What Neodisk is

Neodisk is a free, open-source disk space analyzer for Linux and macOS. It helps users inspect storage through treemap, sunburst, and outline views, with zooming, folder navigation, fuzzy search, and keyboard navigation. Analysis tools include largest-file discovery, file-type statistics, an age heatmap, and duplicate finding verified with content hashes. The app is read-only: users can reveal or show files, open them, or copy their paths, but it does not modify or delete them. Completed scans are saved as snapshots for reopening. On macOS, a Changes tab lists additions, deletions, renames, and size changes since the prior scan. Optional Google Drive access reads quota and file metadata, not file contents. The maker says local scan data and file names remain on the device, with no analytics, tracking, or data collection. macOS requires version 14 or later on Apple silicon or Intel. Linux AppImages support x86_64 and ARM64, but Linux rescans are full and lack the Changes and duplicates tabs, cloud-drive scanning, and incremental rescans. Neodisk is licensed under GPL-3.0-or-later.

Who it suits

Neodisk suits people who want to find what occupies disk space without changing files. Linux users should be comfortable with full rescans and fewer features than macOS users.

What it does well

Free and open source under GPL-3.0-or-later.
Treemap, sunburst, and outline views.
Duplicate finding verifies content hashes.
Completed scans persist as snapshots.
Read-only file actions do not modify or delete files.

What to know first

Linux lacks duplicate finding and the Changes tab.
Linux rescans are full scans.
macOS requires version 14 or later.
Linux AppImages require Ubuntu 24.04 or newer.

Limits

The free plan is the GPL-3.0-or-later disk analyzer. Linux lacks duplicates, changes, cloud-drive scanning, and incremental rescans; each Linux rescan is full. The macOS app requires macOS 14 or later, and the Linux AppImage requires a system as new as Ubuntu 24.04.

Getting started

Open the Neodisk GitHub website.
Choose the macOS app for macOS 14 or later on Apple silicon or Intel, or a Linux AppImage for x86_64 or ARM64.
Run a scan of files, folders, or apps.
Reopen completed scans from their saved snapshots.
On macOS, optionally connect Google Drive for quota and file metadata access.

Verdict

Neodisk offers several ways to inspect local storage while keeping file actions read-only. Platform differences matter: Linux omits some macOS features and always performs full rescans.
