The short version

  • Only StormGlass has a free tier, so it costs nothing to try first.
  • Each has a real cost: Sea Machines requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase; StormGlass the free tier allows 10 API requests per day and is not licensed for commercial use
  • They diverge on capability: Sea Machines covers Autonomous control, StormGlass covers Marine weather data.

Where each one falls short

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

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

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
