  • Customized pricing model makes comparison difficult without direct vendor engagement

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
