Cloud-native GIS platform

A lightweight, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data.

GeoLibre is built with Tauri, React, TypeScript, MapLibre GL JS,<br>DuckDB-WASM Spatial, and deck.gl. The same workspace runs across desktop<br>and web environments, adapting responsively to mobile screens, with fast<br>local and cloud-native data work, project files, styling, plugins, and<br>modern geospatial workflows.

What GeoLibre does today&para;

MapLibre map workspace&para;

Pan, zoom, rotate, and tilt a MapLibre map with OpenFreeMap basemaps or a blank background. Toggle built-in controls for navigation, globe, terrain, geolocation, scale, attribution, and logo, plus on-map tools like Measure, Bookmark, Minimap, and View State.

Local and remote data&para;

Load local and remote vector and raster data, inspect attributes in the table, style layers with data-driven symbology, reorder and refresh layers, and save, reopen, or share .geolibre.json projects.

Plugins and marketplace&para;

Activate built-in plugins for layer control, basemaps, MapLibre components, swipe, street view, time slider, Overture Maps, LiDAR, GeoAgent, and GeoEditor, and install, update, or remove external plugins from the built-in marketplace.

Advanced layer formats&para;

Add Data covers XYZ, WMS, WFS, WMTS, ArcGIS, and STAC services; GeoParquet, FlatGeobuf, PMTiles, and Zarr cloud formats; COG and GeoTIFF rasters and MBTiles; LiDAR, Gaussian splats, and 3D Tiles; and DuckDB and PostgreSQL databases.

Conversion and Whitebox&para;

Convert data to cloud-native GeoParquet, FlatGeobuf, PMTiles, and COG from the Conversion menu, and run batch geoprocessing with the Whitebox toolbox on the optional Python sidecar.

SQL Workspace&para;

Run DuckDB Spatial SQL in the browser against loaded layers, local files, and remote URLs. Auto-wraps bare URLs into the matching reader and streams remote files over HTTP range requests. Includes sample queries, query history, and adding a result (with an optional layer name) to the map or exporting it as CSV or GeoParquet.

Vector tools&para;

Common geometry tools under Processing → Vector: buffer, centroids, convex hull, dissolve, bounding box, simplify, clip, intersection, difference, and union. They run in the browser with Turf.js, with an optional GeoPandas sidecar engine for every tool.

Raster tools&para;

Common raster tools under Processing → Raster: hillshade, slope, aspect, reproject, resample, clip by extent, clip by mask layer, polygonize, and contour. They run on a rasterio Python sidecar with a file path in and a file path out. Drag a GeoTIFF/COG onto the map to add it as a raster layer.

Python and Jupyter&para;

Embed the full GeoLibre app in a Jupyter notebook with the geolibre Python package. A leafmap-style API (add_geojson, add_tile_layer, add_cog) drives the map, and the project syncs both ways so UI edits are readable back from Python.

Learn GeoLibre&para;

New to GeoLibre? Start with the User Guide for a feature-by-feature tour of the workspace, menus, panels, and tools, then follow the Tutorials for hands-on, end-to-end workflows.

Interface Overview: the toolbar, panels, map, and status bar.

Adding Data: every file, web service, cloud, 3D, and database source.

Processing Tools and SQL Workspace: analysis with vector, raster, conversion, Whitebox, and DuckDB Spatial SQL.

Plugins & Marketplace: activate built-ins and install from the registry.

Your First Map: add a layer, style it, inspect it, and share it.

Try it in the browser&para;

The live demo is the browser-capable version of the GeoLibre desktop UI. It is useful for exploring the map, loading browser-selected vector data supported by DuckDB-WASM Spatial, adding URL-based layers, styling layers, and testing plugins. Desktop-only file dialogs, local MBTiles, local raster reads, and filesystem save/open operations still require the installed Tauri app.

Hosted on GitHub Pages, private by design

The live demo is a static site deployed on GitHub Pages and runs entirely in your browser. It has no analytics and no server account, and the data you load is processed client-side in your browser session. Data leaves your browser only when you choose to add a remote URL or explicitly share a project.

Open a project by passing a public .geolibre.json URL with the url query parameter:

https://viewer.geolibre.app/?url=https://share.geolibre.app/giswqs/3d-tiles.geolibre.json

For narrow embeds, add ?layout=compact to the demo URL to use icon-only toolbar buttons and hide project...
