Can CleanMyMac be vibe coded?
Surface large files, caches, login items, and safe cleanup suggestions without deleting automaticall
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For CleanMyMac, surface large files, caches, login items, and safe cleanup suggestions without deleting automatically. The hard boundary is os-specific cleanup knowledge, malware scanning, updater integrations, and support, plus os integration polish and maintenance.

The achievable core
- Provide one focused macOS utility that surfaces large files, caches, login items, and safe cleanup suggestions without deleting automatically, exposes keyboard-first controls, and stores settings locally.
- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- OS-specific cleanup knowledge, malware scanning, updater integrations, and support
- years of OS-version edge cases
- large extension ecosystem
- cross-device sync
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
Why people still pay
People still pay for CleanMyMac because small utilities are technically reproducible, but customers pay for polish and immediate fixes when an OS update breaks a daily habit. The recurring cost buys permissions, accessibility APIs, sandboxing, signing, notarization, OS regressions, updates, backups, and support, not just the visible interface.

Build brief — a focused alternative to CleanMyMac
Context
**CleanMyMac** — Surface large files, caches, login items, and safe cleanup suggestions without deleting automaticall. It currently costs $3.33/mo.
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For CleanMyMac, surface large files, caches, login items, and safe cleanup suggestions without deleting automatically. The hard boundary is os-specific cleanup knowledge, malware scanning, updater integrations, and support, plus os integration polish and maintenance.
This brief describes a focused, single-operator replacement for the part of CleanMyMac that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Provide one focused macOS utility that surfaces large files, caches, login items, and safe cleanup suggestions without deleting automatically, exposes keyboard-first controls, and stores settings locally.
Build a focused single-user workflow with real persistence, search, and export.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
MacOS 14 or later.
Xcode.
Only the permissions required by the selected feature.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a personal replacement for CleanMyMac in an empty repository.
Use Swift 6, SwiftUI, AppKit where necessary, SQLite, and the macOS Keychain; do not offer alternative stacks.
The core loop is: provide one focused macOS utility that surfaces large files, caches, login items, and safe cleanup suggestions without deleting automatically, exposes keyboard-first controls, and stores settings locally.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create a menu-bar app with a searchable command window and global hotkey.
Implement only the primary feature and one settings screen instead of a plugin platform.
Request permissions just in time and explain why each is needed before opening System Settings.
Store configuration locally, support export or import, and never capture unrelated user content.
Add launch-at-login, update-check opt-in, diagnostics export, and a complete uninstall note.
Write unit tests for transformation logic and one UI test for the core keyboard workflow.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out a third-party extension marketplace.
Deliberately leave out cloud accounts and cross-device sync.
Deliberately leave out broad automation that executes untrusted scripts.
Finish by running the tests and listing the exact commands used.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
OS-specific cleanup knowledge, malware scanning, updater integrations, and support.
Years of OS-version edge cases.
Large extension ecosystem.
Cross-device sync.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
What you still own after launch
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Risk
**Manageable.** A personal version is realistic if you test the critical journey and keep reliable backups.
Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.
