npm Package Dependency Analyzer

This tool analyzes your package.json file and provides insights into your project's dependency tree. It categorizes packages by type (production vs dev), analyzes version range patterns, estimates bundle size contribution, and groups dependencies by category (framework, utility, testing, build tools, etc.).

Understanding your dependencies helps you identify unused packages, detect outdated version patterns, and make informed decisions about bundle size optimization. All analysis happens in your browser — no data is uploaded to any server.

1. Copy your package.json — Open your project's package.json file and copy the entire contents to your clipboard.
2. Paste into the input area — Paste the JSON content into the text area. You can also click "Example package.json" to see a sample analysis.
3. Click Analyze — The tool parses your dependencies and generates an analysis with statistics, charts, and a detailed table.
4. Review Insights — Check the summary cards for totals, the version range distribution for update patterns, and the dependency table for individual package details.
