Stop wasting time on dead code. Start shipping faster, cleaner applications today.

Transform your codebase from cluttered to clean in minutes. Dead Code Checker automatically finds and eliminates unused functions and variables, reducing bundle sizes by up to 30% and making your code instantly more maintainable.

Every day, developers waste 2-3 hours navigating through unused code that:

• 📈 Increases bundle sizes - slowing down your apps
• 🧠 Creates cognitive overload - making code reviews painful
• 🐛 Hides real bugs - in a sea of unused functions
• ⏱️ Slows down refactoring - fear of breaking "mystery" code
• 💸 Costs money - in CI/CD time and deployment overhead

The solution? Automated dead code detection that works in seconds, not hours.

# One command to rule them all
npx dead-code-checker -f ./src

With Real-Time Progress Tracking:

🔍 Analyzing codebase...

• 1,058/1,247 - Current/Total files processed
• 📖 Reading files - Current stage (Collecting → Reading → Processing → Analyzing)
• 📄 filename.tsx - Currently processing file

🎯 Instant Results:

• Find all unused functions and variables
• Get exact file locations and line numbers
• Remove dead code with confidence
• Reduce bundle size immediately
• NEW: Real-time progress tracking with current file display

❌ Before: 847 KB bundle size, 2,341 unused variables
✅ After:  592 KB bundle size, 0 unused code (-30% size!)

# No installation needed - scan any project immediately
npx dead-code-checker -f ./src

# See results instantly:
✅ Found 23 unused functions in 12 files
📁 src/utils/helpers.ts:45 - function calculateOldMetric
📁 src/components/OldButton.tsx:12 - const unusedVariable

# Install globally for repeated use
npm install -g dead-code-checker

# Or add to your project
npm install dead-code-checker --save-dev

# Ignore specific functions/variables
dead-code-checker -f ./src -in "debugFunction,testVariable"

# Ignore entire folders  
dead-code-checker -f ./src -if "tests,__mocks__"

# CI/CD mode (fails on dead code)
dead-code-checker --ci -f ./src

# Quiet mode (minimal output)
dead-code-checker --quiet -f ./src

# Disable progress bar
dead-code-checker --no-progress -f ./src

Prevent dead code from ever reaching production:

# GitHub Actions Example
name: Dead Code Check
on: [push, pull_request]

jobs:
  dead-code-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'
      - name: Check for dead code
        run: npx dead-code-checker --ci -f ./src

Build custom workflows and integrations:

const DeadCodeChecker = require('dead-code-checker');

const checker = new DeadCodeChecker('src/', {
  ignoreNames: ['debugUtils', 'testHelpers'],
  ignoreFolders: ['tests', '__mocks__']
});

checker.run();
const report = checker.getReport();

// Custom reporting, Slack notifications, etc.
console.log(`Found ${report.deadCode.length} issues`);

For a team of 5 developers:

• Time saved per week: 10 hours (dead code navigation)
• Bundle size reduction: 20-30% average
• Faster builds: 15-25% improvement
• Yearly value: $50,000+ in developer productivity

Start saving time today - it's free and takes 30 seconds.

Clean projects feel different:

✅ No dead code found! Your codebase is clean and optimized.

Found issues? No problem:
