GRASS GIS in the browser

Run any GRASS module through a web form without installing anything locally. Results stream back in real time to a built-in terminal and 3-D map viewer.

Interactive map tools

Draw elevation profiles, compute histograms, set computational regions, and identify raster/vector values — all with point-and-click tools on a CesiumJS globe.

Session persistence

Autosave keeps your camera, layers, and tool state across page reloads. Named workspaces let you save, share, and restore complete analysis sessions across devices.
