CanvasGlobe vs Cobe
CanvasGlobe and Cobe can both produce an interactive globe, but they optimize for different jobs. Cobe is a compact WebGL globe focused on a polished visual with markers and arcs. CanvasGlobe is a larger Canvas 2D visualization toolkit that also provides flat maps, country data, choropleths, CSV input, interaction, and export workflows.
| Requirement | CanvasGlobe | Cobe |
|---|---|---|
| Renderer | Canvas 2D | WebGL |
| Runtime dependencies | Zero | Zero |
| Main goal | Data-rich globe and flat-map components | Very small decorative WebGL globe |
| Flat map projections | Included | Not its product focus |
| Country choropleths | Included | Not its product focus |
| Markers and arcs | Included | Included |
| CSS-anchor labels | No dedicated API | Included for bindable markers and arcs |
| CSV helpers | Included | Bring your own transformation |
| PNG and WebM workflows | Included | Use browser canvas/WebGL capture yourself |
| GIS, terrain, street maps | No | No |
Choose Cobe when
- minimum globe bundle size is the main requirement;
- WebGL is available and appropriate;
- the globe is primarily decorative;
- you want Cobe's bindable marker and arc anchors; or
- flat maps and country-level data tools are unnecessary.
Choose CanvasGlobe when
- WebGL cannot be assumed or is intentionally avoided;
- the same data must work on a globe and flat world map;
- choropleths, country interaction, CSV input, or built-in export matter;
- keyboard controls and reduced-motion behavior are requirements; or
- a self-contained Canvas 2D rendering path is preferable.
Neither library is a terrain or tiled-map engine. Evaluate MapLibre or Cesium for those requirements.
Test before choosing
Measure both libraries with the real marker count, target devices, and bundler. Check visual quality, CPU/GPU use, reduced-motion behavior, and the complete application bundle rather than comparing a headline size alone.
