British English speakers might be looking for fliers and pamphlets advertising OSM instead.

Leaflet is a modern open-source JavaScript library for mobile-friendly interactive maps, a popular option for deploying your own Slippy Map.


It is developed by Vladimir Agafonkin, previously with CloudMade but is now employed by Mapbox, with a team of dedicated contributors. It is much less complicated than OpenLayers and instead focuses on performance, usability, simple API, small size and mobile support.

It is used for the main OSM website map, as well as on Flickr, Wikipedia mobile apps, foursquare, craigslist, IGN, Washington Post, The Wall Steet Journal, Geocaching.com, City-Data.com, StreetEasy, Nestoria and Skobbler among others.
