Where each one falls short

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

FleetMon

  • Service discontinued in January 2024 and fully phased out with transition to MarineTraffic
  • Free tier coverage was limited compared to premium plans requiring subscription fees
  • Data gaps in regions with poor terrestrial AIS infrastructure before satellite coverage was added

StormGlass

  • The free tier allows 10 API requests per day and is not licensed for commercial use
  • Commercial use and any support at all start at the Medium plan, 49 euros a month
  • The Small plan at 19 euros a month has no support and no commercial licence
  • Request allowances are daily rather than monthly, so a burst of traffic cannot borrow against a quiet week
