The short version

  • Only CesiumJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: CesiumJS the free Community tier does not permit commercial 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
  • They diverge on capability: CesiumJS covers Core Functionality, 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.

CesiumJS

  • Streaming 3D terrain, imagery and building data into web applicationsnot Foursquare Spatial Studio
  • Tiling and hosting large geospatial and reality capture datasetsnot Foursquare Spatial Studio

Foursquare Spatial Studio

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

Where each one falls short

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

CesiumJS

  • The free Community tier does not permit commercial use
  • The cheapest commercial plan is $149 a month for an individual and $524 for a team
  • Team accounts are capped at 5 members on both the Commercial and Premium plans
  • Three separate quotas apply at once, being storage, monthly streaming and monthly reality modelling gigapixels, and exceeding any one of them constrains the account
  • Streaming is capped at 15 GB a month on the free tier

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

CesiumJS: Is Cesium ion free for commercial use?

Cesium offers a free Cesium ion community account, but the page does not explicitly state whether the free tier is permitted for commercial use or if restrictions apply to business applications.

Source
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.

CesiumJS: What are the limits of the free Cesium ion community account?

The page only mentions that a free community account is available but does not disclose usage limits, storage quotas, or feature restrictions for the free tier.

Source
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.

CesiumJS: What do paid Cesium ion tiers cost?

The page does not provide specific pricing for paid tiers. It directs users to sign up for a free community account or contact Cesium directly for detailed pricing information.

Source
Foursquare Spatial Studio: What does it cost?

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

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.
