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

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.
