Jeff Franzen · personal lab
Real GIS in a tab. Data stays local.
GeoLibre is Qiusheng Wu’s open-source cloud-native GIS — MapLibre GL JS, DuckDB-WASM Spatial, deck.gl, optional Cesium. Browser, desktop, mobile, Jupyter. No GIS server. Nothing leaves the machine unless you load a remote URL.
What it is
A full GIS workspace that runs where you already are.
Why it exists
Analysis without standing up a stack. Project file, not a login.
This site
Jeff’s lab and showcase. Not the official docs. Not Spatial Radar.
