Thanks for the question! I&#x27;ll admit I have limited knowledge about those services, but I believe they solve a slightly different problem. Pathfinder&#x27;s primary use is services that have N drivers that can service any of M transportation requests.<p>The GraphHopper and OSRM Matrix APIs are closer to what Pathfinder does, however they do not assign route segments to vehicles. Pathfinder is perhaps one abstraction layer over them.
