## What it is
Appyx is a model-driven navigation library with UI components for Jetpack Compose and Compose Multiplatform. It lets developers define custom navigation models with type-safe, testable navigation state and gesture-driven transitions animated via Compose Modifiers.

## Use cases
- navigate between screens in a Jetpack Compose app
- build custom back stack or card stack navigation with gestures
- make navigation state unit-testable in a Compose app
- create swipeable view pager transitions in Compose Multiplatform
- implement type-safe navigation without boilerplate
- animate screen transitions with custom Compose Modifiers

## When to choose
- you use Jetpack Compose or Compose Multiplatform and want full control over navigation state and transitions
- you need gesture-driven or custom navigation models beyond simple screen-to-screen routing
- you want testable, model-driven navigation in a Kotlin Multiplatform project

## When to avoid
- you need a simple, conventional navigation solution with minimal setup
- your project does not use Jetpack Compose
- you rely on platform-standard navigation components or need extensive third-party ecosystem support

## Facets
- artifact type: library
- maturity: active
