| Pricing | The public server is free to use but has a strict usage policy: at most one request per second, a User-Agent or Referer that identifies your app, no bulk geocoding, and attribution to OpenStreetMap. | The public server at photon.komoot.io is free for fair use; for heavy use you can host Photon yourself, as it is open source. |

## Which one to choose

Both search OpenStreetMap data for free without a key. Nominatim is the full geocoder, from address to coordinates and back, but its public server allows one request per second and no bulk work. Photon is built for search-as-you-type: typo-tolerant and fast, which makes it the better fit for address autocomplete in a form.
