## What it is
Parceler is a Java annotation processor that generates Android Parcelable boilerplate code for POJOs annotated with @Parcel. It eliminates manual implementation of writeToParcel, createFromParcel, and CREATOR, providing a Parcels utility for wrapping and unwrapping objects.

## Use cases
- generate Android Parcelable implementations from POJOs
- remove Parcelable boilerplate from Android apps
- serialize objects between Android activities via Bundles
- wrap and unwrap objects with Parcels utility
- avoid reflection-based serialization on Android

## When to choose
- you write Android apps in Java and want Parcelable support without boilerplate
- you prefer compile-time code generation over runtime reflection
- you need fast Parcelable serialization between Android components

## When to avoid
- your project is pure JVM or server-side Java with no Android dependency
- you already use Kotlin with @Parcelize or kotlinx.serialization
- you rely heavily on private-field serialization and cannot accept reflection overhead

## Facets
- artifact type: library
- maturity: stable
- function: serialization, boilerplate, sdk
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: annotation-processor, parcelable, code-generation, android
