GeoLibre

A free and open-source, lightweight, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data. It runs everywhere you do, in the web browser, on the desktop, on mobile, and inside Jupyter notebooks, all while keeping your data local and private.

It also ships 1,000+ geoprocessing tools that run entirely in your browser on WebAssembly — terrain, hydrology, LiDAR, remote sensing, and vector analysis with no server, no install, and no data ever leaving your machine.

GeoLibre is built with Tauri v2, React, TypeScript, MapLibre GL JS, DuckDB-WASM Spatial, and deck.gl. The same workspace runs as a native desktop app, a native Android app, in any modern web browser, and adapts responsively to mobile and small screens.

• Launch GeoLibre Web — the full app in your browser, nothing to install
• Download the desktop app — Windows, macOS, and Linux installers
• Get it on the Mac App Store — the sandboxed macOS build
• Get it on Google Play — the native Android app
• 1,000+ geoprocessing tools — the full toolbox, in the browser
• Get started — install, run from source, and configure
• Features — the complete feature list

NYC buildings and subways

Manhattan building footprints extruded in 3D and colored by construction era, with the MTA subway lines and stations on top and a legend generated automatically from the layers' symbology.

The animation below runs the Time Slider along the buildings' construction year, from 1850 to 2025, so Manhattan fills in era by era. Click it to play the full-quality video.

Planetary basemaps

GeoLibre is not limited to Earth. Planetary basemaps from OpenPlanetaryMap and USGS Astrogeology cover the Moon, Mars, Mercury, Venus, the Galilean moons (Io, Europa, Ganymede, Callisto), Titan, Pluto, and Charon, with a per-project ellipsoid so distance, area, and scale measurements match the body you are mapping. The deep-space starfield behind each globe comes from the Atmosphere Effects plugin.

Earth	Moon	Mars
Mercury	Pluto	Venus
Europa	Callisto	Charon

Switch bodies from the planet switcher in the Layers panel. See Demos for more.

Geoprocessing: 1,000+ tools, zero install

Processing → Whitebox opens a toolbox of 1,000+ geoprocessing tools that execute in the browser through a WebAssembly runtime with native raster and vector I/O. There is no Python sidecar to install and no server to call — the tools, your data, and the results all stay on your machine, so the full toolbox is available on GeoLibre Web, on the desktop app, and on Android alike.

The tools come from the Whitebox Next Gen suite plus GeoLibre's own WASM tools, and are browsable by category straight from the Processing menu:

Category	Tools	Examples
Vector	280	overlays, buffers, joins, cleaning, topology, generalization
Raster	232	algebra, filters, reclassification, zonal and focal statistics
Remote sensing	154	spectral indices, band math, classification, change detection
Hydrology	100	flow accumulation, watersheds, stream networks, depression filling
Terrain	99	slope, aspect, hillshade, curvature, ruggedness, viewsheds
LiDAR	65	point-cloud filtering, ground classification, DEM/DSM generation
Conversion	49	format translation to cloud-native GeoParquet, PMTiles, and COG
Network	26	connectivity, cost distance, and routing analysis
Projection	4	reprojection for raster and vector data

Any tool is deep-linkable with a ?tool= URL parameter that preselects it and pre-fills its form. See the Processing Tools guide for details, and Geoprocessing in the Browser for a video walkthrough.

Acknowledgements

GeoLibre is built on the free and open-source geospatial and web communities — including MapLibre GL JS, deck.gl, DuckDB-WASM Spatial, Turf.js, Tauri, React, and many more. See the full Acknowledgements page for the complete list of projects and community contributors.

• The Atmosphere Effects plugin (deep-space backdrop, parallax starfield, comets, and the globe atmosphere halo) adapts the technique and visual design from Leonel Dias's article Globe atmosphere, halo, and comets — the layered Canvas 2D approach, the halo gradient and "screen" blend, the limb-sampling that keeps the halo aligned under pitch, and the starfield/comet parameters.
• Community contributors — thanks to Ryanphoenix for many valued contributions, including issue reports, feedback, and improvements.
• Beta testers — thanks to René van der Velde (Netherlands) for early testing, detailed bug reports, and feature requests.
