What SAGA GIS is

SAGA GIS is a desktop geographic information system for processing and analyzing geodata. Modules are available through a graphical interface or scripting environments, including command-line tools and scripts in Python, Java, and R. Its library covers climate and weather processing, terrain analysis, hydrology, geostatistics, and geomorphology. Imagery tools include processing, classification, segmentation, photogrammetry, and OpenCV functions. Documented interfaces connect with GDAL/OGR, PostgreSQL, ODBC, and PDAL, while coordinate projection routines use PROJ. SAGA GIS is free and open source: most source code is GPL-licensed, and its API is LGPL-licensed for use in proprietary programs. Windows and Linux are supported; the FAQ says macOS should be possible but reports no experience with it. Windows binaries can run portably after unzipping and launching saga_gui.exe. Linux binaries may need unresolved system dependencies fixed. Support is through the wiki, forums, trackers, and developers, with no hotline or guaranteed support.
