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.; Radar no free tier available
  • They diverge on capability: Cesium ion covers 3D Tiles tiling, Radar covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

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.

Radar

  • No free tier available
  • Annual contracts required with committed monthly quotas
  • Volume discounts applied manually; no public discount tiers
