Open Source
GraphHopper invests in an active open source community. Our flagships are the GraphHopper routing engine and jsprit, the toolkit for solving rich vehicle routing problems. We promote a fair & diverse mindset.
Optimization Engine jsprit
jsprit is a Java based toolkit for solving rich traveling salesman problems (TSP) and vehicle routing problems (VRP). It is lightweight, flexible, easy-to-use, and based on a single all-purpose meta-heuristic.
GraphHopper Routing Engine
The GraphHopper routing engine is fast and memory-efficient, using Java. It runs server side, offline on Android and iOS. It uses OpenStreetMap data, but can import other data sources as well.
OpenStreetMap
GraphHopper is a gold corporate member of the OpenStreetMap Foundation. We provide our route planning for free on the official openstreetmap.org website.
