## What it is
Rebugger is a Compose Multiplatform library that prints the reason for Jetpack Compose recompositions to the console or Logcat. It tracks changes in composable arguments and state values to explain why a recomposition occurred.

## Use cases
- debug why a composable is recomposing in Jetpack Compose
- find unnecessary recompositions causing performance issues
- track which state or argument changed between recompositions
- print recomposition reasons to Logcat during Android development
- optimize Compose UI performance by identifying unstable parameters

## When to choose
- you are developing Android or Compose Multiplatform UIs and need to diagnose recomposition behavior
- you want a lightweight drop-in composable instead of heavyweight profilers
- you need to see which specific arguments or states triggered a recomposition

## When to avoid
- you are not using Jetpack Compose or Compose Multiplatform
- you need full performance profiling rather than recomposition reason tracking
- you need a production monitoring tool rather than a development-time debugger

## Facets
- artifact type: library
- maturity: active
- function: developer-tools, logging
- domain: android-tools, developer-tools, frontend
- platform: jvm
