Openrouteservice is an open-source, Java-based routing service built on a fork of GraphHopper that consumes OpenStreetMap data. It exposes APIs for directions, isochrones (reachability areas), time/distance matrices, snapping, and graph export, and can be self-hosted or used via the hosted API.

Use cases

• calculate driving, cycling, or walking directions from openstreetmap data
• generate isochrones to analyze areas reachable within a time or distance limit
• compute many-to-many travel time and distance matrices
• self-host a route planning API on my own servers
• snap coordinates to the nearest road network
• export the routing graph for spatial analysis
• run accessibility analysis like distance to healthcare facilities

When to choose

• you need a customizable, self-hosted routing engine based on OpenStreetMap
• you need isochrone or matrix computations at scale without per-request fees
• you want an open-source alternative to commercial routing APIs like Google Directions
• you need multiple transport profiles (car, bike, foot, wheelchair) from one API

When to avoid

• you only need simple turn-by-turn navigation in a mobile app with no customization
• you cannot provision the RAM and processing power needed to import large OSM extracts
• you need real-time traffic-aware routing from proprietary data sources
• you want a lightweight library to embed in-process rather than a standalone service
