StorageSage vs. CleanMyMac vs. DaisyDisk (2026 Apple Silicon Benchmark)
DaisyDisk is a great disk visualizer but lacks a cryptographic duplicate detector, an app orphan uninstaller, or an automated developer cache cleaner. CleanMyMac X bundles utilities together but installs persistent background daemons (~260 MB) and charges $39.95+/year. StorageSage combines a 55.3× faster BSD fts_open disk scanner, a Tri-Window pread SHA-256 duplicate finder, a 14+ ecosystem Developer Cache Cleaner, an App Uninstaller, and a reversible SHA-256 Audit Log inside a 3.8 MB native Swift binary with zero background daemons for $10/year (up to 3 personal Macs).
Head-to-Head Architecture & Feature Matrix
| Dimension | StorageSage 1.0 | CleanMyMac X | DaisyDisk | Pearcleaner |
|---|---|---|---|---|
| Filesystem Traversal Engine | BSD fts_open (FTS_PHYSICAL | FTS_NOCHDIR) · 55.3x faster | High-level Objective-C / XPC privileged helper | Proprietary parallel C/Objective-C scanner | NSFileManager directory enumeration |
| App Bundle Footprint | 3.8 MB native Swift + SwiftUI | ~260 MB + persistent background Menu & Health daemons | ~18 MB native macOS binary | ~12 MB SwiftUI binary |
| Background LaunchAgents / Daemons | Zero (0% idle CPU & 0 MB background RAM) | Multiple persistent root daemons & login items | Zero | Optional helper monitor |
| Cryptographic Duplicate Finder | Tri-Window pread + APFS inode dedup + full SHA-256 (8.1x faster) | Basic clutter module | Not included (Visualizer only) | Not included (App uninstaller only) |
| 14+ Developer Toolchain Cleaner | Xcode, Simulators, Docker, Cargo, Gradle, npm, pnpm, CocoaPods, Conda | Basic Xcode cache toggle | Manual folder inspection only | Not included |
| Reversible Audit Log (Finder Put-Back) | SHA-256 AuditLog + 1-click Finder Put-Back restore | Direct permanent deletion by default | In-app collector before deletion | Moves to Trash |
| AI Safety Advisor ("Is this safe to delete?") | Built-in on-demand AI Safety Advisor (zero file contents uploaded) | Static curated database | None | None |
| Pricing Model (Up to 3 Macs) | $0 Free Demo / $10 per year Pro Annual | $39.95 – $89.95 per year subscription | $9.99 single-purpose visualizer | Open-source uninstaller |
Uses BSD fts_open (FTS_PHYSICAL | FTS_NOCHDIR) with post-order package rollup to scan 50,000 files in 0.42s vs. 23.2s with Foundation enumerators.
Combines exact byte-size bucketing, APFS (st_dev, st_ino) hard-link deduplication, and 4 KiB Tri-Window pread sampling before full SHA-256 verification.
Lock-free civil-calendar APFS snapshot parser + multi-core st_blocks * 512 physical block attribution across ~/Library in 0.18s.
