Burrow Top pick
Free open-source native Mac cleaner and system companion
Metadata checked Aug 18, 2026
Best GUI match: broad CleanMyMac-like coverage, a native macOS interface, and current signed/notarized releases. Its long-term track record is shorter than Mole's.
A native SwiftUI menu-bar app covering previewable junk cleanup, developer-artifact purging, app removal with leftovers, disk maps, maintenance tasks, and live system monitoring.
- 01 Preview and remove caches, logs, leftovers, and developer artifacts
- 02 Uninstall apps with preferences, support files, and launch agents
- 03 Disk treemap, duplicate discovery, and installer cleanup
- 04 Maintenance actions and Homebrew update management
- 05 Live CPU, memory, GPU, disk, network, battery, and history views
- Requires macOS 14 or later.
- Some scans and cleanup actions need Full Disk Access or administrator approval.
- The app sends opt-out anonymous usage and crash diagnostics; its telemetry is documented in the repository.

Mole
Free open-source all-in-one Mac maintenance toolkit
Metadata checked Aug 18, 2026
Strongest maintenance and community signal with the broadest free feature set, but the qualifying product is terminal-first. The author's native GUI is a separate paid application.
Full review — capabilities, 3 caveats, evidence
A mature GPL-3.0 terminal toolkit for deep cleanup, app removal, disk analysis, optimization, project-artifact purging, installer cleanup, and live system status.
- 01 Clean caches, logs, orphaned app data, and temporary artifacts
- 02 Uninstall apps with launch agents, preferences, and hidden remnants
- 03 Analyze disk usage and remove large installer files
- 04 Optimize caches and system services
- 05 Monitor CPU, GPU, memory, disk, network, and battery status
- 06 Dry-run previews, whitelists, and local cleanup history
- The free open-source core is the CLI; the native GUI at mole.fit is proprietary and paid.
- Some cleanup commands can permanently remove selected artifacts, so review dry-run output and whitelists.
- Homebrew installation is documented for macOS 14 or later; older versions use a best-effort script installer.

Krokiet
Open-source cross-platform GUI for finding reclaimable files
Metadata checked Aug 18, 2026
Best focused storage-cleanup companion: active Krokiet development, mature algorithms, free binaries, and explicit macOS support. It is narrower than CleanMyMac and does not manage apps or system performance.
Full review — capabilities, 4 caveats, evidence
The actively developed GUI frontend of Czkawka, using a Rust scanning engine to find duplicates, large or empty files, temporary data, similar media, and other file problems on macOS.
- 01 Find duplicate files by name, size, or hash
- 02 Find large, empty, temporary, broken, and incorrectly named files
- 03 Compare similar images, videos, and music
- 04 Detect invalid symbolic links and file extensions
- 05 Remove selected files and clean EXIF metadata
- 06 Prebuilt macOS binaries for Apple Silicon and Intel
- No app uninstaller, malware scanner, or general system-optimization suite.
- Optional similar-video and extra image-format features need tools such as ffmpeg and native libraries.
- The legacy Czkawka GTK frontend is deprecated; use Krokiet, the current recommended GUI.
- The project states that it has no separate official website; GitHub is the official project home.
