A Developer's Guide to Open Source Web Mapping Libraries
summary
Live demos compare Leaflet and MapLibre GL JS: Leaflet loads simple OpenStreetMap raster tiles quickly and uses many plugins, MapLibre renders vector tile layer styles with WebGL for heavier data. A hosted ArcGIS feature service of 53,466 address points forces clustering to stay responsive; querying a feature layer returns nearby features, while converting the same data to vector tiles cuts load time (author notes ~20s vs instant). Geocoding uses Nominatim geocoder and ArcGIS REST endpoints.
