The short version

  • Each has a real cost: Nominatim the public API allows an absolute maximum of 1 request per second; Zonar Systems the product is shaped around pupil transport and heavy vocational work, so light commercial van fleets pay for inspection and ridership machinery they will never use.
  • They diverge on capability: Nominatim covers Core Functionality, Zonar Systems covers EVIR.
  • Prices and features above were last checked on 31 August 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

Zonar Systems

  • The product is shaped around pupil transport and heavy vocational work, so light commercial van fleets pay for inspection and ridership machinery they will never use.
  • EVIR requires RFID tags fitted at zones on every vehicle plus a handheld or tablet, so installation labour and ongoing tag replacement are real costs that a plug-in competitor does not carry.
  • Continental has been separating its automotive divisions into standalone businesses, which leaves the long-term ownership and investment path for Zonar uncertain just as districts sign multi-year agreements.
  • The interface and reporting are dated next to newer platforms, and administrators moving from a modern dashboard find report building and data export unnecessarily manual.
  • Pricing is quoted rather than published and bundles hardware into multi-year terms, so comparing it fairly against a month-to-month competitor requires modelling total cost across the whole contract rather than the monthly figure.

Answered from the vendors’ own pages

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.

Source
Zonar Systems: What does EVIR actually prove?

That a person carrying the scanning device was physically next to each tagged zone on the vehicle in sequence. It does not prove they looked carefully, but it removes the common defence that an inspection was recorded from the cab.

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
Zonar Systems: Is Zonar only for school buses?

No. It is used across waste, utilities, construction and transit, but pupil transport is where its ridership and parent-facing features have no direct equivalent.

Zonar Systems: How disruptive is the installation?

More disruptive than a plug-in device. Expect a vehicle out of service for a fitting appointment, tags mounted at several points, and a rolling programme across the fleet rather than a same-day rollout.
