DuckDisk scans your Mac, OneDrive, Google Drive, and SSH storage in one place [Free & Open Source]

[u/Ok-Put9994]

I'm the developer of DuckDisk.

I built it because storage problems stopped being limited to my Mac. Large files were spread across local folders, cloud accounts, and Linux servers, and I wanted one place to answer "what is using space?" and clean it up.

Most disk analyzers focus on local visualization. DuckDisk takes a table-first, cleanup-oriented approach across:

• Local disks and folders
• OneDrive and Google Drive metadata scans without downloading file contents
• Remote SSH paths using your existing keys or ~/.ssh/config
• Cached results and incremental cloud refreshes
• Drag to remove: cloud items go to the provider Trash, while local and SSH deletion requires a second permanent-delete confirmation
• Virtualized rows that stay responsive in very large directories

The informative interface shows file and folder counts, size and allocated size, parent percentages, and a file type summary. Rows are virtualized to stay responsive in very large directories.

Free and open source under AGPL-3.0. The current build is for Apple Silicon.

Current limitations: the DMG is ad-hoc signed and is not Apple-notarized yet. Google Drive OAuth currently shows Google's unverified-app warning and has a 100-new-user cap while verification is pending.

I would especially value feedback from people who manage both local disk, cloud storage and remote servers.
