The short version

  • 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.; SW Maps android only. There is no iOS version and no sign of one, which rules it out for organisations that issue iPhones and iPads to field staff.
  • They diverge on capability: Cesium ion covers 3D Tiles tiling, SW Maps covers Custom feature layers.
  • 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 SW Maps
  • A simulation team streaming global terrain and imagery into an Unreal Engine environmentnot SW Maps
  • An urban planning department publishing a city model that planners can inspect without desktop GIS softwarenot SW Maps
  • A software product embedding 3D geospatial views and needing hosted tiling rather than building a tilernot SW Maps

SW Maps

  • An NGO or municipal utility mapping water points, pipe networks or road assets on a budget that cannot absorb per-user GIS subscriptionsnot Cesium ion
  • A survey team pairing a low-cost RTK receiver with Android tablets to collect centimetre-accurate attributed features without buying field software seatsnot Cesium ion
  • A university field course teaching GNSS data collection where every student needs the tool on their own devicenot Cesium ion
  • A consultant doing a one-off asset inventory who needs shapefile or GeoPackage output and does not want to start an annual subscription for a three-week jobnot 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.

SW Maps

  • Android only. There is no iOS version and no sign of one, which rules it out for organisations that issue iPhones and iPads to field staff.
  • There is no back end: no user management, no central project sync, no audit trail. Data lives on the device until someone exports it, and a lost tablet is lost data.
  • No commercial support contract exists, so an organisation with a compliance requirement for vendor support cannot use it for regulated work regardless of technical fit.
  • It is maintained by a small consultancy as a side product of its own project work, so the roadmap follows Softwel’s needs and a feature you depend on may never be prioritised.
  • Form logic is basic compared with dedicated survey platforms: no meaningful skip logic, validation or multi-user assignment, so complex questionnaires quickly outgrow it.

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.

SW Maps: Is SW Maps really free?

Yes. It is free with no advertising and no paid tier. There is no subscription and no feature paywall.

Cesium ion: Is the free tier usable commercially?

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

SW Maps: Does it support RTK receivers?

Yes, over Bluetooth or USB serial, with NTRIP correction support, antenna height and per-point fix quality recording.

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

Only under a custom enterprise agreement negotiated with Cesium.

SW Maps: Is there an iOS version?

No. Android only.

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.

SW Maps: Who maintains it?

Softwel, an engineering consultancy in Kathmandu, Nepal, which built it for its own infrastructure projects.

SW Maps: Can we get support?

Not contractually. There is no commercial support agreement, which is the main reason organisations with compliance obligations choose a paid alternative.
