## What it is
Bundle Buddy is a tool that helps developers understand their JavaScript bundle size and why specific files end up in their bundles. It analyzes source maps to visualize code duplication and inform code-splitting decisions.

## Use cases
- analyze why a file is included in my javascript bundle
- find duplicate code across webpack bundles
- reduce javascript bundle size
- visualize bundle composition from source maps
- decide what code to split into separate chunks
- debug bloated production bundles

## When to choose
- you ship JavaScript bundles and want to understand their composition
- you need to identify duplicated modules across multiple bundles
- you are planning code-splitting and want data on shared code

## When to avoid
- you need a maintained tool with active development and support
- you want runtime performance profiling rather than static bundle analysis
- you need bundler-agnostic support beyond source-map-based workflows

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: developer-tools, build-tool, data-visualization
- domain: developer-tools, web-development, frontend, performance
- platform: cli
- tags: bundle-analysis, code-splitting, javascript-bundles, webpack, source-maps, nodejs, web-server
