The short version

  • Only Trailforks has a free tier, so it costs nothing to try first.
  • Each has a real cost: Nominatim the public API allows an absolute maximum of 1 request per second; Trailforks the free tier only allows one offline region downloaded at a time, which is limiting for a rider visiting multiple trail areas.
  • They diverge on capability: Nominatim covers Core Functionality, Trailforks covers Mountain bike trail database.
  • 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.

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

Trailforks

  • The free tier only allows one offline region downloaded at a time, which is limiting for a rider visiting multiple trail areas.
  • Pro pricing appears to be shifting toward bundling with the wider Outside+ media subscription, making the standalone price less stable and worth checking directly before buying.
  • Its focus on mountain biking means it is a weaker choice than Ride with GPS for road or gravel route planning.
  • Trail data quality depends on community contribution, so newer or less-ridden regions can have sparse or outdated information.
  • Being owned by a media company with a broader outdoor content bundle strategy introduces some uncertainty about how the standalone app product is prioritised long term.
