## What it is
A webpack plugin that measures and reports the time spent in each loader and plugin during webpack builds. It wraps your webpack config and prints human-readable or JSON timing output to help identify build bottlenecks.

## Use cases
- measure webpack build speed
- find slow webpack loaders
- profile webpack plugin performance
- optimise webpack build times
- output build timing as
- opt-in build measurement via environment variable

## When to choose
- you use webpack and want to know which loaders or plugins slow your build
- you need per-loader and per-plugin timing breakdowns
- you want machine-readable build timing data for CI or tooling

## When to avoid
- you use a bundler other than webpack such as Vite, esbuild, or Rollup
- you need runtime application performance profiling rather than build-time profiling

## Facets
- artifact type: plugin
- maturity: active
- function: monitoring, benchmarking, build-tool
- domain: developer-tools, web-development, performance, frontend
- platform: cli
- tags: webpack, build-performance, profiling, loaders, timing, nodejs
