The short version

  • Only Fused has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fused the price steps are brutal: $20 to $200 to $2,000 a month with no intermediate tier, so a two-person team that outgrows Starter faces a tenfold increase for what is often a modest capacity gap.; 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: Fused covers User defined functions, 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.

Fused

  • A data team that wants to publish a dynamic layer computed from a large Parquet dataset without standing up and operating a tile servernot Zonar Systems
  • An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot Zonar Systems
  • An application that needs a geospatial computation exposed as an HTTP endpoint, where the alternative is a container, a queue and an on-call rotanot Zonar Systems
  • A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot 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 Fused
  • A pupil transport operation that needs to answer parent queries about which bus a child boarded and whennot Fused
  • A waste or utilities fleet with heavy vehicles where a missed defect becomes a liability question in courtnot Fused
  • A public sector fleet running a formal tender where verified inspection records are a scored requirementnot Fused

Where each one falls short

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

Fused

  • The price steps are brutal: $20 to $200 to $2,000 a month with no intermediate tier, so a two-person team that outgrows Starter faces a tenfold increase for what is often a modest capacity gap.
  • Published tiers do not state the actual compute, storage or request allowances, so the only way to know whether $200 covers your workload is to run it and find out.
  • Fused is at pre-seed stage with a small team, and putting a customer-facing map behind a startup’s serverless platform is a continuity risk that a procurement review will flag.
  • It is Python-only and assumes competence with cloud-native geospatial formats; there is no path for an analyst who works in a desktop GIS and not in code.
  • Serverless execution means cold starts and per-tile latency on uncached views, so a first load of a heavy UDF over a wide area is noticeably slower than a pre-rendered tile set.

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 Fused or Zonar Systems better?
Neither clearly leads. Fused 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, Fused or Zonar Systems?
Fused has a free tier; the other does not. Paid plans start at Free for Fused and On request for Zonar Systems.
Does Fused or Zonar Systems run on more platforms?
Fused runs on Web, Linux, macOS, Windows. Zonar Systems runs on Web, iOS, Android.
Can I use Fused for free?
Yes. Fused has a free tier, so you can try it without paying. Zonar Systems starts at On request.
What is Fused best used for?
Fused is most often used for a data team that wants to publish a dynamic layer computed from a large parquet dataset without standing up and operating a tile server, an analyst prototyping against overture, sentinel or census data who needs a working map in an afternoon rather than a data engineering ticket, an application that needs a geospatial computation exposed as an http endpoint, where the alternative is a container, a queue and an on-call rota, a consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tiles. Of those, a data team that wants to publish a dynamic layer computed from a large parquet dataset without standing up and operating a tile server and an analyst prototyping against overture, sentinel or census data who needs a working map in an afternoon rather than a data engineering ticket are not what Zonar Systems is typically brought in for.
What can Fused do that Zonar Systems cannot?
Fused covers User defined functions, Instant tile endpoints, HTTP API, Caching. Zonar Systems covers EVIR, Z Pass, MyView, Zonar Logs.

Answered from the vendors’ own pages

Fused: What does Fused actually give me?

A Python function becomes a map tile endpoint and an HTTP API on managed infrastructure, with caching, without you running a server.

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.

Fused: How much does it cost?

Free, then $20, $200 and $2,000 per month for Starter, Developer and Professional. Usage allowances are not itemised publicly.

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.

Fused: Can I run UDFs locally?

Yes, through the Python SDK, which is how most development is done before deploying.

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.

Fused: Does it replace PostGIS or BigQuery?

No. It reads from them. Fused is the compute and serving layer, not the store.

Fused: Is it a mature company?

No. It is a small pre-seed San Francisco company. The technology is real; the vendor risk is real too.
