Photon is an open source geocoder for OpenStreetMap data built on OpenSearch, supporting forward and reverse geocoding with multilingual, typo-tolerant, search-as-you-type queries. It can be self-hosted via release binaries or pre-built database dumps, and is also offered as a public demo API by komoot.
Use cases
- geocode addresses from openstreetmap data
- reverse geocode coordinates to addresses
- self-host a geocoding api for my app
- add search-as-you-type place search with typo tolerance
- filter place searches by bounding box or osm tags
- run a multilingual place name search
- import nominatim data and keep it continuously updated
When to choose
- you need a self-hosted geocoder over OSM data without usage limits
- you want multilingual, typo-tolerant, search-as-you-type place search
- you need reverse geocoding or bbox/tag filtering
- you want weekly pre-built worldwide or country database dumps
When to avoid
- you need full geometry output, which is not supported
- you lack the ~95GB disk and 64GB RAM recommended for planet-wide data
- you need a geocoder for non-OSM or commercial address data
- you want a fully managed hosted service with availability guarantees
