Where each one falls short

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

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

Flexport

  • $5,000 monthly minimum fulfillment spend requirement excludes small and medium businesses
  • Inconsistent customer service with reports of slow quote responses that delayed orders by up to two months
  • Hidden fees and additional charges beyond quoted prices reported by multiple customers
  • Quote-only pricing model makes budgeting difficult compared to published rate cards from competitors
