ip.app vs Nominatim (OSM): common questions

Which is more reliable, ip.app or Nominatim (OSM)?

Both are neck-and-neck — ip.app and Nominatim (OSM) each measure 100% uptime over 90 days on our probe schedule. Reliability here is verified from our own scheduled checks; use the 30-day bars above to see which has been steadier lately.

Which is faster, ip.app or Nominatim (OSM)?

ip.app has the lower median latency in our checks — ip.app responds in 76 ms versus Nominatim (OSM) at 332 ms (P50). Tail latency (P95) is in the table above; for most workloads the median is the number that shapes how the API feels.

Do ip.app and Nominatim (OSM) need an API key?

Neither needs a paid key — ip.app is callable with no signup, and Nominatim (OSM) is keyless with a required User-Agent header. Both are quick to prototype with; rate limits still apply.

Can I call ip.app and Nominatim (OSM) from the browser?

Yes — both ip.app and Nominatim (OSM) send CORS headers over HTTPS, so front-end code can fetch either directly with no backend proxy. That makes them easy to swap in a client-side app while you compare responses.

Are ip.app and Nominatim (OSM) free for commercial use?

ip.app has unclear commercial terms, and Nominatim (OSM) is personal/non-commercial only. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
