Data Sources
PitStopper integrates with a range of APIs and data providers to deliver POI data, map tiles, elevation profiles, fuel prices, and more. Some services run on our own servers, while others are third-party public APIs accessed directly from your browser.

We are truly thankful for the communities involved in contributing data to both the OpenStreetMap and Wikipedia projects. Without the countless volunteers who map, edit, and maintain these open datasets, PitStopper and many other projects simply would not exist. Thank you.
