## What it is
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
