Tangram is a JavaScript library for rendering 2D and 3D maps live in the browser using WebGL, tuned for OpenStreetMap but supporting GeoJSON/TopoJSON and other vector tile sources. It integrates as a Leaflet plugin and uses declarative scene files for data sources, layers, and styling.

Use cases

• render interactive 2D and 3D vector maps in the browser
• style custom map themes with a declarative scene file
• display OpenStreetMap vector tiles with WebGL acceleration
• add a WebGL map layer to an existing Leaflet map
• visualize GeoJSON or TopoJSON data as a map
• create creative cartography with custom raster and vector tile styling

When to choose

• you need GPU-accelerated 2D/3D map rendering in a web browser
• you want deep custom styling of vector tiles for creative cartography
• you already use Leaflet and want a WebGL-powered layer
• you need to render GeoJSON/TopoJSON or custom vector tile sources

When to avoid

• you need a native mobile map engine (use Tangram ES instead)
• you just need simple slippy maps without custom styling (plain Leaflet may suffice)
• you need a fully maintained project with active feature development
• your target browsers lack WebGL support
