The short version

  • Each has a real cost: ArcGIS Survey123 the app is free and the licensing is not: every person completing a secure survey needs a paid ArcGIS user type, so a hundred-person field programme costs tens of thousands a year before anyone counts credits.; Nominatim the public API allows an absolute maximum of 1 request per second
  • They diverge on capability: ArcGIS Survey123 covers XLSForm authoring, Nominatim covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ArcGIS Survey123

  • The app is free and the licensing is not: every person completing a secure survey needs a paid ArcGIS user type, so a hundred-person field programme costs tens of thousands a year before anyone counts credits.
  • Esri does not publish user type prices on its main pricing pages, so buyers reconstruct the cost from marketplace listings or a sales conversation, which makes budgeting an ArcGIS rollout unnecessarily opaque.
  • Credits are consumed by geocoding, storage and some analysis, and a data collection programme that generates heavy attachment volumes can burn through the bundled allowance and trigger a mid-year top-up.
  • It is useless without ArcGIS. There is no standalone deployment, so the decision to use Survey123 is really a decision to buy or keep an ArcGIS estate.
  • Form authoring splits between a web designer that is easy but limited and XLSForm plus Survey123 Connect that is capable but requires learning a spreadsheet syntax, and teams routinely start in the wrong one and rebuild.

Nominatim

  • The public API allows an absolute maximum of 1 request per second
  • Bulk geocoding must run in a single thread and cannot be distributed across machines
  • Scripts running longer than a day or on a schedule are limited to 4 requests per minute
  • Autocomplete search against the public API is explicitly prohibited
  • Systematic queries such as grid based reverse lookups and complete data downloads are prohibited
  • Reselling geocoding results or acting as an API intermediary is prohibited
  • Every request must send a valid HTTP Referer or User-Agent identifying the application, and default library headers are rejected
  • Results must be cached client side, and repeated identical queries can lead to blocking
  • Attribution to OpenStreetMap under ODbL must be displayed

Answered from the vendors’ own pages

ArcGIS Survey123: Is Survey123 free?

The app is. Using it is not, unless your surveys are public. Authoring needs a Creator licence and each person completing a secure survey needs a Mobile Worker, Editor, Creator or GIS Professional user type.

Nominatim: Is Nominatim free?

Nominatim is open source software built on OpenStreetMap data. It appears to be free to use, though commercial usage may require separate licensing or terms. Check the project repository or contact support for clarity on licensing.

ArcGIS Survey123: How much are the user types?

Esri does not list them on its main pricing pages. Public marketplace listings have shown roughly $700 a year for Creator and $400 for Mobile Worker; confirm with Esri or a distributor for your region.

Nominatim: What is Nominatim's pricing model?

Nominatim does not publish a standard pricing model on its website. As open source software, it is available for free, but commercial or large-scale deployments may require reviewing their licensing terms or contacting project maintainers.

Source
ArcGIS Survey123: Can respondents fill in a survey without a licence?

Yes, if the survey is shared publicly. Secure surveys require a licensed user type.

ArcGIS Survey123: Does it work offline?

Yes, in the mobile app, with sync when connectivity returns.

ArcGIS Survey123: Is it the same as ArcGIS Field Maps?

No. Field Maps is map-centric editing; Survey123 is form-centric. Many organisations license both, which doubles nothing because user types cover the whole app suite.
