agedu vs LumaDisk

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.

LumaDisk is a disk space analyzer for macOS and Windows that maps a filesystem to show what is using storage. Its interactive sunburst and treemap views update during a scan. The app groups regenerable developer folders such as node_modules, /target,.next, and DerivedData, and groups duplicate files with one copy selected to keep. It also lists files of at least 100 MB that have not been opened for six months, a year, or two years. External drives are fully supported; network volumes can be analyzed read-only. Cloud support includes iCloud Drive, OneDrive, and Dropbox, while Google Drive is described as coming soon. The free plan keeps scanning and the sunburst view available. A LumaDisk license is listed at $6.89 a month, billed as a one-time payment rather than a subscription, and covers up to five Macs. Requirements are macOS 12 or later on Apple Silicon, or Windows 10 or later on x86-64 or ARM64. Reclaim permanently deletes files, with a ten-second undo window and safeguards against queuing system folders.
