The short version

  • Each has a real cost: Atlas.co analytical depth is a long way short of a mature GIS: there is no serious raster analysis, network analysis, topology editing or geodetic control, so complex work still goes back to QGIS or ArcGIS.; 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.
  • They diverge on capability: Atlas.co covers Browser GIS, Fused covers User defined functions.
  • 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.

Atlas.co

  • A renewables developer screening sites against constraint layers who needs an answer this afternoon and has no GIS analyst availablenot Fused
  • A planning or property team that mainly needs colleagues to view and comment on maps, where $7 viewer seats replace expensive read-only GIS licencesnot Fused
  • A consultancy producing client-facing maps and embeds without maintaining desktop GIS installs across a distributed teamnot Fused
  • An analyst with an address spreadsheet who needs geocoding, buffering and a shareable map without learning a desktop GISnot Fused

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 Atlas.co
  • An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot Atlas.co
  • 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 Atlas.co
  • A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot Atlas.co

Where each one falls short

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

Atlas.co

  • Analytical depth is a long way short of a mature GIS: there is no serious raster analysis, network analysis, topology editing or geodetic control, so complex work still goes back to QGIS or ArcGIS.
  • Geocoding and workflow runs are metered per tier, and a single large address batch can exhaust a month’s Pro allowance in one afternoon, forcing an upgrade for a one-off job.
  • The company is at pre-seed stage with roughly $2m raised and a small team, so buyers embedding it in a business process carry meaningful continuity risk.
  • Annual billing is required to get the advertised prices, which removes the flexibility that would otherwise make a young vendor a low-risk trial.
  • There is no offline or field capability at all, so any organisation whose spatial work includes data collection needs a second tool alongside it.

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.

Answered from the vendors’ own pages

Atlas.co: How much does Atlas.co cost?

Starter is free, Pro is $23 per user per month and Team is $72 per editor per month with viewers at $7, all billed annually. Enterprise is quoted.

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.

Atlas.co: Can it replace ArcGIS or QGIS?

For visualisation, light analysis and sharing, often yes. For raster, network or geodetic work, no.

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.

Atlas.co: What is the viewer seat?

A read-only seat at $7 per month on the Team plan, intended for stakeholders who consume maps rather than build them.

Fused: Can I run UDFs locally?

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

Atlas.co: Where is the company based?

Oslo, Norway. It was founded in 2021 and has raised around $2m in pre-seed funding.

Fused: Does it replace PostGIS or BigQuery?

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

Atlas.co: Is there a free tier?

Yes, Starter gives three projects, three editors and 1 GB of storage with metered geocoding and workflow runs.

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.
