CleanMyDev finding 54 GB on a real Mac — segments expand to show exactly what's inside.

System Data, demystified

Apple won't tell you
what's in there.

Open System Settings → General → Storage and the biggest chunk is usually a gray "System Data" bar.

Apple shows you nothing. On a developer Mac it's almost always 50–150 GB of caches, build artifacts, and AI model files quietly piling up.

CleanMyDev opens that box. Same visual language as Apple's storage panel — but every segment is clickable, named, and safe to clean.

  • Xcode 21 GB — DerivedData, Archives, Device Support
  • Simulators 17 GB — unavailable runtimes, XCTestDevices
  • AI Coding Tools 3.7 GB — Claude Code, Cursor, Codex, Cline
  • Mobile 7 GB — Expo, RN, Flutter, CocoaPods
  • JS/TS 2.9 GB — npm, pnpm, bun, Playwright

Ollama is the new node_modules.

Existing Mac cleaners predate AI coding tools. They miss everything that piled up in the last 18 months.

🤖

Claude Code

Project sessions, plugins cache, file-history. Issue #10107: a known bug ate 300 GB.

📝

Cursor

CachedData, WebStorage, GPUCache. .pack files routinely cross 1 GB each.

⚡️

Codex CLI

Rollout sessions, logs, worktrees. OpenAI issue #17000: tens of GB acknowledged.

🦙

Ollama + LM Studio

Local LLM weights you forgot you pulled. Inspect before delete — never wipe blindly.

🤗

HuggingFace

Hub, datasets, transformers — three separate caches that nobody cleans.

🔨

…and everything classic

DerivedData, simulator runtimes, npm/pnpm/bun, Docker.raw, JetBrains caches, Pods, target/, venv/, __pycache__.

110+ cleanup targets across 16 categories. Updated continuously.

Three steps

No surprises. No subscriptions.

Built like a developer would build it — scan first, review everything, then trash. Trash, not rm -rf.

1

Scan in seconds

Parallel du-based scanner sweeps 110+ paths. Live as it runs.

2

Review every byte

Color-coded safety badges. Click any segment to see paths, sizes, last-modified.

3

Trash — undo from Finder

Default action moves to Trash. Restorable until you empty. Or run official tools like simctl and brew cleanup.

Questions

The honest answers.

Is this safe? What if it deletes something I need? +

Default action is Move to Trash — not rm -rf. Anything CleanMyDev deletes is restorable from Finder until you empty the Trash. Every row has a safety badge (SAFE / QUIT FIRST / REBUILDS / DESTRUCTIVE) so you know what you're doing. Destructive items are never pre-selected.

How is this different from CleanMyMac? +

CleanMyMac is for everyone. CleanMyDev is for developers. We know about 110+ dev-specific paths (Xcode, simulators, AI tool caches, package managers, project artifacts) and we explain exactly what each one is. No "Smart Care" black box. No subscription. One-time $9.99.

Does it work offline? Does it phone home? +

100% offline. Zero telemetry. The only network calls are if you click "open System Settings" to grant Full Disk Access, or click a GitHub link in the menu.

What about my Ollama models? They took hours to download. +

Local LLM weights are tagged DESTRUCTIVE and never pre-selected. You see the size, you click in, you pick exactly which models to remove. CleanMyDev shows the receipts before it touches anything.

macOS version requirements? +

macOS 14 (Sonoma) or later. Universal binary — runs natively on Apple Silicon and Intel.

Will the price stay $9.99? +

Launch pricing is $9.99 for the first 1000 buyers, then it goes to $29.99. Whatever you pay is locked in — all future versions included, forever.

Refunds? +

30 days, no questions. Email a one-liner and you get your money back. The product should pay for itself in the first scan — if it doesn't, get a refund.

Stop wondering what System Data is.

It's your Xcode caches, your Ollama models, your Cursor pack files, your Claude Code sessions. Reclaim them.
