-specific compression. * The GL JS renderers also rasterize those vector tiles using WebGL, which means that all the geometry data exists in GPU memory and can be scaled, rotated, and recolored etc in realtime efficiently, and also implement their own limited text rendering so even labels can be rotated in realtime.
