An elegant interface, powerful tools — built for developers and demanding Mac users.

NythyCleaner

Desk Mac and dev workflow, in one tool

Whether you run a workstation, engineer laptop, or build box: 22 Xcode categories, full Docker management, iCloud Drive treemap, exact SHA-256 duplicates — all with charts and a readable cleanup UI.

  • Xcode cleanup

    22 categories: DerivedData, archives, all simulator platforms (iOS/watchOS/tvOS/visionOS), SwiftUI Previews, SwiftPM, Carthage, CocoaPods, Tuist, Mint, Fastlane, provisioning profiles, old runtimes — charts before every delete.

  • Monitoring

    Overview with live charts and adjustable refresh; tabs for CPU (with core controls where available), memory, GPU, Neural Engine, network, disk I/O, processes, and thermal readouts when the hardware exposes them.

  • Security audit

    Scan dev projects for known vulnerabilities (CVEs) across npm, pip, Go, Deno, CocoaPods, Maven, Composer, and Bundler — powered by govulncheck, osv-scanner, and OWASP Dependency-Check with live per-manager progress.

  • Dev dependencies

    20 ecosystems scanned: Node/npm, Python, Rust, Go, Flutter, CocoaPods, Gradle, Ruby, .NET, PHP/Composer, SPM, Maven, Deno, Bun, Elixir, CMake, Haskell, Zig and more — grouped by ecosystem with smart disambiguation via project markers.

Development & toolchain

  • Homebrew & Docker

    Homebrew formulae, casks, and caches. Docker images (dangling or all unused), stopped containers, unused volumes, networks, build cache, and full system prune — complete inventory before any purge.

  • Disk space

    Hierarchical treemap for any local volume. Large- and old-file scans with size and age filters. Expert disk utility: format, rename, and repartition volumes from inside the app.

  • Exact duplicates

    Byte-for-byte matching: recursive directory walk, same-size groups, and a full SHA-256 over each file — true duplicates even when names or dates differ.

  • Dev package updates

    Detect outdated packages across 15 managers (npm, Yarn, pip, Composer, Cargo, Go, RubyGems, .NET, Maven, CocoaPods, Bundler, Flutter/Dart, Bun, Deno) — update individually or in bulk by package name, or install new packages globally or per-project with one click.

  • iCloud Drive

    Hierarchical treemap of your iCloud Drive showing local vs. cloud-only files — evict or re-download individual items directly from the panel.

Desktop & system maintenance

  • System cleanup

    Caches, logs, temp files, downloads, Trash — donut and distribution charts, ranked largest files, path exclusions, cleanup history over time, plus Safari and browser extensions listed for review.

  • Scheduled cleanup

    Automate daily, weekly, or monthly runs.

  • Extensions

    Quick Look generators, Spotlight importers, LaunchAgents, daemons, and related entries — see what loads and toggle what the system allows.

  • System information

    Hardware, OS, memory, volumes, battery, and network — full technical readout.

  • Uninstaller

    Apps and leftover files — reclaim space cleanly.

  • Menu bar & Widget

    CPU gauges in the menu bar for at-a-glance monitoring; WidgetKit widget (small, medium, large) showing CPU, memory, GPU, Neural Engine, network, and disk I/O.

  • System maintenance

    Guided maintenance tasks: DNS flush, Spotlight and LaunchServices repair, RAM pressure relief, icon and log utilities, plus an app-updates overview — run only what you select, with confirmations.

  • Privacy

    Privacy score, TCC permissions audit, system traces, network history, and browser data — with multi-pass secure delete (DoD).

The full depth, not just the headlines

These capabilities ship in the app — local processing, no extra plug-ins. Use the list below as a checklist of what you can do beyond the cards above.

  • Monitoring overview with combined charts and refresh intervals from 0.5 s to 5 s
  • Per-subsystem tabs: CPU, memory, GPU, Neural Engine (Apple Silicon), network throughput, disk I/O, and processes
  • End a runaway process from the process list when allowed; Pro is required to confirm a kill
  • Thermal and sensor cards when your Mac exposes them
  • Xcode cleanup across 22 categories: DerivedData, all simulator platforms including visionOS, SwiftUI Previews, Carthage, CocoaPods, Tuist, Mint, Fastlane, provisioning profiles, old runtimes
  • iCloud Drive hierarchical treemap with per-file eviction and download actions

The essentials are free. Go Pro to unlock everything.

Analyze and monitor without limits. Advanced actions (bulk delete, uninstall, duplicates, scheduled cleanup) require a Pro subscription.

14 days of full Pro — no account, no credit card, 100% local activation on your Mac.

Frequently asked questions

Everything you should know before you start.

Is the app really free?
Yes. Disk analysis (treemap and scans), full monitoring (including overview, GPU, Neural Engine, network, disk I/O, and thermals when available), hardware information, and the Extensions sidebar are free. Advanced actions (bulk delete, uninstall, duplicates, scheduled cleanup, killing processes from the monitor) require a Pro subscription.
How does the Pro subscription work?
You subscribe from inside the app after downloading from this website: 14 days of full Pro, no account or credit card required, with 100% local activation on your Mac. Then pick the plan that fits: monthly (€5.99), yearly (€49.99), yearly Family for 3 Macs (€79.99), or a one-time Lifetime license (€129). Subscriptions can be cancelled anytime via the Stripe customer portal (link in your email) or the "Manage subscription" button in the app. NythyCleaner is not on the Mac App Store at this time.
Is my data sent to your servers?
No. NythyCleaner runs locally on your Mac. Analysis, preferences, and deletions stay on your machine. Subscription checks may go through our secure backend and the payment provider — we do not collect usage telemetry.
What does the security audit do?
The security audit scans your dev projects for known vulnerabilities (CVEs). It uses govulncheck for Go, osv-scanner for Deno and CocoaPods, OWASP Dependency-Check for Maven, and native audit commands for npm, pip, Composer, and Bundler. A live scan page shows progress per package manager, severity badges (critical, high, moderate, low), and a detailed report you can copy.
How does the privacy audit work?
The Privacy screen assigns a score to your Mac by auditing TCC permissions (camera, microphone, disk access…), system traces, network history, and browser data. You choose what to clean, with an optional multi-pass secure delete (DoD) for sensitive files. Advanced delete modes require Pro.
Is it safe to clear system caches?
Yes. Caches are temporary files recreated by apps. NythyCleaner never touches your documents, photos, or personal data. Note: System Cleanup and Xcode Cleanup delete files permanently (not via Trash). A confirmation is always shown before any deletion.
Which macOS version is required?
NythyCleaner requires macOS 14 (Sonoma) or later. On macOS 26 (Tahoe), the app uses native Liquid Glass where available. The SwiftUI interface is optimized for Apple Silicon and also works on Intel.
Is there a macOS widget?
Yes. A WidgetKit widget (small, medium, large) shows CPU, memory, GPU, Neural Engine, network, and disk I/O from the desktop or Notification Center. A menu bar icon also provides quick access to metrics.
Can I recover files deleted by mistake?
By default, files are moved to Trash. You can restore them until Trash is emptied. A confirmation is always required before deletion.
How do I report a bug or request a feature?
Email contact@nythycleaner.cloud. We read every message and reply quickly.
