Introducing Package Scout: A WebAssembly-Powered Package Analysis Tool
In the ever-evolving landscape of modern web development, having quick and reliable insights into package characteristics is invaluable. To address this need, I am excited to introduce Package Scout, a browser-based package analysis tool designed to streamline the evaluation of npm packages directly within your browser environment.
What is Package Scout?
Built using cutting-edge web technologies, Package Scout leverages WebAssembly (WASM) and contemporary web APIs to provide a comprehensive overview of npm packages without the need for any local setup. Users can analyze various aspects of a package, including:
- Bundle sizes and module footprint
- Dependency trees and relationships
- Module types and formats
- Additional package metadata
This tool aims to empower developers with instant, in-browser insights, aiding in dependency decision-making and optimization efforts.
Live Demonstration and Access

Open Source and Community Involvement
The source code for Package Scout is openly available on GitHub: https://github.com/package-scout/package-scout. Contributions, feedback, and suggestions are highly welcomed as the project continues to evolve. Whether you’re interested in improving functionalities, fixing bugs, or enhancing the interface, your involvement can make a meaningful difference.
Inspiration and Motivation
This project draws inspiration from bundlephobia, a well-regarded tool that many in the frontend community rely on for assessing package sizes. Personally, bundlephobia has been a staple in my development toolkit—especially during a previous role that involved refactoring a large frontend codebase and seeking lightweight dependencies. Over the years, it has become a standard reference point for optimizing web bundle sizes, often adorned with badges that reflect package health and efficiency.
Unfortunately, recent issues with bundlephobia’s availability have prompted me to develop an alternative. Package Scout aims to fill this gap by providing a robust, browser-based solution that remains accessible even when external tools face disruptions.
Future Outlook
While Package Scout is still under active development, there’s a lot more to add—such as deeper dependency analysis, real-time updates, and enhanced visualization. I invite developers and enthusiasts to share their
