Open source website bundle analyzer that shows vulnerable NPM packages

I’d like to share an open source project I’ve been working on during the last year. It analyzes production JavaScript code and detects bundled NPM package versions. A vulnerability is shown when a specific detected version contains known vulnerabilities, taken from the Github advisory.

There’s also a dedicated package page, that shows accumulated statistics of a package. It’s like wappalyzer or builtwith but with better accuracy. For example: https://gradejs.com/package/react

So far I’ve only indexed ~10,000 popular websites. The current version works for Webpack bundles with 70-90% accuracy and ~3% false positive. The package detection algorithm is designed to match minified and tree-shaken AST subtrees for each export per bundled JS module.

I'd like to collect any feedback from the community.
