The short version

  • Only deck.gl has a free tier, so it costs nothing to try first.
  • Each has a real cost: deck.gl open source framework with no commercial support tier available; support relies on community and GitHub issues; 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: deck.gl 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.

deck.gl

  • Open source framework with no commercial support tier available; support relies on community and GitHub issues
  • Maintained by community contributors (vis.gl contributors), not by a dedicated company support team

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

deck.gl: How much does deck.gl cost?

deck.gl is completely free to use. It is an open source framework maintained by the OpenJS Foundation and community contributors. The project is available on GitHub for anyone to use, modify, and contribute to without cost.

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.

deck.gl: Is deck.gl open source?

Yes, deck.gl is open source software maintained by the OpenJS Foundation and vis.gl contributors. The source code is publicly available, and the framework can be used freely in any project.

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.
