The short version

  • Only Cesium ion has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cesium ion streaming is metered in gigabytes a month, so a public-facing application's cost is driven by visitor traffic you do not control, and a successful launch can blow through a tier immediately.; 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
  • They diverge on capability: Cesium ion covers 3D Tiles tiling, Foursquare Spatial Studio covers Browser rendering at scale.
  • 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.

Cesium ion

  • A survey firm delivering a photogrammetry mesh to a client as a browser link rather than a 40 GB downloadnot Foursquare Spatial Studio
  • A simulation team streaming global terrain and imagery into an Unreal Engine environmentnot Foursquare Spatial Studio
  • An urban planning department publishing a city model that planners can inspect without desktop GIS softwarenot Foursquare Spatial Studio
  • A software product embedding 3D geospatial views and needing hosted tiling rather than building a tilernot Foursquare Spatial Studio

Foursquare Spatial Studio

  • A retail property team comparing catchment overlap between candidate sites using hexagonal aggregation rather than drive-time polygonsnot Cesium ion
  • A telecommunications planner visualising a national dataset of measurements in the browser without building a tile pipelinenot Cesium ion
  • An analytics team that already writes deck.gl in-house and wants a hosted environment so non-developers can explore the same datanot Cesium ion
  • A marketing group that wants Foursquare places and movement data joined to its own customer geography in one toolnot Cesium ion

Where each one falls short

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

Cesium ion

  • Streaming is metered in gigabytes a month, so a public-facing application's cost is driven by visitor traffic you do not control, and a successful launch can blow through a tier immediately.
  • Reality modelling is billed in gigapixels a month, an unfamiliar unit that makes it hard to estimate in advance how many drone flights a plan will actually cover.
  • The free Community tier is restricted to non-commercial or open use, so a consultancy sharing a model with a paying client does not qualify regardless of how small the dataset is.
  • Team accounts cost substantially more than individual ones at the same quota, $524 against $149 on Commercial, so adding a second colleague is a large step rather than an incremental seat charge.
  • Self-hosting is available only under a custom enterprise agreement, which leaves organisations with data residency or air-gap requirements out of the published tiers entirely.

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

Answered from the vendors’ own pages

Cesium ion: How is Cesium ion priced?

By several meters at once: storage in gigabytes, streaming in gigabytes per month, and reality modelling in gigapixels per month. Commercial starts at $149 a month for an individual.

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.

Cesium ion: Is the free tier usable commercially?

No. Community is for non-commercial or open use. Commercial work needs a paid plan.

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.

Cesium ion: Can I run ion on my own infrastructure?

Only under a custom enterprise agreement negotiated with Cesium.

Foursquare Spatial Studio: What does it cost?

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

Cesium ion: Do I need Cesium ion to use CesiumJS?

No. CesiumJS is open source and free. ion provides hosted tiling, base layers and streaming that you would otherwise have to build.

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.
