About

DevTools Advanced  Location Override is a DevTools extension designed for web developers who need to test location-based functionality in their applications. 

It was built out of frustration that the existing DevTools location overrides only worked for a single location at a time, and only allowed you to override the latitude and longitude.

Advanced Location Override allows you to override all elements of geolocation, including accuracy, heading, speed, altitude and altitude accuracy.

There is also a powerful route simulation tool, that allows you to upload a route as a KML, GPX or GeoJSON file, and have the geolocation respond as if you were following the real route. Perfect for developing web apps that track your location over time.
