Hi! 🖐
I'm Sergey Melyukov and I'm a maintainer of Statoscope.

Statoscope is a modern tooklit for analyzing and validating your bundle.
You can try Statoscope by simply dropping the stats of your build into https://statoscope.tech or using a webpack plugin that will generate a UI-based report about your build.
This report will show you full information about your build, NPM packages duplicates, and even the download speed of your bundle to a client browser. With this UI report, you can make your own requests to stats and generate your own reports about your bundle. This is very similar to python notebook, but for webpack stats and is possible thanks to a special query language.

Also, Statoscope is able to validate your build on CI, there is a special CLI tool for this. You can make sure that, for example, the time of building your bundle or loading the bundle to a client browser does not exceed the limit you have defined.

Also, there are many plans to improve Statoscope features.
