GraphHopper Route Planner
GraphHopper is a fast and memory efficient Java road routing engine released under Apache License 2.0. Per default it uses OpenStreetMap data but can import other data sources.
GraphHopper for the Web
See GraphHopper in action on GraphHopper Maps
GraphHopper Maps uses the Directions API for Business under the hood, which provides a Routing API via GraphHopper, a Route Optimization API via jsprit, a fast Matrix API and an address search via Photon. Additionally the map tiles from various providers are used where the default is Omniscale, and all is available for free, via encrypted connections and from German servers for a nice and private route planning experience!
