  • Performance with Large Data Sets
    Rendering large data sets (such as many markers or complex geometries) can impact performance.
  • Steeper Learning Curve for Advanced Customization
    While basic use is straightforward, more advanced customizations can be challenging and may require deeper knowledge of JavaScript and Leaflet's architecture.
  • Limited 3D Support
    Leaflet is primarily designed for 2D maps, and doesn't natively support 3D visualizations, which may be a limitation for some applications.

  • Reliance on Internet Access
    Users need an active internet connection to utilize the tool, which can be a limitation in areas with unreliable internet service.
