A lightweight, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data. It runs in the web browser, on the desktop, on mobile, and inside Jupyter notebooks.

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.

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 started — install, run from source, and configure
• Features — the complete feature list

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.

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.

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.
