Where each one falls short

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

deck.gl

  • Open source framework with no commercial support tier available; support relies on community and GitHub issues
  • Maintained by community contributors (vis.gl contributors), not by a dedicated company support team

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

Can I use deck.gl for free?
Both have a free tier, so you can try either at no cost before committing.
What is deck.gl best used for?
deck.gl is most often used for gpu-accelerated visualisation of large geospatial datasets in the browser, composing map overlays from reusable layers, adding data layers on top of google maps or mapbox basemaps, high-precision plotting using 64-bit gpu computation. Of those, gpu-accelerated visualisation of large geospatial datasets in the browser and composing map overlays from reusable layers are not what Leaflet is typically brought in for.
