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.; onX Maps hunt, Offroad and Backcountry are entirely separate subscriptions, so a user needing more than one activity pays for more than one product with no combined bundle discount.
- They diverge on capability: Fused covers User defined functions, onX Maps covers Land ownership boundaries.
- 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 onX Maps
- An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot onX Maps
- 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 onX Maps
- A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot onX Maps
onX Maps
- A hunter who needs to know exact private and public land boundaries before crossing onto a propertynot Fused
- An off-road driver planning a trail route with land ownership and access datanot Fused
- A backcountry skier or hiker wanting offline terrain maps without cell signalnot Fused
- Someone who does two or more of these activities and needs to budget for two or three separate subscriptionsnot 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.
onX Maps
- Hunt, Offroad and Backcountry are entirely separate subscriptions, so a user needing more than one activity pays for more than one product with no combined bundle discount.
- Elite-tier pricing at roughly $99.99 a year per product is expensive if a buyer only occasionally needs the private land ownership data it adds.
- The apps are US and Canada focused, with more limited usefulness for international travel compared to a global mapping product.
- Land ownership data, while extensive, can lag real-world changes in property boundaries in fast-changing areas.
- It is not a general-purpose hiking or trail-review app in the way AllTrails or Gaia GPS are, so casual hikers without a land-boundary need may find the focus narrower than expected.

Questions people ask
- Is Fused or onX Maps better?
- Neither clearly leads. Fused starts at Free and onX Maps at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Fused or onX Maps?
- Fused has a free tier; the other does not. Paid plans start at Free for Fused and On request for onX Maps.
- Does Fused or onX Maps run on more platforms?
- Fused runs on Web, Linux, macOS, Windows. onX Maps runs on iOS, Android, Web.
- Can I use Fused for free?
- Yes. Fused has a free tier, so you can try it without paying. onX Maps 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 onX Maps is typically brought in for.
- What can Fused do that onX Maps cannot?
- Fused covers User defined functions, Instant tile endpoints, HTTP API, Caching. onX Maps covers Land ownership boundaries, Offline maps, Waypoint and track marking, Elite tier private land data.
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.
onX Maps: Can I use one onX subscription for both hunting and off-roading?
No, onX Hunt, onX Offroad and onX Backcountry are separate apps with separate subscriptions.
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.
onX Maps: What does the Elite tier add?
Elite tiers add nationwide private land ownership data, more recent satellite imagery and partner discounts on top of the base Premium tier.
Fused: Can I run UDFs locally?
Yes, through the Python SDK, which is how most development is done before deploying.
onX Maps: Does onX work outside the US?
Coverage is strongest in the US and Canada; usefulness elsewhere is limited.
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.
