Attributions for open source


I need some clarification about attributions. I plan to use Graphhopper, and I see that page where it is written :

…where you utilize the GraphHopper Directions API

Do that means that if I install the Opensource version locally (available for my user), attributions are not mandatory ? (I refer to the Opensource page that explain the difference between Open source and Direction API)


The GraphHopper Directions API ‘just’ uses the open source projects and has a different license, yes. See the project pages of the open source versions for their license (Apache 2).
