The short version

  • Each has a real cost: Felt felt publishes no prices for Professional or Enterprise, so buyers cannot compare against ArcGIS Online or QGIS with hosting without entering a sales process; 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: Felt covers Real-time collaboration, 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.

Felt

  • An environmental consultancy that needs a client to view and comment on survey results without installing GIS softwarenot Fused
  • A utility field crew collecting asset condition offline and syncing to the same map the office is looking atnot Fused
  • A planning department sharing a proposal map with the public where the viewer count is unpredictable and viewer seats would be uncostednot Fused
  • A team of analysts who each hold data in different formats and want one map assembled in an afternoon rather than a weeknot 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 Felt
  • An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot Felt
  • 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 Felt
  • A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot Felt

Where each one falls short

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

Felt

  • Felt publishes no prices for Professional or Enterprise, so buyers cannot compare against ArcGIS Online or QGIS with hosting without entering a sales process
  • Paid tiers are annual contract only with no monthly option, which excludes consultancies that need a tool for a single short engagement and forces them to the free non-commercial tier they are not licensed to use for client work
  • The API, JavaScript SDK and live warehouse connections are enterprise-only, so a mid-sized team that wants programmatic access has to buy the top tier rather than pay for one capability
  • Analytical depth is limited: there is no meaningful geoprocessing, topology checking or model building, so Felt sits beside a real GIS rather than replacing one
  • The Professional tier caps data processing at 25 GB a month and map views at 100,000 a month, which are easy to exceed with raster imagery or a public-facing map, and the overage terms are not published either

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

Felt: What does Felt cost?

Felt does not publish prices for Professional or Enterprise. Personal is free but licensed for non-commercial use only.

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.

Felt: Can I pay monthly?

No. Paid plans are annual contracts. There is a 7 day trial of Professional.

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.

Felt: Do viewers cost anything?

No. Viewer access is unlimited on the paid plans, which is the main reason organisations with large map audiences choose it.

Fused: Can I run UDFs locally?

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

Felt: Is there a nonprofit discount?

Yes, 30 per cent for verified United States nonprofits, and free access for verified students and classrooms.

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.
