open-geocode

About

open-geocode is a self-hosted geocoding engine written in Rust that builds on OpenStreetMap and OpenAddresses data. It supports forward, autocomplete, reverse and batch geocoding from a single memory-mapped file, so it needs no PostgreSQL or Elasticsearch. The authors report that country-scale indexes build in minutes and that it serves more queries per second than Photon and Pelias on a quarter of the memory, which lets users geocode addresses without sending them to a third party.
