Leaflet was developed by Vladimir Agafonkin of MapBox, which is a building-block application that makes it easy to integrate location into mobile applications.
Leaflet works efficiently across all major desktop and mobile platforms out of the box, taking advantage of HTML5 and CSS3 on modern browsers while being accessible on older versions as well.
