## What it is
Epoxy is an Android library from Airbnb for building complex RecyclerView screens with multiple view types. It generates models from custom views or databinding layouts via annotation processing and handles view holders, diffing, item ids, and state saving automatically.

## Use cases
- build complex recyclerview screens with multiple view types
- reduce recyclerview adapter boilerplate in android apps
- automatically diff and update list items
- create carousels and mixed-content lists
- save recyclerview view state across configuration changes
- generate epoxy models from custom views or databinding layouts

## When to choose
- building Android screens with heterogeneous list content like headers, carousels, and loading rows
- you want declarative, composable RecyclerView adapters without manual view holder code
- your team uses Kotlin or Java with Gradle and wants annotation-generated models

## When to avoid
- building a Jetpack Compose app where RecyclerView is not used
- you only need a simple single-view-type list
- your project does not target Android

## Facets
- artifact type: library
- maturity: stable
- function: ui-components, state-management
- domain: mobile-development, android-tools, frontend
- platform: -
- tags: recyclerview, android-ui, annotation-processing, diffing, jetpack-compose-alternative, kotlin, android
