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, native Android and iOS apps, in any modern web browser, and adapts responsively to mobile and small screens.

One project can be viewed through four rendering engines: MapLibre GL JS (the default), Mapbox GL JS, CesiumJS, or the ArcGIS Maps SDK for JavaScript. Switch the primary map from View → Rendering engine, or mix engines in synchronized split panes, without duplicating the project or its layers. See the rendering-engine guide for capabilities, credentials, and current compatibility.
