Where each one falls short

Nautilus Labs

  • Limited to maritime shipping industry use case, not applicable for other transportation sectors
  • Requires integration with vessel data collection systems for full functionality

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
