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

OSRM

  • Free and open source routing engine under the 2-clause BSD license, no commercial tier
