OSRM is a high-performance C++ routing engine built on OpenStreetMap data, exposing services via HTTP API, C++ library, and Node.js wrapper. It provides routing, distance matrices, map matching, TSP trips, and vector tile generation.
Use cases
- compute fastest driving routes between coordinates
- snap GPS traces to the road network
- build a distance/duration matrix for many locations
- solve traveling salesman routes with a greedy heuristic
- self-host a routing API on OpenStreetMap data
- find nearest road segment to a coordinate
When to choose
- you need fast, self-hosted routing on OSM data
- you need map matching or travel-time matrices at scale
- you want an alternative to commercial routing APIs
When to avoid
- you need turn-by-turn navigation UX out of the box (pair with a frontend)
- you need real-time traffic-aware routing
- you only need simple geocoding without routing
