## What it is
A webpack/rspack plugin that displays an elegant progress bar during builds and watches, with support for multiple concurrent builds and an advanced build profiler. It is customizable via custom reporters and works on Windows.

## Use cases
- show a progress bar while webpack builds my app
- profile webpack build performance
- display progress for multiple concurrent webpack builds (SSR)
- customize build progress output with custom reporters
- show build progress in CI with a minimal log reporter

## When to choose
- you use webpack or rspack and want clearer, prettier build progress output
- you run multiple concurrent builds and need per-build progress bars
- you want to profile where time is spent during bundling

## When to avoid
- you use a bundler other than webpack or rspack (e.g. Vite, esbuild, Rollup)
- you need CI dashboards or long-term build analytics rather than terminal progress output

## Facets

- maturity: active
- function: developer-tools, monitoring, logging
- domain: developer-tools, frontend, web-development
