agedu vs Disk Usage Analyzer

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.

Disk Usage Analyzer is a free Linux desktop app for checking how storage is used and how much space remains. It scans selected folders, storage devices, and online accounts; external drive scans are also supported. Results present folder sizes in a tree view and a graphical representation, so users can inspect how a scan’s contents are distributed. The app page directs users to install the latest version from Flathub, which lists aarch64 and x86_64 architectures. The GNOME app page lists version 50.0, released on 2026-03-13, and names Paolo Borelli, Stefano Facchini, and Christopher Davis as maintainers. Users can report issues or suggest ideas through the app’s issue tracker. Flathub labels the app “Medium Risk.” The plan is listed at free. The app page does not identify which online account services can be scanned, and it does not state security certifications or compliance details.
