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

Vizion

  • No price is published: the site names a pricing link but shows no per container rate, no plan tier and no minimum, and every route leads to a demo or a sales conversation
  • There is no self service signup, so even a small shipper must go through sales to start tracking
  • Container tracking, trade intelligence and supply chain optimisation are separate product lines rather than one subscription
