Route Differences Between GraphHopper Maps and Self-Hosted Version

Open Source Routing Engine

Hello, I am running GraphHopper on my own server and have noticed that the generated routes differ from those on the GraphHopper Maps (https://graphhoper.com/maps) website. I am using the same config-example.yml and latest OSM data, but sometimes the chosen routes are different.

This is from localhost

A few questions I have:

  1. Are there any default parameter differences between GraphHopper Maps and the self-hosted version?
  2. Does GraphHopper Maps use additional data or special configurations that are not available by default in the self-hosted version?
  3. How can I ensure that the routes generated on my own server match those from GraphHopper Maps?

Thanks!
