See what's taking space.
A disk space analyzer for macOS, not an automatic cleaner.
Scan locally, see exact paths and sizes, and decide what to remove yourself. Nothing is deleted without your say.
See the evidence
Treemap, large files, Duplicate Review, leftovers, and storage hotspots stay visible before any cleanup step.
Review the risk
Nothing is deleted without your approval. Dry Run shows the exact paths and sizes before anything applies.
Track change locally
Snapshots, reports, and cleanup history stay on your Mac. No cloud sync. No account required.
The App Store version is the standard path for most users. Need broader filesystem access for advanced analysis workflows? See the Direct build
Free to scan and review. Cleanups move to Trash by default. One-time purchase to apply.
Scan first. Decide second. Act third.
StorageRadar is built around deliberate action: analysis and cleanup are always separate steps.
01
Scan your storage
Choose a scan source: Home folder, Developer folder, System Volume, or a custom directory. The scanner indexes your files and shows live metrics as it goes.
02
Visualize and explore
Navigate your disk through Treemap or Sunburst. Browse largest files. Find apps with leftover bloat. See exactly what's using your space before you do anything.
03
Clean with confidence
Dry-run first and see what would be removed. For risky operations, step through a pre-apply review that shows exactly what changes. Then apply: move to Trash with undo support or delete permanently.
Understand your storage before you touch a single file
StorageRadar is built for evidence first: visualize what is using space, resolve permissions blockers, compare snapshots over time, then act locally with full review.
Storage Cleanup
Treemap and Sunburst views turn disk usage into evidence you can inspect. Shortlist candidates, review exact paths, and build a cleanup batch in the global Collector bar before any destructive action. Use Duplicate Review to group exact file copies, compare potential savings, preview selections, and move verified duplicates to Trash only after review.
- Treemap & Sunburst visualization
- Largest files with filters & search
- Duplicate Review for exact file copies
- Global Collector bar for batch operations
- Preview-first cleanup before Move to Trash or Delete
Dev Cleanup
Developer environments mix rebuildable caches with workflow-sensitive data. StorageRadar separates the two, adds ecosystem context, and lets you inspect profiles, dry-run risky actions, and step through a safety review before apply is unlocked.
- Xcode, npm, Docker, Gradle & more
- Safe / Caution / Dangerous risk levels
- Dry Run & step-by-step review before apply
- Developer tier unlock for apply actions
Reports & Snapshots
Capture snapshots locally, then compare what grew, shrank, appeared, or disappeared when storage management needs evidence over time, not just a one-time panic cleanup.
- Point-in-time snapshot capture
- Snapshot history with baseline / target selection
- Grew / Shrank / New / Removed diff
- JSON, Markdown, CSV export

Permissions & Access
When macOS blocks access, StorageRadar tells you exactly which path is affected and what permission is missing. The blocker stays visible instead of disappearing into a black box.
- Accessible / Blocked / Missing counts
- Per-path recovery hints
- Full Disk Access & App Management
- Changed paths tracking
App Uninstaller
Apps leave support files across caches, containers, preferences, and logs. StorageRadar shows the residue path by path so you can inspect the uninstall plan, re-check access, and preview the result before apply.
- Complete leftover detection
- Risk labels: Ready / Needs Check / Blocked
- Preview Removal before apply
- Re-check Access for blocked coverage
MCP Integration
Optional local integration. Run a read-only endpoint on 127.0.0.1 that AI agents can query for disk analytics. No file access, no deletion capability: just aggregated insights over a secure local connection.
- Local MCP endpoint (127.0.0.1)
- Read-only, zero file access
- Token-based authentication
- Configurable path privacy policy
Your storage data stays on your Mac.
Your files never leave your Mac. Scan sessions, snapshots, reports, and cleanup history all live in ~/Library/Application Support/StorageRadar/ on this machine. The only outbound signals are optional feature-level analytics (which workflows ran, not what was inside) and crash reports. Both are off by default in Settings, and neither carries file paths or scan contents.
Storage data stays local
Scan sessions, indexes, snapshots, reports, cleanup history, and local usage metrics live on this Mac.
No cloud sync for storage data
There is no StorageRadar account and no remote workspace for your scans, reports, or cleanup history.
Analytics cannot see your files
Usage analytics receive feature-level events: which workflows ran, not what was inside them. No file paths, names, scan contents, or MCP tokens ever leave the app.
Crash reports are opt-out
Crash diagnostics use Sentry. Scan contents are never attached. You can turn delivery off in Settings at any time.
Local-only MCP endpoint
The AI integration runs on 127.0.0.1 and stays read-only: no delete, move, or file-content access.

