In their own words
agedu
agedu is a free, MIT-licensed Unix utility that scans directory trees and relates disk usage to file access times. It helps locate large data that has gone unused, but it cannot decide whether a file is safe to delete. It produces text and HTML reports, or can serve navigable HTML reports through a small built-in web server. In HTML reports, colours distinguish disused data in red from recently accessed data in green. Text reports can be limited to files not accessed within a chosen age, such as six months. Scan settings can cross filesystem boundaries and include, exclude, or prune files and directories. Results can be written as text on one machine and loaded into an index on another, including across different CPU architectures. Index files use restrictive permissions because they may reveal confidential filesystem information. By default, the built-in server uses Linux user-based access checks or HTTP Basic authentication with an invented password when those checks are unavailable. CGI mode has no access control of its own. There is no native Windows port, though a separate Windows scan utility can create a dump for loading into agedu on Unix.
Neodisk
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.
