Why Use Bundle Size Analyzer?

You should try Bundle Size Analyzer for a quick, private way to budget your js bundle size. All processing happens in your browser. Your files and data never leave your device. According to web.dev, client-side processing is the gold standard for privacy.

On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
