What Modest Maps is
Modest Maps is a free library for designers and developers who want to add interactive maps to their projects. It supplies core mapping features and hooks that developers can use to extend the library, rather than trying to provide every map control or layer type. The JavaScript library is listed as compatible with Firefox, Chrome, Opera, iOS, Android, and Internet Explorer 7–9. Its modestmaps.min.js file is 10KB minified and gzipped. A site example uses a templated Mapbox tile URL to make a map layer. The project also lists implementations or utilities for Python, ActionScript 3, Cinder, Processing, PHP, and OpenFrameworks. Script embedding and API access are listed. The library is free, with no plan limits stated, and no free trial. The homepage credits Stamen, Bloom, and MapBox as contributors.
