## What it is
A Webpack plugin and browser-based site that visualizes Webpack bundle contents as a treemap, showing which modules take up space and which may be duplicates. It can be used by uploading a stats JSON file to the hosted site (data stays in the browser) or by adding the plugin to a Webpack config to emit a stats.html file.

## Use cases
- analyze which modules are bloating my webpack bundle
- find duplicate modules in a webpack build
- visualize bundle size breakdown as a treemap
- generate a stats.html report from webpack build
- see what's taking up space in my javascript bundle
- inspect webpack stats  offline in the browser

## When to choose
- you use Webpack and want a quick visual breakdown of bundle composition
- you want a client-side tool that never uploads your stats data
- you want an automated stats.html artifact generated on each build

## When to avoid
- you use a modern bundler like Vite, Rollup, or esbuild instead of Webpack
- you need actively maintained tooling with recent feature development
- you need CI-friendly machine-readable bundle reports rather than a visual treemap

## Facets
- artifact type: plugin
- maturity: maintenance
- function: data-visualization, developer-tools, build-tool
- domain: developer-tools, web-development, frontend, analytics
- platform: cli
- tags: webpack, bundle-analysis, visualization, treemap, javascript, nodejs, web
