Know exactly where your Mac's storage went — and safely take it back.
The first storage analyzer designed for modern workflows. Understand gigabytes eaten by Xcode DerivedData, Docker layers, Node modules, and local AI model weights (Ollama, LM Studio).
Experience DiskWarren Live on Your Mac
Interact with a simulated 500 GB APFS volume. Toggle between the macOS Radial Partition Ring (Pie Chart) and Treemap matrix to inspect candidate files and simulate safe recycling to Trash.
Macintosh HD — 500 GB Storage Intelligence
Apple Silicon Internal SSD (APFS Container `disk3s1s1`) • macOS 15 Sequoia
Hover or tap slices to inspect APFS partition blocks.
Mac APFS Volume BreakdownTotal: 500.0 GB
Engineered for the Modern Mac
Traditional disk cleaners look for 10-year-old browser caches. DiskWarren was engineered ground-up in native Swift for high-speed APFS storage intelligence.
12,000+ Files / Sec APFS Scanner
Multi-threaded inode traversal scans your entire internal SSD in under 30 seconds with minimal memory footprint and zero CPU thrashing.
100% Local & Zero Telemetry
Completely air-gapped indexing. No file names, directory paths, or disk metrics ever leave your machine. Zero analytics beacons.
APFS Container Transparency
Reveals hidden Time Machine local snapshots, purgeable blocks, and raw container overhead that standard macOS System Settings hides.
Targeting the Culprits Devouring Modern SSDs
Xcode projects, Docker containers, and local LLM checkpoints eat hundreds of gigabytes. DiskWarren classifies them with specialized domain rules.
Developer Ecosystems
Detect and reclaim Xcode DerivedData, archived simulators, stale node_modules trees, Cargo target directories, pip wheel caches, and Docker desktop images.
- Xcode DerivedData, Module Caches & Simulators
- Rust target & Go build cache directories
- Stale dormant node_modules trees in ~/Projects
- Homebrew bottled package download archives
Local AI Storage Intelligence
Local LLMs are SSD monsters. A single 70B quant is 40+ GB. DiskWarren tracks Ollama model blobs, LM Studio GGUF weight files, Hugging Face Hub snapshots, and ComfyUI diffusion checkpoints.
- Ollama (~/.ollama/models) blob translation
- LM Studio & Hugging Face Hub revisions
- Duplicate quant detection (e.g. Q4_K_M vs Q8_0)
- ComfyUI checkpoints & LoRA adapter inspection
Safety First: Zero Accidental Deletions
Never fear running a disk cleaner again. DiskWarren is architected around the macOS Trash with full Put Back restoration and strict system directory blacklists.
Native macOS Trash Integration
All cleaned files are recycled to the native macOS Trash. If you ever need a file back, simply open Trash and click Put Back. Zero raw rm -rf by default.
Permanent System Blacklist
Hardcoded engine barriers strictly protect macOS operating system folders (/System, /usr, /bin), keychains, and sealed APFS snapshots.
Three-Tier Risk Guidance
Every candidate file is tagged as Low Risk (safe caches), Review Required (uninstalled app data), or Restricted, with full preview before action.
See your filesystem as physical space. Zoom, inspect, and drill down.
Our high-speed squarified treemap visualizes millions of files in real time. Click into any directory to reveal exact storage density, locate runaway log files, or sweep away uninstalled application leftovers.
Instant In-Memory Search
Search by filename, extension, or category with sub-10ms response time.
Duplicate Finder (SHA-256)
Three-stage progressive filter: Size bucket → chunk hash → full cryptographic verification.
