A very fast JavaScript library for clustering large sets of geospatial points (GeoJSON features) for browsers and Node. It powers marker clustering in Mapbox GL JS and supports millions of points efficiently.

Use cases

• cluster map markers for millions of points
• show aggregated map pins at low zoom levels
• implement click-to-zoom on map clusters
• paginate points inside a map cluster
• generate vector tiles with clustered points
• cluster GeoJSON point data in Node

When to choose

• you need fast client-side or server-side clustering of large GeoJSON point datasets
• you use Leaflet, Mapbox GL JS, or MapLibre and need marker clustering
• you need cluster drill-down, expansion zoom, or tile output

When to avoid

• you need clustering of non-point geometries like lines or polygons
• you need heatmaps rather than discrete clusters
• your dataset is tiny and simple marker rendering suffices
