Our verdict on duvis

duvis is an open-source disk usage analyzer for developers, AI agents, and other users who want to understand local storage without deleting files. It scans directories and presents results through a command-line tool, with a local browser interface for visual exploration. Windows, macOS, and Linux support makes it relevant to people working across those operating systems, while the read-only approach suits users who want to inspect storage before deciding what to do themselves.

The range of output is a central strength. In the browser, users can explore a treemap, sunburst, or list view; command-line results can include terminal trees, hierarchical JSON, streaming NDJSON, summaries, and lists of the largest files and directories. Category summaries and filters by category, type, size, name, and modification age help narrow a scan. The product also categorizes entries such as caches, build artifacts, logs, media, version-control data, and IDE metadata, giving technical users several ways to investigate where space is going.

The trade-off is scope: duvis is for understanding usage, not reclaiming space. Its read-only operation avoids making changes during a scan, but users who want an analyzer that also deletes files will need another tool. It is distributed as a command-line tool, so its browser visualizations are part of a local workflow rather than a replacement for the command line. The project is MIT-licensed and free to use; support is through documentation. Choose duvis for cross-platform, visual inspection and flexible output, but look elsewhere if cleanup actions or a standalone graphical-first workflow are essential.
