Everything you need to build map apps

🗺️

High-performance vector tiles

A flexible OpenGL vector-tile renderer with CartoCSS styling, MBTiles, PMTiles, GeoJSON and Mapbox Vector Tiles support.

📱

Truly cross-platform

One C++ core, native bindings for Android (Java/Kotlin), iOS and macOS via Mac Catalyst (Objective-C/Swift), the same core in WebAssembly for the web, plus a NativeScript plugin.

🧭

Routing & geocoding

Embedded Valhalla street routing, SGRE indoor routing, and offline forward/reverse geocoding.

📦

Offline first

MBTiles and PMTiles files, a persistent tile cache, bundled styles and offline routing and geocoding packages — a full map with no connection.

New in Massif Maps

Features shipping beyond the original CARTO SDK.

⛰️3D TerrainNew

Real 3D elevation with render-to-texture fill draping, correct depth occlusion and fast-zoom performance.

〰️On-the-fly ContoursNew

Generate contour lines directly from RGB elevation tiles — no pre-baked mbtiles — plus GPU shader contours.

🎚️

🎚️Composite Vector LayersNew

Weave external raster, hillshade and vector sources into a single CartoCSS style, ordered by layer name.

🌄Advanced HillshadeNew

Multiple hillshade algorithms (GDAL, Igor, multidirectional), exaggeration and custom raster shaders.

🌅Sky, Sun & ShadowsNew

One directional light and a shader sky shared by ground, terrain and fog — with a replaceable sky shader.

🌲3D ModelsNew

glTF models instanced at the points of any vector layer — trees, turbines, landmarks — lit, shadowed and fogged like the buildings.

🌙Objects in the SkyNew

Sun, moon, stars or an aircraft anchored by direction, plus a free-roam camera that can look above the horizon.

🖌️Post-processingNew

Full-screen fragment shaders with access to the terrain depth — the peak-finder relief look is one.

🏷️Shields & Font IconsNew

Names that take the free side of their icon, SDF icon glyphs, rounded plates and panorama callout labels.

🎨Live Style ParametersNew

Change a colour, a table or the selected feature and get a repaint instead of a re-decode of every tile.

📐GeoJSON Vector TilingNew

App data tiled through a geojson-vt pyramid and styled with CartoCSS — 3.3× faster on long lines.

➡️Maneuver ArrowsNew

Turn arrows cut from the route and drawn as a line with an arrow head — no marker, no bitmap.

🧱

🧱MapLibre TilesNew

Read MLT as well as MVT — same decoder, same CartoCSS, format taken from the source or detected per tile.

🧩

🧩PMTilesNew

Single-file tile pyramids (PMTiles v3), local or over HTTP, anywhere a TileDataSource is expected.
