What OpenLayers is

OpenLayers is a JavaScript library for placing dynamic maps in web pages. It can combine tiles from OSM, Bing, MapBox, Stadia Maps, other XYZ sources, OGC mapping services, and untiled layers. Vector data can be rendered from GeoJSON, TopoJSON, KML, GML, Mapbox vector tiles, and other formats. Canvas 2D and WebGL rendering are available, with mobile support included out of the box. Developers can style maps with CSS, extend them through the API or third-party libraries, and create custom profiles from selected components. Listed integrations include Cesium, Mapbox styles, Google Maps, ArcGIS REST services, React, Vue, and STAC. The recommended installation is the `ol` npm package. OpenLayers uses the 2-clause BSD License and is listed as free, with no paid tiers stated. Its API remains stable within each major release series.
