Why not enhance existing solutions?

  • Often only C/C++ solutions like OSRM are fast and memory efficient
  • Java solutions then are not free like osm2po or too heavy weight e.g. the Spring&Hibernate based OpenTripPlanner project.

GraphHopper instead

  • is solid as it is based on many unit tests
  • is easy to integrate - even on mobile devices
  • is fast and memory efficient => e.g. being able to run German wide queries on Android
  • only a few dependencies which means it is also small < 5MB
  • it is business friendly via Apache License 2.0
