## What it is
Leaflet-Geoman is a Leaflet plugin for drawing and editing geometry layers on interactive maps, supporting markers, polylines, polygons, circles, rectangles, GeoJSON, and more. It provides modes for drawing, editing, dragging, cutting, splitting, rotating, scaling, measuring, snapping, and pinning layers, with a free open-source core and paid Pro features.

## Use cases
- draw polygons on a leaflet map
- let users edit map shapes and vertices
- cut or split polygons on a map
- add snapping and measuring to map drawing
- import and edit GeoJSON layers on a map
- build a GIS annotation tool in the browser

## When to choose
- you use Leaflet and need geometry drawing/editing out of the box
- you want snapping, rotation, cutting, and splitting without building it yourself
- you need broad layer type support including GeoJSON and MultiPolygons

## When to avoid
- you need Pro features like auto-tracing or union/difference modes without a paid license
- you are not using Leaflet, MapLibre, or Mapbox GL JS
- you need server-side geometry processing rather than in-browser editing
