The short version

  • Only Emlid Studio has a free tier, so it costs nothing to try first.
  • Each has a real cost: Emlid Studio it is free but it is not open source, so if Emlid changes direction or ends the product there is no community fork and no way to keep it maintained; Nominatim the public API allows an absolute maximum of 1 request per second
  • They diverge on capability: Emlid Studio covers RINEX conversion, 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.

Emlid Studio

  • It is free but it is not open source, so if Emlid changes direction or ends the product there is no community fork and no way to keep it maintained
  • Support is a community forum with no service level, which is a problem for a commercial survey firm that needs an answer before a deliverable deadline rather than when someone volunteers one
  • It only post-processes; there is no network adjustment, no project management, no least squares reporting suitable as a survey record, so it does not replace an office suite
  • The software exists to sell Emlid receivers, so features that matter to owners of competing hardware are unlikely to be prioritised even though third party RINEX is accepted
  • Results depend on the quality of the base data and on the user understanding fix, float and single solutions, and the interface will happily produce a poor solution without stopping an inexperienced operator

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

Yes, with no seat limit and no paid tier. Emlid makes its money on GNSS receivers.

Nominatim: Is Nominatim free?

Emlid Studio: Does it work with receivers from other manufacturers?

Yes. It accepts standard RINEX logs, so a base or rover from another brand can be processed.

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.
