The free and open map API to create and share web maps based on OpenLayers.

license: 3-Clause BSD

Watch the online demo at


At the moment there are a few free map layers based on open data included in the online demo. But it is easily possible to include your own layers (e. g. WMS) in your Shareloc instance (see section Build and deploy your own Shareloc instance).

Create maps without coding via web application

With Shareloc it is possible to create your OpenLayers web map without any coding. With the Shareloc web application you can

  • configure your map view
  • add a marker to point at a special place and
  • optionally add a text in a bubble to your marker.

Afterwards you can share your map by a simple link or embed the map in your own website.

Use Shareloc JavaScript API

Shareloc offers an easy-to-use JavaScript API to create your own OpenLayers maps. Therefore you just have to include the Shareloc JavaScript lib into your HTML page. Now with a few lines of code it is possible to create a customized OpenLayers map.

var api = new Shareloc.MapApi();
var params = {
    // lon of map center
    X: 8.318049976895958,
    // lat of map center
    Y: 49.43451657605041,
    // initial map zoom level
    zoom: 14,
    // layer
    bgLayer: "osm.base"
// create and return your ol3 map instance
var olMap =;

Check out the API docs to see all possibilities Shareloc offers.
