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.; onX Maps hunt, Offroad and Backcountry are entirely separate subscriptions, so a user needing more than one activity pays for more than one product with no combined bundle discount.
  • They diverge on capability: Cesium ion covers 3D Tiles tiling, onX Maps covers Land ownership boundaries.
  • 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.

onX Maps

  • Hunt, Offroad and Backcountry are entirely separate subscriptions, so a user needing more than one activity pays for more than one product with no combined bundle discount.
  • Elite-tier pricing at roughly $99.99 a year per product is expensive if a buyer only occasionally needs the private land ownership data it adds.
  • The apps are US and Canada focused, with more limited usefulness for international travel compared to a global mapping product.
  • Land ownership data, while extensive, can lag real-world changes in property boundaries in fast-changing areas.
  • It is not a general-purpose hiking or trail-review app in the way AllTrails or Gaia GPS are, so casual hikers without a land-boundary need may find the focus narrower than expected.
