Frequently Asked Questions

Is NPM Package Analyzer free?

Yes, PivaBox NPM Package Analyzer is completely free to use. There are no charges, subscriptions, or hidden fees. All analysis runs locally in your browser.

Is my package.json uploaded to a server?

No. All parsing and analysis happens entirely in your browser using JavaScript. Your package.json content — including dependency names, versions, and scripts — never leaves your device.

How accurate is the version check?

The tool compares dependency versions against hardcoded latest versions for about 70 commonly used npm packages (React, Vue, Next.js, Express, TypeScript, etc.). Dependencies not in this reference list show a "?" status. For comprehensive version checking, run <code>npm outdated</code> in your project directory. The security score and bundle size estimate are heuristic-based and should be used as general guidance, not definitive metrics.
