## What it is
OpenSwiftUI is an open-source reimplementation of Apple's SwiftUI declarative UI DSL in Swift, aiming to match the original API as closely as possible. It provides the API layer while other projects implement platform-specific rendering for Linux, Windows, embedded devices, and beyond.

## Use cases
- build GUI apps with SwiftUI syntax on Linux
- write SwiftUI-style interfaces for Windows
- create UIs for embedded devices like Raspberry Pi
- use declarative UI DSL outside Apple platforms
- contribute to reimplementing the SwiftUI API

## When to choose
- you want SwiftUI-style declarative UI on non-Apple platforms
- you're building embedded or Raspberry Pi UIs with Swift
- you want to contribute to an open SwiftUI implementation

## When to avoid
- you need a production-ready, complete SwiftUI API
- you're targeting Apple platforms where real SwiftUI exists
- you need mature controls like TextField, Toggle, or DatePicker

## Facets
- artifact type: framework
- maturity: experimental
- function: ui-components, frontend-framework, gui
- domain: cross-platform, developer-tools, embedded-systems
- platform: windows, cross-platform, embedded
- tags: swiftui, swift, declarative-ui, ui-dsl, apple-api-reimplementation, linux
