The short version

  • Only CesiumJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: CesiumJS the free Community tier does not permit commercial use; exactEarth exactEarth's own homepage, as captured by the Internet Archive on 28 December 2021, carried a banner stating: 'We are happy to announce that exactEarth is now part of Spire Global,' confirming in the vendor's own words that exactEarth was absorbed into Spire (now sold as Kpler's spireMT product); no independent exactEarth pricing survives
  • They diverge on capability: CesiumJS covers Core Functionality, exactEarth covers Satellite AIS data.
