  • They diverge on capability: Kepler.gl covers Core Functionality, 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.

Kepler.gl

  • Kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.

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.
