Leaflet is an open-source JavaScript library for creating interactive maps. It is designed with simplicity, performance and usability in mind. Leaflet allows developers to create mobile-friendly, interactive maps that can be easily integrated into web and mobile applications. Leaflet provides a simple API for creating and managing maps, markers, popups, and other map elements. It also provides many useful features such as layers, GeoJSON support, panning and zooming, and the ability to use multiple mapping services. Leaflet is compatible with most modern web browsers, including Internet Explorer, Firefox, Chrome, Safari, and Opera. Leaflet can also be used to create maps for mobile devices, such as iOS and Android.
Discontinued The project seems to be no longer developed. The latest version, 0.9.4, released in June 2013, can still be downloaded from the official website.
