It is developed by Vladimir Agafonkin of MapBox with a team of dedicated contributors.
Weighing just about 30 KB of gzipped JS code, it has all the features most developers ever need for online maps.
Leaflet is designed with simplicity, performance and usability in mind.
It 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 ones too.
It can be extended with a huge amount of plugins,
has a beautiful, easy to use and well-documented API
and a simple, readable source code that is a joy to contribute to.
