# How to Vibe Code Your Own MacPaw (and Stop Paying for It)

- Verdict: **Don't bother** (25/100 vibecodeable)
- Estimated effort: 6+ months of full-time work

## Verdict

Keep paying for CleanMyMac or Setapp; building a full native optimization and security suite with kernel-adjacent disk scanners involves massive macOS engineering overhead.

While an AI coding agent can easily generate a basic Swift script to find duplicate files in a user folder, replicating CleanMyMac's safe disk-cleaning engine, real-time app uninstaller daemon, and malware protection without breaking the operating system requires deep, painful systems-level debugging. Setapp as an app marketplace adds a multi-tenant billing and licensing layer that makes a full clone a serious multi-year undertaking. If you want a personal utility suite, write a few standalone Python or Swift scripts for yourself, but a true MacPaw clone is not worth the immense friction.

### What you can't replicate

- The 30-million-user ecosystem and brand trust
- Proprietary malware detection signatures and security update feeds
- The Setapp developer catalog and revenue-sharing publisher agreements

## What it does

MacPaw creates native software for macOS and iOS, including CleanMyMac, Gemini 2, and Setapp, focused on utility, optimization, and digital decluttering.

### Core features

- Low-level disk scanning and system cache cleanup
- Duplicate and similar file detection engine (Gemini 2 clone)
- App uninstaller tracking leftover system preferences and caches
- Native macOS user interface built with SwiftUI and AppKit
- Secure file encryption utility (Encrypto clone)
- App subscription license validation and local client daemon

## The business

### Pricing

- CleanMyMac Subscription: ~$39.95/yr — Annual subscription for a single Mac license.
- Setapp All-Access: $9.99/mo — Subscription marketplace unlocking over 250 curated Mac and iOS apps.

### Funding

$1.8M raised.
- Early Bootstrapped / Private Rounds
Investors: Self-funded, SMRK VC Fund connection

Founded 2008.
Team size: 400+.

## The hard parts

- Safely parsing deep system directories without violating macOS Sandbox rules or triggering System Integrity Protection (SIP)
- Writing high-performance native disk-hashing and file-scanning algorithms in Swift and C++ to minimize memory footprint
- Building a local background daemon that tracks system changes in real time for cache cleanup and app uninstallation
- Designing a secure, multi-tenant license key and subscription validation architecture similar to Setapp

## How to vibe code MacPaw

### Prerequisites

- Mac: Required to build and run native macOS applications
- Xcode (free): Official IDE and toolchain for Swift and SwiftUI development
- Node.js (free): Required for running auxiliary web-based management backend and tooling
- GitHub (free): Source code repository and version control

### Recommended AI tools

- Claude Code: Best-in-class terminal agent for scaffolding complex file structures, writing Swift scripts, and debugging system APIs
- Cursor: Ideal for fine-tuning SwiftUI views, adjusting UI polish, and reviewing code diffs manually

### Stack

- Frontend: Swift & SwiftUI (Native macOS App)
- Backend: Swift / Node.js Local Daemon
- Database: SQLite (Local storage for scan caches)
- Auth: better-auth
- Payments: Stripe
- Other: FileManager APIs, CryptoKit for Encrypto utility clone

### Hosting

- Cloudflare (Hosting personal license validation and download landing page): $0/mo

### Build guide

1. **Scaffold Native macOS Utility App** — Initialize a new native macOS project in Swift and SwiftUI using Xcode, setting up the basic navigation sidebar, window styling, and local SQLite caching layer.

```
Create a new macOS desktop application project structure using Swift and SwiftUI with a modern sidebar navigation layout. Implement a local SQLite database wrapper using SQLite.swift to store scan history and app settings locally in Application Support. Set up standard macOS window chrome, dark mode support, and clean typography matching standard Apple HIG guidelines. Ensure the app targets macOS 15+ and includes proper error handling for file system access permissions.
```

2. **Build Safe Disk Scanner & Junk Finder Engine** — Develop a recursive file scanner in Swift targeting safe user caches, logs, and temporary directories without risking system integrity files.

```
Implement a high-performance recursive directory scanner in Swift using FileManager. Traverse standard user cache paths (~/Library/Caches, ~/Library/Logs, ~/Downloads) safely. Write filtering logic to identify safe-to-delete junk files, calculate total folder sizes asynchronously using Grand Central Dispatch or Swift concurrency (async/await), and present the results in a categorized SwiftUI list with checkboxes for user selection and safe deletion.
```

3. **Build Duplicate File Finder (Gemini 2 Core)** — Implement a fast cryptographic file-hashing and similarity detection algorithm to find and purge duplicate files across selected directories.

```
Build a duplicate file finder engine in Swift. First, group files by exact byte size to eliminate non-duplicates quickly. For files matching in size, compute partial cryptographic hashes (SHA-256) of the file headers, followed by full hashes if headers match. Expose a SwiftUI view allowing users to drop a folder, view grouped duplicate files with previews, and select redundant copies for deletion while retaining at least one original.
```

4. **Build App Uninstaller & Leftover Tracker** — Create a module that lists installed applications and scans associated preference files, support folders, and application support caches.

```
Create a macOS application uninstaller module in Swift. Scan /Applications and ~/Applications for installed .app bundles. When an application is selected, parse its bundle identifier and search /Library/Preferences, ~/Library/Preferences, ~/Library/Application Support, and ~/Library/Caches for corresponding leftover files and plist entries. Display these associated files in a breakdown list before executing a clean uninstall.
```

5. **Build Encrypted File Utility (Encrypto Core)** — Implement AES-256 file encryption and decryption using Apple's CryptoKit framework for secure cross-utility file sharing.

```
Implement a secure file encryption utility in Swift using CryptoKit (AES.GCM with password-based key derivation via PBKDF2). Build a simple drag-and-drop SwiftUI interface where users can drop any file, enter a password, and output an encrypted archive file with a custom extension. Implement the corresponding decryption routine to restore the original file when the correct password is provided.
```

6. **UI Polish & Final Integration** — Refine the overall user experience with smooth animations, scan progress indicators, and comprehensive error handling for disk permissions.

```
Polish the SwiftUI user interface across all modules (System Junk, Duplicate Finder, Uninstaller, Encrypto). Add smooth progress bars, haptic-like feedback animations, summary metrics dashboards showing total space reclaimed, and clear instructions prompting users to grant Full Disk Access permissions in macOS System Settings when directory reads fail due to sandbox restrictions.
```

### Cost vs paying

**Starting costs (one-time):**

- Apple Developer Account (optional for personal local use): $99/yr
- AI Coding Tools (Claude Pro / Cursor): $20
- Total: ~$119 one-time (or $20 if sideloading locally)

**Ongoing costs (monthly):**

- Local execution hosting: $0/mo
- Total: $0/mo

- Paying for the SaaS instead: ~$9.99/mo (Setapp) or ~$40/yr
- Build time: 80-120 hours
- AI tool credits: $20 (1 month of Claude Pro / Cursor)
- Break-even: Never (purely for personal learning)
