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

Visual Crossing Weather

  • Sub hourly weather history, solar and wind energy elements, soil and evapotranspiration data and degree day calculations are excluded from the Professional plan
  • Removing the attribution requirement needs the Corporate plan or above
  • Usage is metered in records rather than API calls, and the metered plan requires a cost calculator to work out the bill
  • Per record rates are not stated on the editions page
  • Enterprise terms are custom rather than published
