In their own words
Neodisk
Neodisk is a free, open-source disk space analyzer for macOS and Linux. It scans files, folders and applications, then presents storage usage in treemap, sunburst and outline views. Zooming, folder navigation, fuzzy search and keyboard navigation help you move through a scan. Analysis includes largest-file discovery, file-type statistics, an age heatmap and duplicate finding verified with content hashes. Neodisk is read-only: available file actions are revealing an item in Finder or Files, opening it and copying its path. Completed scans persist as snapshots that can be reopened. On macOS, the Changes tab records additions, deletions, renames and size changes since the previous scan. Optional Google Drive access reads quota and metadata without reading, downloading or changing file contents. macOS requires version 14 or later on Apple silicon or Intel. Linux AppImages support x86_64 and ARM64, but Linux lacks duplicate and changes tabs, cloud-drive scanning and incremental rescans.
