SpaceBrowser
What SpaceBrowser is
SpaceBrowser is a free disk-space analyzer for Windows and Linux, with a macOS build also available. It scans a folder or volume and displays files and directories in a treemap sized according to their storage use, making larger items easy to identify. Scans show elapsed time and file and folder counts, can be canceled, and report skipped paths or filesystem and metadata errors. Users can exclude paths, hidden files, symlinks and network filesystems. A live cache uses filesystem change detection to speed rescans during the current session. The app can open files and folders, move items to trash, or delete them permanently; the project describes safeguards for sensitive locations such as system paths, mount points and special files. Treemap colors, scale, shape, shading and hover highlighting are adjustable, as are keyboard and mouse bindings. Downloads include MSI and portable EXE options for Windows, DEB/RPM and a portable binary for Linux, and DMG/ZIP for macOS. The project says its macOS build has not yet been tested. SpaceBrowser is MIT-licensed and can also be launched from a terminal.
Who it suits
SpaceBrowser suits people who want to locate large files or folders visually and review what a scan skipped or encountered as an error. Its multiple scan exclusions and desktop platform builds may fit users who want to tailor disk analysis.
What it does well
- Free and MIT-licensed
- Treemap sizes reflect file and folder sizes
- Scans can be canceled
- Exclusions cover hidden files and network filesystems
- Deletion safeguards cover sensitive filesystem locations
What to know first
- The macOS build has not yet been tested
- Open reports concern scan speed and an Ubuntu error
- Settings-window focus is also an open issue

As github.com lists them, read 12 Oct 2026. The maker's own page has the final word.
Verdict
SpaceBrowser offers a configurable treemap and scan controls across desktop platforms. Windows and Linux support is listed, while the macOS build remains untested, so users on that platform should take that limitation into account.
