## What it is
GacUI is a GPU-accelerated cross-platform C++ GUI library with built-in MVVM, data binding, and XML-based UI description using the Workflow script language. It supports Windows, Linux, macOS, and HTML5 rendering, with code generation to C++ for static linking.

## Use cases
- build a cross-platform desktop app in c++
- gpu accelerated gui framework for c++
- mvvm ui library with data binding in c++
- describe ui in xml and compile to c++
- render ui in a browser via html5
- multi-language gui application in c++

## When to choose
- you want a full-featured retained-mode GUI framework in pure C++
- you need MVVM and data binding without extra dependencies
- you target Windows primarily but want Linux/macOS/HTML5 options
- you prefer XML-defined UI compiled to optimized C++ source

## When to avoid
- you need a lightweight immediate-mode GUI like ImGui
- you require a permissive license - licensing is custom and must be reviewed
- you want broad ecosystem and package-manager integration
- you need mobile platform support

## Facets
