The short version

  • Only Emlid Studio has a free tier, so it costs nothing to try first.
  • Each has a real cost: Emlid Studio it is free but it is not open source, so if Emlid changes direction or ends the product there is no community fork and no way to keep it maintained; 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: Emlid Studio covers RINEX conversion, Foursquare Spatial Studio covers Browser rendering at scale.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

Where each one falls short

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

Emlid Studio

  • It is free but it is not open source, so if Emlid changes direction or ends the product there is no community fork and no way to keep it maintained
  • Support is a community forum with no service level, which is a problem for a commercial survey firm that needs an answer before a deliverable deadline rather than when someone volunteers one
  • It only post-processes; there is no network adjustment, no project management, no least squares reporting suitable as a survey record, so it does not replace an office suite
  • The software exists to sell Emlid receivers, so features that matter to owners of competing hardware are unlikely to be prioritised even though third party RINEX is accepted
  • Results depend on the quality of the base data and on the user understanding fix, float and single solutions, and the interface will happily produce a poor solution without stopping an inexperienced operator

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

Emlid Studio: Is Emlid Studio really free?

Yes, with no seat limit and no paid tier. Emlid makes its money on GNSS receivers.

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.

Emlid Studio: Does it work with receivers from other manufacturers?

Yes. It accepts standard RINEX logs, so a base or rover from another brand can be processed.

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.

Emlid Studio: Is it open source?

No. It is free of charge but proprietary, so there is no community fork if the product is discontinued.

Foursquare Spatial Studio: What does it cost?

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

Emlid Studio: Can I use it as my survey office software?

No. It handles post-processing only. Network adjustment, drafting and deliverable production need other tools.

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.
