A Leaflet plugin that provides animated marker clustering for interactive maps, grouping large numbers of markers into clusters for performance and readability. It supports bulk marker operations, customizable cluster icons, spiderfy layouts, and cluster events.

Use cases

  • display thousands of map markers without performance issues
  • cluster map markers with zoom animations
  • customize cluster icon appearance on a Leaflet map
  • spiderfy overlapping markers on click
  • bulk add and remove markers on a map efficiently

When to choose

  • you use Leaflet and need to render many markers performantly
  • you want animated, customizable marker clustering out of the box
  • you need spiderfying and cluster event handling

When to avoid

  • you use a mapping library other than Leaflet
  • you only have a handful of markers and don't need clustering
  • you need a maintained plugin with frequent updates
