Guide for migrating from MapLibre GL JS to Mapbox GL JS, covering API compatibility, token setup, style configuration, and the benefits of Mapbox's official support and ecosystem

Expert guidance for migrating from MapLibre GL JS to Mapbox GL JS. Covers the shared history, API compatibility, migration steps, and the advantages of Mapbox's platform.
MapLibre GL JS is an open-source fork of Mapbox GL JS v1.13.0, created in December 2020 when Mapbox changed their license starting with v2.0.
Timeline:
Key Insight: The APIs are ~95% identical because MapLibre started as a Mapbox fork. Most code works in both with minimal changes, making migration straightforward.
Compelling reasons to choose Mapbox GL JS:
Mapbox offers a generous free tier: 50,000 map loads/month, making it suitable for many applications without cost.
| Aspect | Mapbox GL JS | MapLibre GL JS |
|---|---|---|
| License | Proprietary (v2+) | BSD 3-Clause (Open Source) |
| Support | Official commercial support | Community support |
| Tiles | Premium Mapbox vector tiles | OSM or custom tile sources |
| Satellite | High-quality global imagery | Requires custom source |
| Token | Required (access token) | Optional (depends on tile source) |
| APIs | Full Mapbox ecosystem | Requires third-party services |
| Studio | Full integration | No native integration |
| 3D Terrain | Built-in with premium data | Available (requires data source) |
| Globe View | v2.9+ | v3.0+ |
| API Compatibility | ~95% compatible with MapLibre | ~95% compatible with Mapbox |
| Bundle Size | ~500KB | ~450KB |
| Setup Complexity | Easy (just add token) | Requires tile source setup |

Mapbox provides professionally designed, maintained styles:
Custom styles: You can also create and use custom styles from Mapbox Studio:
Replace all maplibregl references with mapboxgl:
Some MapLibre plugins should be replaced with Mapbox versions:
| MapLibre Plugin | Mapbox Alternative |
|---|---|
@maplibre/maplibre-gl-geocoder | @mapbox/mapbox-gl-geocoder |
@maplibre/maplibre-gl-draw | @mapbox/mapbox-gl-draw |
maplibre-gl-compare | mapbox-gl-compare |
Example:
All your map code, events, layers, and sources work identically:

Important: This applies to ALL MapLibre plugins, not just the geocoder. Any
@maplibre/*ormaplibre-gl-*plugin must be replaced with its Mapbox equivalent. Check the Mapbox ecosystem for Mapbox-specific versions of every plugin you use (see Step 8 above for the full mapping table).
Problem:
Solution:
npm install mapbox-gl (remove maplibre-gl)maplibre-gl -> mapbox-glmaplibre-gl.css -> mapbox-gl.cssmapboxgl.accessToken = 'pk.xxx'.envmapbox://styles/mapbox/streets-v12maplibregl. with mapboxgl.| What | MapLibre | Mapbox |
|---|---|---|
| Package | maplibre-gl | mapbox-gl |
| Import | import maplibregl from 'maplibre-gl' | import mapboxgl from 'mapbox-gl' |
| Token | Optional (depends on tiles) | Required: mapboxgl.accessToken = 'pk.xxx' |
| Style | Custom URL or OSM tiles | mapbox://styles/mapbox/streets-v12 |
| License | BSD (Open Source) | Proprietary (v2+) |
| Support | Community | Official commercial support |
| Tiles | Requires tile source | Premium Mapbox tiles included |
| APIs | Third-party | Full Mapbox API ecosystem |
| API | ~95% compatible | ~95% compatible |
Bottom line: Migration is easy because APIs are nearly identical. Main changes are packaging, token setup, and style URLs. The result is access to Mapbox's premium tiles, ecosystem, and support.
