Build tools and sources for developing OpenLayers based mapping applications

OpenLayers 3

OpenLayers 3 is a high-performance, feature-packed library for creating interactive maps on the web. It can display map tiles, vector data and markers loaded from any source on any web page. OpenLayers has been developed to further the use of geographic information of all kinds. It is completely free, Open Source JavaScript, released under the 2-clause BSD License (also known as the FreeBSD).

  • Download the latest release
  • Install with npm: npm install openlayers
  • Clone the repo: git clone

OpenLayers runs on all modern browsers that support HTML5 and ECMAScript 5. This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, polyfills for requestAnimationFrame and Element.prototype.classList are required, and using the KML format requires a polyfill for URL.
