The short version

  • Only Fused has a free tier, so it costs nothing to try first.
  • Each has a real cost: Foursquare Spatial Studio unfolded no longer exists as a product or a contracting entity, so buyers researching under that name find documentation, pricing discussion and comparison material that no longer applies to what Foursquare sells; 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: Foursquare Spatial Studio covers Browser rendering at scale, 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.

Foursquare Spatial Studio

  • A retail property team comparing catchment overlap between candidate sites using hexagonal aggregation rather than drive-time polygonsnot Fused
  • A telecommunications planner visualising a national dataset of measurements in the browser without building a tile pipelinenot Fused
  • An analytics team that already writes deck.gl in-house and wants a hosted environment so non-developers can explore the same datanot Fused
  • A marketing group that wants Foursquare places and movement data joined to its own customer geography in one toolnot 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 Foursquare Spatial Studio
  • An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot Foursquare Spatial Studio
  • 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 Foursquare Spatial Studio
  • A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot Foursquare Spatial Studio

Where each one falls short

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

Foursquare Spatial Studio

  • Unfolded no longer exists as a product or a contracting entity, so buyers researching under that name find documentation, pricing discussion and comparison material that no longer applies to what Foursquare sells
  • Pricing is not published at all, and because access to Foursquare datasets can be bundled into the same agreement, separating the cost of the software from the cost of the data requires explicitly asking for a split quote
  • Much of the visualisation capability exists in kepler.gl and deck.gl, which are free and open source, so the paid product must justify itself on hosting, collaboration and data rather than on rendering
  • Foursquare's core business is selling location data, which means the analytics roadmap follows what makes that data sell, and a customer using only its own data is not the priority segment
  • It is analysis and visualisation, not a spatial database or an editing environment, so organisations still need PostGIS, a warehouse or a GIS for the authoritative data and its maintenance

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.

Neither clearly leads. Foursquare Spatial Studio starts at On request and Fused at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Foursquare Spatial Studio or Fused?

Yes. Fused has a free tier, so you can try it without paying. Foursquare Spatial Studio starts at On request.
What is Foursquare Spatial Studio best used for?
Foursquare Spatial Studio is most often used for a retail property team comparing catchment overlap between candidate sites using hexagonal aggregation rather than drive-time polygons, a telecommunications planner visualising a national dataset of measurements in the browser without building a tile pipeline, an analytics team that already writes deck.gl in-house and wants a hosted environment so non-developers can explore the same data, a marketing group that wants foursquare places and movement data joined to its own customer geography in one tool. Of those, a retail property team comparing catchment overlap between candidate sites using hexagonal aggregation rather than drive-time polygons and a telecommunications planner visualising a national dataset of measurements in the browser without building a tile pipeline are not what Fused is typically brought in for.
What can Foursquare Spatial Studio do that Fused cannot?
Foursquare Spatial Studio covers Browser rendering at scale, H3 spatial indexing, Data joins, Time animation. Fused covers User defined functions, Instant tile endpoints, HTTP API, Caching.

Answered from the vendors’ own pages

Foursquare Spatial Studio: Can I still buy Unfolded?

No. Foursquare acquired Unfolded in 2021 and sells the product as Foursquare Spatial Studio. There is no Unfolded contract.

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.

Foursquare Spatial Studio: Is kepler.gl the same thing?

No. kepler.gl is the free open source visualisation library from the same original team. Spatial Studio is the hosted commercial platform built around it.

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.

Foursquare Spatial Studio: What does it cost?

Foursquare does not publish pricing. Ask for the software and the data licences to be quoted separately.

Fused: Can I run UDFs locally?

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

Foursquare Spatial Studio: Do I need Foursquare's data to use it?

No, you can load your own, but the commercial proposition is strongest for customers who also want the places and movement datasets.

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.
