GeoLibre
Free, open-source GIS from the opengeos project that loads, styles and analyses geospatial data in a web browser, as a desktop or phone app, or inside a Jupyter notebook, keeping the data on the user's own machine.

GeoLibre is a free, open-source GIS from the opengeos project, with Q. Wu as its author in the citation it asks for. The same workspace runs in a web browser, as a native desktop app on Windows, macOS and Linux, as Android and iOS apps, and inside Jupyter notebooks through a Python package; there is also an R package. It is built on MapLibre GL JS, deck.gl, DuckDB-WASM Spatial, Tauri, React and TypeScript. One project can be drawn by any of four rendering engines: MapLibre GL JS by default, Mapbox GL JS, CesiumJS or the ArcGIS Maps SDK, and the engines can be mixed in synchronised split panes.
It is a general tool for loading, styling and analysing place data. Layers come from local files or from web services (XYZ, WMS, WFS, WMTS, ArcGIS, STAC), cloud-native formats (GeoParquet, FlatGeobuf, PMTiles, Zarr, COG), 3D Tiles, LiDAR, Gaussian splats and DuckDB or PostgreSQL databases. A toolbox of more than a thousand geoprocessing tools for vector, raster, remote sensing, hydrology, terrain, LiDAR, network and projection work runs in the browser on WebAssembly, so no server is involved and data stays on the user's machine. There is a SQL workspace for DuckDB Spatial, a time slider, a story-map builder, field collection by GPS, multi-user collaboration, and sharing or embedding of projects. The maker's demos include Manhattan building footprints extruded by construction year with the subway on top, and basemaps of the Moon, Mars and other bodies; a gallery lists 105 projects built from public open data on themes such as natural hazards, climate, water, transport and cities.
It is released under the MIT licence at no cost. The web version runs without installing anything; installers and app-store builds cover desktop and mobile. The maker describes the project as stable and in active development with regular releases, says it is free and will stay so, and asks for sponsorship.
In this wiki's stack it is presentation: a place to look at and work on the data behind a model of a place, drawing on /presentation/maplibre/, /presentation/deck-gl/ and /presentation/cesiumjs/ underneath.
