The short version

  • Only Leaflet has a free tier, so it costs nothing to try first.
  • Each has a real cost: Leaflet 2D only with no support for 3D features, tilt, or rotation; Sea Machines requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • They diverge on capability: Leaflet covers Core Functionality, Sea Machines covers Autonomous control.

Where each one falls short

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

Leaflet

  • 2D only with no support for 3D features, tilt, or rotation
  • Performance degrades when rendering large datasets of complex vector geometries without optimization
  • Limited dynamic styling support; style is fixed on the server when using raster tiles
  • Lacks native support for WMS features; requires plugins like Leaflet.WMS and complex feature identification is cumbersome
  • Requires external tile service for map imagery; does not provide map tiles natively

Sea Machines

  • Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
  • Pricing is not published and is arranged directly with the vendor
  • The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval
