Hire a Leaflet, Mapbox & MapLibre developer who knows the trade-offs
We build the map layer of your web app, from lightweight Leaflet maps to WebGL vector-tile maps with 3D terrain in MapLibre GL JS. Our focus is rendering performance, clean cartography and running costs that don't grow with every page view.
Leaflet vs Mapbox GL JS vs MapLibre GL JS, explained by developers who use all three
Leaflet is small, stable and BSD-licensed, ideal for raster basemaps and moderate GeoJSON overlays. Mapbox GL JS and MapLibre GL JS render vector tiles on the GPU with WebGL, so they handle millions of features, smooth rotation and pitch, and 3D terrain. OpenLayers remains the strongest choice when you need custom projections or heavy use of OGC services such as WMS, WFS and WMTS.
Licensing is where teams get surprised. Since version 2, Mapbox GL JS is distributed under a proprietary license, requires a Mapbox access token, and is billed per map load even if your tiles come from your own server. MapLibre GL JS is the community-maintained open-source fork of Mapbox GL JS v1, with a near-identical API, active development and no token. For many products, MapLibre plus self-hosted vector tiles is the cost-effective, lock-in-free option.
As a Leaflet, Mapbox & MapLibre developer team, Codeinspira handles library selection, style design, plugin integration, large-dataset performance and Mapbox-to-MapLibre migration. Our experience comes from production WebGIS work such as a national land geoportal for Indonesia's ATR/BPN and an EUDR traceability platform for PT Astra Agro Lestari Tbk, where maps had to stay responsive over country-scale polygon data.
What our web map developers deliver
Front-end mapping work, backed by tile servers and APIs when the data demands it.
Leaflet map development
Lightweight maps for store locators, asset registers and dashboards, using plugins such as MarkerCluster, Leaflet.draw and heatmap layers.
LeafletMapLibre GL JS vector maps
WebGL maps with vector tiles, custom style JSON, multilingual labels and 3D terrain, with no access token required.
MapLibre GL JSMapbox GL JS applications
Building and maintaining apps that deliberately use Mapbox services, including Mapbox Studio styles and map-load usage optimization.
Mapbox GL JSMapbox to MapLibre migration
Swapping the library, porting styles, sprites and fonts, and replacing Mapbox-hosted tiles with your own so the subscription can be cancelled.
Cost reductionLarge GeoJSON performance
Converting heavy GeoJSON into MBTiles or on-the-fly PostGIS vector tiles, with per-zoom simplification and trimmed attributes.
PerformanceOpenLayers OGC clients
Map clients for GeoServer WMS, WFS and WMTS, including non-Web-Mercator projections and time-enabled layers.
OpenLayersInteractive map features we build every week
Each feature is shaped around who uses the map: field staff, analysts or the public.
- Server- or client-side clustering for hundreds of thousands of points
- Custom basemap styles authored in Maputnik or Mapbox Studio
- 3D terrain, hillshading and extruded buildings
- Draw, edit, snap and measure points, lines and polygons
- Attribute filtering and data-driven styling in real time
- Heatmaps and choropleths with dynamic legends
- Swipe and side-by-side comparison of layers or imagery dates
- Live GPS and vehicle tracking over WebSocket or SSE
- Typed map components for React, Vue and Next.js
- Map snapshot export to PNG or PDF reports
Where teams hire a Leaflet or MapLibre developer
Typical projects that come to us for front-end map work.
SaaS products
Map features inside a product whose costs must stay flat as the user base grows.
Agriculture and plantations
Field, block and concession maps with fire hotspot overlays filterable by estate.
Government open-data portals
Public geoportals that publish large land-use or cadastral polygon layers.
Real estate and valuation
Property maps combining parcel geometry with valuation attributes and comparables.
Logistics and fleet
Live vehicle positions, routes and service zones on a single performant map.
NGOs and research
Story maps and monitoring dashboards that must run on modest hosting budgets.
Map developers who fix performance at the source
We own the whole path from raw geodata to pixels in the browser.
Full-stack geospatial skills
Our team also runs PostGIS and GeoServer, so slow maps are fixed in the tiling and query layer, not just patched in JavaScript. That usually means bigger and more durable speed gains.
Vendor-neutral advice
We resell no map platform or license. Whether we recommend Leaflet, Mapbox or MapLibre depends only on your requirements and long-term cost.
Proven on large datasets
National geoportals and EUDR compliance platforms demand stable maps over very large polygon layers. We apply the same tiling and styling patterns to your project.
