Routing Engine

OSRM vs GraphHopper: Routing Engine Benchmarks & RAM Answer-first: Comparing OSRM and GraphHopper shows OSRM excelling in raw speed (<2ms single queries, <20ms 100x100 matrix) via C++ Contraction Hierarchies and Linux POSIX shared memory (mmap), while GraphHopper provides flexible Java-based runtime Custom Models, turn restrictions, and multi-profile vehicle fleets. For static ride-hailing matrices, choose OSRM; for heterogeneous delivery fleets with weight/height limits, choose GraphHopper. Introduction: When Do You Outgrow Cloud Route APIs? Building early-stage logistics applications with cloud routing APIs provides immediate reliability, accurate ETAs, and zero infrastructure maintenance. However, when daily traffic exceeds 100,000 requests or requires massive distance matrices for vehicle route optimization, proprietary API costs explode while rigid routing profiles prevent injecting custom fleet constraints. ...

GraphHopper Distance Matrix: API & OSM Hosting Guide Answer-first: GraphHopper distance matrix is a high-performance open-source routing engine endpoint that calculates travel times and road distances for N×M origin-destination coordinate pairs using OpenStreetMap data. By utilizing Contraction Hierarchies and memory-mapped graphs, self-hosted GraphHopper evaluates a 100×100 matrix in under 52ms, providing 99.7% cost savings over commercial APIs with runtime vehicle customization. How to Call the GraphHopper Matrix API (/matrix Endpoint) Running GraphHopper distance matrix in production requires configuring Docker deployment, the /matrix API endpoint, Custom Models for vehicle-specific routing (truck/motorcycle), H3-based Redis caching, and evaluating performance tradeoffs against OSRM, Valhalla, and Google Maps (for an in-depth analysis of routing engine selection, see our OSRM vs GraphHopper Architecture Comparison). ...
