GraphHopper is a fast and memory efficient open source routing library and server written in Java. Designed for the server, desktop, as well as for mobile devices.

It can make use of different algorithms such as Dijkstra, A* and Contraction Hierarchies. Due to its Apache License it is a business friendly alternative to existing routing engines and Android navigation software.
