GeoLibre launches as a lightweight, cloud‑native GIS platform that runs the same workspace on desktop and web. Built with Tauri, React, TypeScript and MapLibre GL JS, it delivers responsive maps on mobile, supports OpenFreeMap basemaps, and offers on‑map tools such as Measure, Bookmark and Minimap. The app stores projects in a .geolibre.json file for easy sharing.

Users can load vector and raster sources from local files or remote services—including XYZ tiles, WMS, WFS, ArcGIS, STAC, GeoParquet and PMTiles—then style layers with data‑driven symbology. Built‑in plugins expose LiDAR, 3D Tiles and Overture Maps, while a marketplace lets developers add external extensions. An in‑browser DuckDB‑Spatial SQL console queries loaded layers, streaming remote data via HTTP range requests.

GeoLibre’s Conversion menu transforms data to cloud‑native formats such as GeoParquet, FlatGeobuf and COG, and the Whitebox toolbox runs batch geoprocessing in the optional Python sidecar. Vector operations use Turf.js with a GeoPandas fallback; raster tools rely on rasterio. The platform embeds in Jupyter notebooks via a Python package, and a fully client‑side demo lives on GitHub Pages, confirming the 1.0 release as a stable prototype.
