## What it is
Redwood is a Kotlin Multiplatform library for building reactive user interfaces for Android, iOS, and web using Jetpack Compose-style composable functions. It lets developers define UIs from a shared schema and render them with platform-native widgets, Compose UI, or the browser DOM.

## Use cases
- build a shared reactive UI in Kotlin for Android and iOS
- render the same composable UI to native views, Compose, and the web DOM
- define a UI widget schema and generate multiplatform code from it
- share business logic and UI tree construction across platforms with Kotlin
- build server-driven or Treehouse-style UIs rendered remotely and displayed natively

## When to choose
- you are already invested in Redwood or maintaining an existing app built on it
- you want a Compose-based shared UI rendered with platform-native widgets on Android, iOS, and web

## When to avoid
- starting a new project, since the project is no longer under active development
- you need long-term support, bug fixes, or an active community
- you only target a single platform where native frameworks like Jetpack Compose or SwiftUI suffice

## Facets
- artifact type: library
- maturity: abandoned
- function: frontend-framework, ui-components, state-management
- domain: mobile-development, web-development, frontend, cross-platform
- platform: jvm, browser
- tags: kotlin-multiplatform, jetpack-compose, reactive-ui, schema-driven-ui, discontinued, android, ios, web-server
