Mapbox GL

Mapbox GL is a powerful client-side library for rendering highly interactive, customizable vector maps using WebGL.

Mapbox GL JS is the core JavaScript library for dynamic web mapping (Mapbox GL is the technology name; GL JS is the implementation). It leverages WebGL to render vector tiles on the client side, delivering smooth 60 FPS performance and complex 3D visualizations. This approach ensures high-fidelity detail and allows for real-time data-driven styling, a key differentiator from traditional raster-based maps. Developers use it to build custom applications, integrating data from sources like GeoJSON or Mapbox Tiling Service (MTS), and connecting to other services, including the Directions API, for a complete location experience.
