Choosing among Leaflet, OpenLayers, Mapbox, Cesium, ArcGIS, deck.gl, and Google can feel overwhelming. This quick guide highlights where each library shines so geospatial specialists can match tools to use cases—without deep-diving seven doc sites first.
Quick definitions
Leaflet — Lightweight 2D web maps; huge plugin ecosystem.
OpenLayers — Powerful 2D engine with projections, formats, and controls.
Mapbox GL JS — Modern WebGL 2D/“3D extrusions,” style-spec, hosted services. Docs
CesiumJS — High-performance true 3D globe/tileset rendering.
ArcGIS Maps SDK for JavaScript — Enterprise GIS with rich analysis widgets.
deck.gl — WebGL layers for large datasets; often used atop MapLibre/Mapbox.
Google Maps JS API — Familiar basemap + places/services.
One-screen decision table
Library | Best for | 2D/3D | License & model | Notes |
Leaflet | Simple web maps, fast MVPs | 2D | Open-source | Small bundle, many plugins |
OpenLayers | Complex 2D GIS features | 2D | Open-source | Strong projections & formats |
Mapbox GL JS | Styled vector maps, mobile parity | 2D/3D extrusions | Commercial plans | Tight style spec & studio |
CesiumJS | True 3D globe, terrain, 3D tiles | 3D | Open-source + commercial options | Photorealistic 3D tiles |
ArcGIS JS | Enterprise apps, analysis widgets | 2D/3D | Commercial | Deep ArcGIS integration |
deck.gl | Big-data visualization layers | 2D/3D | Open-source | Pairs with MapLibre/Mapbox |
Google Maps | Consumer UX, local search, places | 2D/3D | Commercial | Global POIs & routing |

How to choose a mapping library (Leaflet, OpenLayers, Mapbox, Cesium, ArcGIS, deck.gl, Google)
Need quick 2D maps with minimal code? Start with Leaflet.
Complex projections or custom formats? Try OpenLayers.
Brandable vector styles & mobile parity? Choose Mapbox GL JS.
Immersive globe or city-scale 3D? Go CesiumJS.
Enterprise GIS & analysis widgets? Use ArcGIS.
Massive points/paths with GPU layers? Add deck.gl.
Consumer UX & places services?Google Maps fits.
FAQ
Is there a single “best” library?
No—pick based on data, rendering needs, licensing, and team skills (Unknown metrics vary by project).
Can I mix libraries?
Yes. For example, use MapLibre/Mapbox for basemap and deck.gl for GPU layers.
Which options are open-source?
Leaflet, OpenLayers, deck.gl, and CesiumJS maintain open-source cores; Mapbox, Google, and ArcGIS offer commercial terms—see vendor docs for details.
What about 3D in Leaflet/OpenLayers?
They are primarily 2D; you can simulate depth, but for true 3D globes/tilesets, CesiumJS or ArcGIS 3D are purpose-built.
Key takeaways
Align library choice to use case first, not brand.
Consider licensing & services early.
You can mix tools: basemap engine + visualization layers.
