Valhalla is an open source routing engine and set of libraries built on OpenStreetMap data, written in C++. It provides turn-by-turn directions, time/distance matrices, isochrones, elevation sampling, map matching, and traveling-salesman tour optimization.

Use cases

  • compute driving, walking, or cycling directions from OpenStreetMap data
  • generate isochrones showing reachable areas by time or distance
  • build a self-hosted alternative to Google Maps routing APIs
  • calculate origin-destination time and distance matrices
  • match GPS traces to road networks
  • solve traveling salesman tour optimization
  • sample elevation along a route

When to choose

  • you need a self-hosted, open source routing engine with permissive MIT licensing
  • you want advanced features like isochrones, map matching, and multi-modal routing in one tool
  • you work with OpenStreetMap data and need tiled, scalable routing
  • you need a high-performance C++ engine with Python bindings

When to avoid

  • you only need simple point-to-point geocoding without routing
  • you want a hosted managed service with no infrastructure to run
  • you need routing for proprietary map data sources not supported by Valhalla's tooling
