Why geolith

A geocoder that is one file.

One file, no database

The whole index is one static .glx file read with HTTP range reads. No Elasticsearch, no PostGIS, no import that takes a day.

Open data you can keep

OpenStreetMap plus Overture Maps. Store results permanently on every plan, with one attribution line.

Bills you can predict

Flat monthly plans from $0 to $299. Over quota, requests stop with HTTP 429; there is no overage charge.

Measured, not claimed

Benchmarked against Nominatim, Photon and Pelias on the same data, with the method published.

Planet file measured 22 Oct 2026. The hosted API at api.geolith.app answers from this file, worldwide.
