Our verdict on dua
dua is an MIT-licensed, open-source command-line disk-usage analyzer for developers and other users who want to inspect directory sizes from a terminal. It runs on macOS, Linux, and Windows, and supports both aggregate reporting and interactive exploration. The tool is particularly suited to development environments where Git-related build artifacts and caches can consume space, while its broader directory scanning also fits general file-and-folder analysis.
Its strongest differentiator is the combination of parallel scanning and interactive cleanup. Users can explore files and directories through a terminal interface, then interactively delete or trash unwanted content. Git-aware cleanup discovery targets common development artifacts and caches, while Gitignore-style path exclusion patterns help narrow scans. Depth-limited tree output supports compact inspection, and folded stack output plus SVG flame-graph generation gives technical users additional ways to analyze disk usage or export visual data for flame-graph tools.
The trade-off is a deliberately focused, terminal-first experience. dua does not provide a graphical treemap, application-size reporting, or file-type grouping, so users seeking visual browsing or software inventory should choose a broader graphical analyzer instead. There is also no explicit external-drive scanning feature. For developers comfortable with command-line workflows, its cross-platform availability, open-source license, parallel scans, and cleanup-oriented features make it a practical fit. Users who prioritize a polished desktop interface, application-level reporting, or wider visual integrations should look elsewhere.
