Where each one falls short

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

Kpler

  • No self-serve signup; access requires requesting a demo or contacting sales
  • No pricing published at any tier on the vendor site
  • Product is split across separately branded terminals (Commodity Terminal, Financial Flows, MarineTraffic), implying separate logins/contracts

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
