I Built a Global Location Data API with 12M+ Cities — Here's How

A developer launched LocalityAPI, a global location data API for place, postal code, and timezone lookups.

The service was built as a cheaper, more reliable alternative to costly or hard-to-host options like Google Maps Platform and Nominatim.

LocalityAPI uses PostgreSQL, PostGIS, FastAPI, and Redis, and supports search, autocomplete, postal lookup, nearby queries, and country data.

It includes confidence scores for records and is designed to return fast responses for common location-data tasks.
