## What it is
Nana is a modern C++ GUI library with a standard-like API for building cross-platform desktop applications. It is regularly tested on Linux (X11) and Windows, with experimental support for macOS and FreeBSD.

## Use cases
- build a cross-platform desktop GUI application in C++
- create native windows and forms with modern C++ style
- develop a lightweight C++ GUI without heavy framework dependencies
- write a desktop app that runs on both Linux and Windows
- learn a C++ standard-like GUI toolkit
- prototype a small desktop tool with a graphical interface

## When to choose
- you want a header-friendly, modern C++ (C++11/14/17) GUI toolkit
- you need cross-platform desktop apps on Linux and Windows
- you prefer a Boost-style license and a standard-library-like API
- you want a lightweight GUI library without large runtime dependencies

## When to avoid
- you need first-class macOS support (still experimental)
- you require a very large ecosystem, rich widget set, or commercial-grade tooling like Qt
- you need mobile or web deployment
- you want long-term guaranteed maintenance cadence

## Facets
- artifact type: library
- maturity: active
- function: gui, ui-components
- domain: desktop-applications, cross-platform, web-development
- platform: windows, bsd, cross-platform, cpp
- tags: gui-toolkit, modern-cpp, c-plus-plus-11, c-plus-plus-14, c-plus-plus-17, template-metaprogramming, x11, windowing, linux, macos
