Ansel – OSS volume visualization tool

15 hours ago

Ansel is a free, open-source disk space analyzer for macOS, Linux, and Windows, offering visualizations like treemaps and sunbursts.
It provides features like file categorization, heatmaps by modification age, case-insensitive search, and marking files for deletion with two-step confirmation.
The tool operates locally without network requests, includes build provenance attestations for security, and supports platform-native file manager integration.
Ansel measures on-disk allocation, which can differ from system reports due to factors like partial blocks, purgeable space, and APFS clones.
On macOS, users may need to bypass Gatekeeper for unsigned apps and grant Full Disk Access to scan protected directories.
The software is in beta, primarily tested on macOS, and encourages bug reports for issues on other platforms.
