An open-source, transparent, and privacy-first macOS system cleaner, storage analyzer, and developer-cache manager.
- Smart Scan: Unified discovery of system caches, application logs, temporary files, and Trash items.
- Developer Cache Cleaner: Targeted cleaning of Xcode DerivedData, SPM caches, CocoaPods, Gradle, Android build caches, npm, pnpm, Yarn, Bun, Homebrew, and Docker artifacts.
- Interactive Storage Analyzer: Visual folder tree and disk usage breakdown.
- Large File Finder: Discover large files over configurable thresholds (500 MB to 10 GB+).
- Safe Duplicate Detection: Multi-stage content hash engine for discovering duplicate copies safely.
- App Uninstaller: Complete leftover file discovery for uninstalled applications.
- Safety First: Hardcoded system safeguards, symlink resolution, explicit review, and confirmation before cleanup.
- Secure Updates: Automatic updates signed with a dedicated Sparkle EdDSA key.
- Privacy First: 100% local scanning, zero telemetry, zero analytics tracking, zero cloud server uploads.

MacSweep decouples file discovery from deletion:
[ Scanner Engine ] ──▶ [ Safety Validator ] ──▶ [ User Review ] ──▶ [ Confirmed Cleanup ]
- Scanner: Read-only path enumerator. Cannot delete files.
- Safety Validator: Validates candidate paths against system boundaries (
/System,/usr,/Library/Keychains) and verifies canonical symlinks. - Cleanup Engine: Permanently removes approved cleaner items. Large Files and App Uninstaller remain recoverable through the macOS Trash.
