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 Maps uses the Directions API for Business, which provides routing and matrix routing through GraphHopper and also a fast address search via Photon. Additionally the map tiles from various Providers are used and all is available for free for a nice route planning experience!
