BundleBuddy

BundleBuddy helps you analyze the JavaScript resources running on any webpage by identifying and grouping all loaded bundles—both from the DOM and network performance—and visually highlighting possible duplications.

Easily discover which scripts might be unnecessarily loaded multiple times, causing performance issues or conflicts. BundleBuddy marks these duplicates clearly in the scan results, allowing developers to optimize script loading and reduce redundancy.

Whether you're debugging a messy site or just curious about what's under the hood, BundleBuddy gives you clarity and control over your JS resources.

Supports grouping by domain, localized interface (English, Spanish, French), and clear visual cues for duplication.
