DevSweep is a professional CLI tool for macOS that helps developers recover disk space by safely and intelligently cleaning development tool caches.

The Problem

When you develop, you accumulate gigabytes of unnecessary caches:

Docker/OrbStack: Old images and containers (5-20GB)
JetBrains: Multiple IDE versions and corrupt caches (2-5GB per IDE)
Homebrew: Old package versions (500MB-2GB)
Node.js: npm, yarn, pnpm caches (5-15GB)
Maven/Gradle: Unused dependencies

In my case, I recovered 23GB the first time I ran DevSweep.

Features

🛡️ Safety first: Dry-run mode to preview actions before executing
🎛️ Interactive menu: Guided interface for ease of use
🔧 Modular architecture: Clean, testable and extensible code
⚠️ Explicit confirmations: Manual approval for destructive operations
📊 Smart analysis: Shows the space that will be recovered
🎨 Professional output: Organized logs with colors and progress indicators
✅ 100% tested: 101 tests, 123 assertions, all passing
🚀 Fast: Optimized to complete in seconds

Cleanup Modules

JetBrains IDEs

Removes old versions of IntelliJ, WebStorm, PyCharm, etc.
Automatically cleans corrupt caches
Intelligently preserves the latest version

Docker/OrbStack

Removes stopped containers
Cleans unused images
Removes orphan volumes

Homebrew

Cleans download caches
Removes old package versions

Dev Tools

Maven and Gradle (old dependencies)
npm, yarn, pnpm (global caches)
nvm (download caches)
SDKMan (temporary files)

System

User and system logs
Application caches
Trash

Technologies

Bash 5.0+: Modern shell scripting
Bashunit: Professional testing framework for Bash
Make: Orchestration and automation
Shellcheck: Code linting

Development with Testing

I applied TDD and clean code principles in Bash:

bash

function test_jetbrains_cleanup_removes_old_versions() {
    # Arrange
    setup_test_environment
    create_fake_jetbrains_versions "2023.1" "2023.2" "2024.1"
    
    # Act
    cleanup_jetbrains --keep-latest
    
    # Assert
    assert_directory_exists "$JETBRAINS_PATH/2024.1"
    assert_directory_not_exists "$JETBRAINS_PATH/2023.1"
}

Testing Stats:

101 tests passing
123 assertions
~11 seconds execution time
