DiskScope vs Neodisk

DiskScope is a free, open-source desktop app for analyzing disk usage, finding files, and uninstalling applications. It scans files, folders, and apps in parallel, showing results in a sortable table, tree explorer, and zoomable treemap. Views include application sizes and file-type breakdowns. Fuzzy search filters by type, extension, size, and modified date and is designed to remain smooth beyond 100,000 rows. DiskScope reports actual on-disk usage, including sparse and compressed files. Deleted items move to the Recycle Bin; emptying it permanently clears contents after confirmation. On Windows, the Applications tab shows an installed program’s command before launching its native uninstaller. Disk analysis and search work on Windows, Linux, and macOS. Downloads list Windows 10/11 x64, macOS 12 or later, and Linux x64 builds. The macOS and Linux builds are marked experimental and not tested yet. The app runs locally with no telemetry, according to its maker, and checks for signed updates.

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.
