Neodisk vs Space Wizard

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.

Space Wizard scans files and folders on Windows, macOS and Linux, including external drives. Scan locations can include selected folders, whole drives, multiple drives, and shared or NAS folders. It can look for matches using SHA-256 content hashing, byte-for-byte exact matching, or recursive folder-content matching, and supports sending items to the Recycle Bin or Trash. Its Free plan costs nothing, is free forever, requires no card and covers the home drive up to 100 GB per scan. The product does not offer a treemap view, application sizes or a file-type breakdown. It also lacks automatic selection, so scan locations and matching methods are chosen by the user. Space Wizard is cross-platform and comes from a maker founded in 2024 and headquartered in Kragujevac, Serbia.
