Modest Maps is an open source JavaScript library for creating interactive mobile and web maps. It is designed to be simple, small, and fast, enabling developers to quickly and easily create interactive maps with minimal coding or configuration. It allows developers to use their own data sources or existing map API's to create beautiful maps with interactive features such as panning, zooming, and overlays. Modest Maps also provides an intuitive interface for users to customize the look and feel of the map. Additionally, Modest Maps is built to be cross-platform and can be used to create maps for any device or platform.
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.
