Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MarineTraffic

  • Specific numeric prices for the Basic/Essential tiers are not published on a directly accessible page (plans pages are bot-protected)
  • Enterprise tier is sales-assisted, quote-only
  • API access is credit-consumption based with cost varying by AIS data source and detail level, making cost opaque
  • Commercial API access now routes through parent company Kpler via demo request

Sea Machines

  • Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
  • Pricing is not published and is arranged directly with the vendor
  • The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval
