Mapnik webfrontend for custom mapstyles
TileMill (tilemill.com) was a design environment developed by MapBox for cartography, constituting Mapnik as a renderer, CartoCSS as a stylesheet language, and a locally-served web interface with node.js as a server and based on Backbone.js for the client. Since version 0.9.0, the web server is wrapped with a native GUI on all supported platforms.
By default TileMill renders to an MBTiles file, an SQLite bundle of tile images that enables compression and faster transfers. PNG and PDF output is also supported for static maps. Mercator is the main supported projection.
As of 2015, TileMill is no longer under active development by Mapbox, which replaced it with another open source application called Mapbox Studio.  An alternative to Tilemill is the open source project Kosmtik.
