The short version

  • Only Lonboard has a free tier, so it costs nothing to try first.
  • Each has a real cost: Lonboard it is a notebook visualisation library, not a mapping application, so there is no editing, no layout, no map export for print and no sharing beyond distributing the notebook or an HTML file; 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: Lonboard covers GeoArrow binary transfer, Zonar Systems covers EVIR.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Lonboard

  • An analyst exploring a national road or parcel dataset in a notebook where pydeck or ipyleaflet becomes unusable at that sizenot Zonar Systems
  • A researcher publishing a reproducible analysis where the visualisation must run from the same script as the processingnot Zonar Systems
  • A data scientist joining spatial data to model outputs in pandas and needing to see the result immediately without exporting to a GISnot Zonar Systems
  • A team building an internal analysis pipeline on GeoParquet that wants rendering without a serialisation step in the middlenot Zonar Systems

Zonar Systems

  • A school district that must evidence pre-trip inspections to a state regulator and cannot rely on a driver ticking boxes on a screennot Lonboard
  • A pupil transport operation that needs to answer parent queries about which bus a child boarded and whennot Lonboard
  • A waste or utilities fleet with heavy vehicles where a missed defect becomes a liability question in courtnot Lonboard
  • A public sector fleet running a formal tender where verified inspection records are a scored requirementnot Lonboard

Where each one falls short

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

Lonboard

  • It is a notebook visualisation library, not a mapping application, so there is no editing, no layout, no map export for print and no sharing beyond distributing the notebook or an HTML file
  • Maintenance sits with Development Seed as an open source side output of a consultancy, so roadmap priorities follow client projects and there is no support contract to buy
  • Layer coverage is a subset of deck.gl, so an analyst needing a less common layer type has to drop to pydeck or write JavaScript rather than staying in Python
  • It expects data already in GeoPandas or Arrow form, which means the performance benefit depends on the rest of your pipeline being Arrow-friendly; reading a large Shapefile is still the slow step
  • Rendering happens in the browser, so very large datasets are ultimately limited by the client machine's memory and GPU rather than by the server, and a laptop will still fail on data a workstation handles

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.

Questions people ask

Is Lonboard or Zonar Systems better?
Neither clearly leads. Lonboard starts at Free and Zonar Systems at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Lonboard or Zonar Systems?
Lonboard has a free tier; the other does not. Paid plans start at Free for Lonboard and On request for Zonar Systems.
Does Lonboard or Zonar Systems run on more platforms?
Lonboard runs on Linux, macOS, Windows. Zonar Systems runs on Web, iOS, Android.
Can I use Lonboard for free?
Yes. Lonboard has a free tier, so you can try it without paying. Zonar Systems starts at On request.
What is Lonboard best used for?
Lonboard is most often used for an analyst exploring a national road or parcel dataset in a notebook where pydeck or ipyleaflet becomes unusable at that size, a researcher publishing a reproducible analysis where the visualisation must run from the same script as the processing, a data scientist joining spatial data to model outputs in pandas and needing to see the result immediately without exporting to a gis, a team building an internal analysis pipeline on geoparquet that wants rendering without a serialisation step in the middle. Of those, an analyst exploring a national road or parcel dataset in a notebook where pydeck or ipyleaflet becomes unusable at that size and a researcher publishing a reproducible analysis where the visualisation must run from the same script as the processing are not what Zonar Systems is typically brought in for.
What can Lonboard do that Zonar Systems cannot?
Lonboard covers GeoArrow binary transfer, GeoPandas input, deck.gl layers, Jupyter widget. Zonar Systems covers EVIR, Z Pass, MyView, Zonar Logs.

Answered from the vendors’ own pages

Lonboard: Why not just use pydeck?

pydeck serialises geometry to GeoJSON to reach the browser. Lonboard uses a binary GeoArrow pipeline, which is the reason it handles far larger datasets in the same notebook.

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.

Lonboard: Who maintains it?

Development Seed, a geospatial engineering consultancy, as an open source project. There is no commercial support offering.

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.

Lonboard: Does it work outside Jupyter?

It is built as a Jupyter widget. Exporting to standalone HTML is possible, but the intended environment is a notebook.

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.

Lonboard: Is it free for commercial use?

Yes, it is open source with no licence fee.
