Earthwalker

Earthwalker is a game of a similar concept to GeoGuessr. You get dropped somewhere in the world in Google Street View, and the goal is that you find out where you are, and guess better than all of your friends. You can play against time, restrict the game to an area, and more.

It’s free and open source, and the idea is that people host it themselves to play with their friends. No Google API keys are needed, as Earthwalker “fools” the public Google Street View a bit. This is technically against Google TOS, so I am not hosting a public version of this myself.
