Where each one falls short

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

Spire Global Maritime

  • Now part of Kpler rather than Spire, and spire.com/maritime redirects into the Kpler site
  • Pricing is not published
  • Sold as a data feed to be consumed through APIs, Snowflake, NMEA streams or FTP, so it needs engineering work before it is useful

VesselFinder

  • API access is billed in credits, and a satellite AIS position costs 10 credits against 1 for a terrestrial position
  • Credits expire 12 months after purchase
  • Credit packs start at 330 EUR for 10,000 credits, excluding VAT
  • Tracking a vessel outside terrestrial AIS range multiplies the cost of every position tenfold, so open ocean coverage is the expensive case rather than the standard one
