Compatible with both Google Maps and Open Street Maps (OSM) for seamless integration.Client-Side rendering option gives small directories snappier maps that respond instantly.Our unique Server-Side rendering option does all the hard work on the server and passes only the necessary information to the browser. Therefore, large directories with millions of listings can still have responsive maps.Grid size and zoom levels can be adjusted, giving you granular control over how and when clustering renders.Set per map, meaning if you have multiple maps, then you can apply the clustering effect to any or all of them.
