## What it is
Rsdoctor is a build analyzer for Rspack (and legacy webpack) projects that visualizes compilation time, loader/plugin behavior, bundle composition, and module dependencies. It includes built-in and custom rule scanning for issues like duplicate packages and bundle degradation diffing.

## Use cases
- analyze why my rspack build is slow
- visualize bundle size and module dependencies
- detect duplicate packages in my bundle
- compare bundle output between builds to find regressions
- profile loader and plugin execution time
- scan build output for anti-patterns with custom rules

## When to choose
- you build with Rspack (or Rsbuild) and need visibility into build performance and output
- you want to find bundle bloat, duplicate dependencies, or ES version issues
- you need before/after bundle diffs to prevent degradation

## When to avoid
- your project uses Vite, esbuild, or another non-Rspack/webpack bundler
- you only need a quick bundle size number without build-process analysis
- you are on webpack and cannot migrate to Rspack (1.x is maintenance-only)
