Is GraphHopper a tile server too?

Hello, I want to embed a map into a desktop application that will not have internet connection. I have tried GraphHopper with a .pbf file and it works with the routing API off-line, but if I go to localhost:8989 without internet connection it does not show anything in the region of the pbf file I am using.
So, how can I embed an off-line map?

GraphHopper is a routing library, is not related to map engines.

To build a desktop application with offline maps, can check map libraries like Mapsforge or OpenGL VTM, both compatible with Mapsforge offline maps.
