Neodisk
Neodisk is a free, open-source disk space analyzer for Linux and macOS.
What Neodisk is
Neodisk is a free, open-source disk space analyzer for Linux and macOS. It maps files and folders in treemap, sunburst, and outline views, with zooming and folder navigation to help locate what occupies storage. Analysis tools include largest-file search, file-type statistics, an age heatmap, and duplicate finding verified with content hashes. Fuzzy search and keyboard navigation support moving through a scan. Neodisk is read-only: its file actions let you reveal or show an item, open it, or copy its path, rather than change or delete it. Completed scans persist as snapshots for reopening. On macOS, a Changes tab reports additions, deletions, renames, and size changes since the prior scan; optional Google Drive access reads quota and file metadata, not file contents. Linux lacks the Changes and duplicates tabs, cloud-drive scanning, and incremental rescans, so each rescan is full. macOS requires version 14 or later on Apple silicon or Intel; Linux AppImages are offered for x86_64 and ARM64.
Good
- Treemap, sunburst, and outline views
- Largest-file search and file-type statistics
- Completed scans persist as snapshots
- Read-only file actions avoid modification or deletion
- Free and open-source under GPL-3.0-or-later
Watch out
- macOS requires version 14 or later
- Linux lacks duplicates and changes tabs
- Linux rescans are full scans
- Linux has no cloud-drive scanning
Who it suits
Neodisk suits people who want a visual, read-only way to inspect local disk use and find large files or duplicates. Mac users can also review changes between scans and optionally inspect Google Drive metadata; Linux users should note the listed feature limits.
Verdict
Neodisk combines several storage views with practical file analysis while keeping file operations read-only. Its feature set varies by platform, so Linux users should weigh the missing tabs and full-scan-only workflow.
