QGIS
QGIS is a free and open source GIS application that can be used for viewing, editing and analysing geospatial data. QGIS supports a very wide range of vector and raster formats and also common API protocols like WMS, WMTS, WCS and WFS.
In supercomputers, QGIS could be used for example to visualize the resulting files from processing with other tools: lastools, R, Python etc.
Available
QGIS is available with following versions:

SagaGIS toolbox in QGIS
SagaGIS tools are not available by default with QGIS 3.31 in Processing Toolbox, but can be added with installing Saga Next Gen