FAQ
Common questions
Yes. The Free tier keeps preview mode across Disk Analysis, App Uninstaller, Dev Cleanup, and Reports. You can inspect results, run Dry Run, Preview Removal, or Guided Preflight where applicable, and capture local snapshots before you unlock paid apply actions or Reports comparison and export.
Yes. StorageRadar supports Apple's Family Sharing for eligible one-time App Store purchases. Availability still depends on the Apple family group, purchase sharing settings, and App Store account state.
Yes for core workflows. Scanning, analysis, visualization, dry-run, permissions diagnostics, snapshots, reports, and local MCP access work on-device. Network is only needed for App Store purchases or restore flows and, if you keep them enabled, privacy-safe product analytics or Sentry diagnostics and feedback.
Core storage data stays local: scan indexes, cleanup history, snapshots, reports, and local usage metrics stay on-device. StorageRadar also has separate remote channels for privacy-safe product analytics (Aptabase) and diagnostics or feedback (Sentry). Remote delivery does not include scan paths, file names, bundle identifiers, snapshot labels, raw scan payloads, MCP secrets, or raw error text, and scan files are not attached automatically. Both can be turned off in Settings.
StorageRadar is not a one-click cleaner. It's built around a deliberate workflow: scan → visualize → review → act. Nothing is deleted automatically. Every cleanup requires your explicit decision, and risky operations require dry-run or guided preflight first. You're always in control.
Yes. Duplicate Review finds exact duplicate files, groups them for comparison, shows potential savings, and lets you preview selections before moving anything to Trash. It is review-first, not automatic cleanup.
Dry Run simulates a cleanup operation without deleting or moving anything. You see exactly what would be affected (paths, sizes, risk levels) before committing. For risky developer profiles, there's also a Guided Preflight that walks you through potential consequences step by step before unlock.
Move to Trash supports a quick undo window: you can restore items from Trash via Finder afterward. Delete Permanently does not support undo. StorageRadar always makes the distinction clear and asks for confirmation before any permanent deletion.
Dev Cleanup covers Apple (Xcode derived data, simulators, archives), Web (npm, yarn, node_modules), Backend (Gradle, Maven, pip), Android (SDK, AVD), Data science environments, and Containers (Docker with full prune integration). Each ecosystem has specific cleanup profiles with appropriate risk classifications.
It runs a local read-only HTTP endpoint that AI assistants (like Claude via MCP) can query for disk analytics and scan data. It doesn't give AI agents any ability to delete files; it's purely informational, letting your AI tools understand your storage situation without direct filesystem access.
macOS protects certain directories (Desktop, Documents, app containers, and system volumes) from direct access. The Permissions section shows exactly which paths are blocked and gives you step-by-step guidance to grant appropriate access: folder-scoped permission, Full Disk Access, or App Management.
Largest shows the biggest files and folders in your current scan. Reports starts with local snapshots, so you can keep history over time. Free and Core can capture snapshots and review that history; Developer unlocks diff and export to answer 'what grew, shrank, appeared, or disappeared?'
Distribution Paths
Start with the App Store. Use the Direct build when you need broader access.
The App Store release is the standard path for most users. The Direct build is available for advanced cleanup workflows that can require broader macOS access than App Store sandboxing reliably allows.

Build history
Recent release history. Each build ships what is actually stable.
Added
- Buy and upgrade right inside the app: get Core or Developer straight from the Unlock screen, with checkout opening securely in your browser and your license key arriving by email within minutes
- One-tap upgrade from Core to Developer that unlocks Dev Cleanup for Xcode, Docker, and caches plus Reports compare and export, without re-buying
Improved
- Clearer Unlock screen that puts buying front and center, with "Already have a license key?" and App Store recovery tucked into tidy collapsible sections
- Less guesswork at checkout: a hint shows which address your key email comes from, and a Contact support button appears if a key reaches its device limit
- Full, natural localization across all 10 languages — English, German, Spanish, French, Japanese, Korean, Dutch, Portuguese (Brazil), Russian, and Simplified Chinese — with no more screens falling back to English
- One-time purchases, no subscription ever, and nothing removed automatically: every cleanup still asks for confirmation and Move to Trash can be undone
Added
- New first run that starts you on a safe Home Folder scan instead of a generic welcome, with confirmation always required before anything is removed
- Accessible risk levels: safe, caution, and danger now read by icon as well as color, with full Increase Contrast support
Improved
- A refreshed, more native look across every screen, with flatter surfaces, lighter shadows, and consistent spacing for a calmer, clearer app
- Calmer Home with a disk-space overview at a glance and quieter, easier-to-scan cards
- Duplicate Review now matches the app's light theme, with larger text, less on-screen clutter, and scan progress that stays visible while scanning
- Clearer Unlock screen with a recommended plan, benefit-focused wording, and a reclaimable-space estimate
Added
- Duplicate Review now finds exact duplicate folders, not just files, confirmed by a full content fingerprint so only genuinely identical folders are grouped for review
Improved
- Faster exact-folder matching that reuses an in-memory index and partial content hashes to skip unnecessary full-file reads on large Home folders
- Safer broad scans, with exact-folder matching skipping Library, Trash, caches, and app containers, the same protected areas already excluded for files
- Cloud-aware by default: cloud-only files and provider placeholders are skipped before any read in local-only mode, so nothing is downloaded just to scan it
- Hardlink-aware savings estimates so the reclaimable space shown reflects what you would actually get back
- Steadier progress during long folder scans instead of going quiet until the end
