## What it is
A Webpack plugin from GoogleChromeLabs that prints the gzipped sizes of your webpack assets and the changes since the last build. It tracks bundle sizes over time to help enforce performance budgets.

## Use cases
- track webpack bundle sizes over builds
- show gzip size changes in build output
- enforce performance budgets on javascript bundles
- detect bundle size regressions in ci
- monitor gzipped asset sizes across releases

## When to choose
- you use webpack and want visibility into bundle size changes between builds
- you want to catch size regressions before shipping
- you need gzipped size reporting in your build pipeline

## When to avoid
- you use rollup or vite instead of webpack (use rollup-plugin-size or similar)
- you need full bundle analysis with visualizations (use webpack-bundle-analyzer)
- your project does not use a bundler

## Facets
- artifact type: plugin
- maturity: maintenance
- function: build-tool, monitoring, benchmarking
- domain: developer-tools, web-development, frontend, performance
- platform: cli
- tags: webpack-plugin, bundle-size, gzip, performance-budget, nodejs
