Disk Usage Analyzer vs OmniDiskSweeper

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.

OmniDiskSweeper is a free macOS utility that displays files on a drive from largest to smallest. This ordering helps users locate large unwanted files, open them, or remove them. Moving items to the Trash is the default action; holding the Option key enables direct deletion instead. The utility can scan external drives. Omni says the version compatible with macOS 26 makes the entire app accessible with VoiceOver, and the product page lists older downloads for macOS 10.4 through 10.13. The freeware download requires no form or personal information. Omni says it does not share data gathered from its apps or websites with social media or advertising services. Support is available by email and phone Monday through Friday, 10am–5pm Pacific Time. The company notes that OmniDiskSweeper is updated less frequently than its other titles, although it still receives updates. The Omni Group is employee-owned and based in Seattle, Washington.
