Overview

GeoLibre is a free, open-source, lightweight cloud-native GIS platform that runs in the web browser, as a native desktop app (Tauri v2), on Android, and inside Jupyter notebooks — all while keeping your data local and private. It’s built with React and TypeScript and integrates MapLibre GL JS, deck.gl, and DuckDB‑WASM Spatial to deliver interactive mapping, client-side spatial SQL, and high-performance visualizations.

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.

Launch the full app in your browser (https://web.geolibre.app/) or download native installers for Windows, macOS, and Linux; packages are available via Microsoft Store, Flatpak, AUR, PyPI and conda-forge.
SQL Workspace powered by DuckDB‑WASM Spatial and a Python package for Jupyter/Colab; the project highlights “Geoprocessing in the Browser: 700+ Free GIS Tools” for zero-install spatial analysis.
Rich demos include 3D Tiles, a Manhattan buildings + subway demo with an automatic legend and a Time Slider animation, and planetary basemaps (Moon, Mars, Mercury, Venus, Galilean moons, Pluto/Charon) with per-project ellipsoids and an Atmosphere Effects plugin (starfield, halo, comets).

GIS analysts, web mapping developers, data scientists using notebooks, educators, and planetary mapping researchers who need cross-platform deployment, client-side spatial SQL, and privacy-preserving, zero-install geoprocessing.

GeoLibre brings heavy geoprocessing and advanced visualization into the browser and native apps by combining Tauri v2 native builds, MapLibre + deck.gl rendering, and DuckDB‑WASM Spatial for client-side spatial SQL. It is trending now — gaining 420 stars today (2,722 total) — driven by the GeoLibre 1.0 demos and videos, the live web app and shareable projects, and the Jupyter/Colab examples that showcase powerful, zero-install spatial workflows.

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.

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.

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.

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

Full documentation, including the User Guide and Tutorials, is published at geolibre.app.

Reference

Contributions are welcome. See the Contributing guide for the development setup, repository layout, and quality gate.

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.
