If you’ve ever wondered, “Why is my composable recomposing so many times?” — you’re not alone

Jetpack Compose makes UI building elegant, but understanding when and why recomposition happens can get tricky.

Recently, I came across an awesome open-source library Rebugger — and it’s a total game-changer!

What Rebugger Does

Rebugger helps you visualise recompositions in real-time by showing which parameters triggered a recomposition and how often it happens — right inside your UI or logcat.

No need to guess anymore — you see exactly what changed and why Compose decided to recompose.

How to Use

Just wrap your composable with the Rebugger composable, providing the variables you want to track in the trackMap:

Rebugger(trackMap = mapOf(
    "state" to statekot, // Replace with your actual state/variable
    "user" to user,       // Replace with your actual state/variable
    "products" to products // Replace with your actual state/variable
)) {
    // Your Composable Content goes here
}
