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

Windward

  • Requires embedded expert analysts for actionable intelligence; cannot operate fully autonomously
  • Platform focuses on specific maritime regions (Strait of Hormuz, Somali piracy zones); may not provide equally robust global coverage
  • Classified as unclassified and shareable, limiting penetration into highly classified defense operations
  • API-dependent architecture (GraphQL-based) may create integration complexity for some organizations
  • Multi-source data integration can be resource-intensive for organizations lacking dedicated intelligence staff
