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

MarineTraffic

  • Specific numeric prices for the Basic/Essential tiers are not published on a directly accessible page (plans pages are bot-protected)
  • Enterprise tier is sales-assisted, quote-only
  • API access is credit-consumption based with cost varying by AIS data source and detail level, making cost opaque
  • Commercial API access now routes through parent company Kpler via demo request
