Neodisk vs StorageRadar

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.

StorageRadar is a macOS desktop tool for examining disk use across files, folders, and applications. It reports application sizes and file-type breakdowns, with exportable reports. Treemap and Sunburst views present storage distribution, while local snapshots and history retain scan records. The Free plan costs nothing and includes deep storage scanning, preview access across Disk Analysis, Duplicate Review, App Uninstaller, and Dev Cleanup, plus permissions diagnostics and local MCP integration. The Core plan is listed at $9.99 a month, with a one-time purchase noted. Its added actions include moving items to Trash with an undo window, permanent deletion, applying storage cleanup, and applying app uninstalls. The Developer plan is listed at $19.99 a month, also with a one-time purchase noted. It adds Dev Cleanup actions, ecosystem profiles, report comparisons over time, and JSON, Markdown, and CSV export. The listed desktop platform is macOS.
