Our verdict on Neodisk
Neodisk is a free, open-source macOS application for examining storage usage across files, folders, and apps. It is aimed at Mac users who want more than a one-time largest-file search, particularly those who value scan history and visual analysis. Treemap and sunburst views provide two ways to understand disk usage, while file-type statistics, largest-file search, and fuzzy search help narrow attention to specific storage patterns. The app is read-only, so it focuses on inspection rather than cleanup actions.
Its strongest distinction is the depth of its scan history. Neodisk can save snapshots of completed scans and track changes between scans, giving users a way to compare storage over time instead of starting from a blank report each time. The content-hash-verified duplicate finder adds a verification step for duplicate analysis. Finder actions such as Reveal, Open, and Copy Path connect the results to common file-management workflows without making Neodisk responsible for deleting or modifying files. Scans are processed locally, and the application is distributed as a downloadable DMG or through Homebrew.
Platform fit is focused: Neodisk requires macOS 14 or later and does not present a cross-platform workflow. Its Google Drive integration scans metadata, extending visibility beyond local disks while keeping the product centered on analysis. Users who want a free, open-source Mac tool with visual reports, duplicate verification, snapshots, and change tracking should consider Neodisk. Users seeking built-in deletion or modification tools, or a broader platform footprint, should choose a different analyzer.
