Leaflet is the leading open-source JavaScript library for building lightweight, mobile-friendly interactive maps, weighing about 40 kB gzipped. It provides tile layers, markers, popups, vector overlays, and GeoJSON support with a simple, well-documented API and a large plugin ecosystem.

Use cases

embed an interactive map in a web page
display markers and popups on a map
render GeoJSON data on a map
build a mobile-friendly map with pinch-zoom
overlay OpenStreetMap or WMS tile layers
visualize geographic points and polygons in a web app

When to choose

you need a lightweight, fast interactive map library for web or mobile browsers
you want broad plugin support and mature documentation
you need to work with OpenStreetMap tiles or GeoJSON out of the box

When to avoid

you need advanced 3D globe rendering or heavy geospatial analysis
you need a full GIS desktop application
you require server-side map rendering rather than client-side
