Drive Atlas vs Neodisk

Drive Atlas catalogs drives so users can search for files even when the drive containing them is unplugged. Search by file name, project, or date range, then see which drive holds a file and where that drive is located. A treemap shows drive contents, including offline drives. The app can find files that exist in only one place, verify backup copies by hashing both sides, and check duplicate groups byte for byte before moving selected copies to the Recycle Bin. Drive health tools benchmark drives over time and can list unique files on a failing drive for evacuation. It also analyzes numbered image sequences for timelapse interval and steadiness, and creates printable QR labels with drive summaries. The maker says the app makes zero network connections and does not interpret image content or use AI. Drive Atlas runs on Windows and Linux. The free plan covers the first two drives and includes all features, with no card or timer; the one-time license is 20.00 USD for all drives.

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.
