Leaflet

Leaflet is a modern, lightweight BSD-licensed JavaScript library for making tile-based interactive maps for both desktop and mobile web browsers, developed by CloudMade to form the core of its next generation JavaScript API.

It is built from the ground up to work efficiently and smoothly on both platforms, utilizing cutting-edge technologies included in HTML5. Its top priorities are usability, performance and small size, A-grade browser support, flexibility and easy to use API. The OOP-based code of the library is designed to be modular, extensible and very easy to understand.
