OpenLayers

OpenLayers is a high-performance, feature-packed JavaScript library that simplifies integrating dynamic maps into web pages. It is an entirely free and Open Source solution, released under the 2-clause BSD License, making it accessible for developers worldwide to display geographic information of all kinds. The library empowers users to effortlessly render map tiles, vector data, and markers sourced from a multitude of providers.

The library offers robust support for tiled layers, allowing integration with popular sources such as OpenStreetMap, Bing, MapBox, and Stadia Maps, alongside OGC mapping services. It also excels in vector layers, enabling the rendering of geospatial data in formats like GeoJSON, TopoJSON, KML, GML, and Mapbox vector tiles. This comprehensive data handling makes it a versatile tool for various mapping applications.

Built with cutting-edge web technologies, OpenLayers leverages Canvas 2D, WebGL, and HTML5 features to deliver a fast and mobile-ready experience out of the box. Its architecture supports building lightweight custom profiles by including only necessary components. Furthermore, it is easy to customize and extend, with map controls styleable via CSS and an API designed for integration with third-party libraries.
