## What it is
NanoGUI is a minimalistic cross-platform C++/Python widget library for building GUIs rendered with OpenGL 3+, GLES 2/3, Metal, and WebGL via WebAssembly. It provides automatic layout, stateful lambda callbacks, various widgets, and full Python bindings via nanobind with PyPI wheels.

## Use cases
- build a small native GUI for a C++ graphics application
- create a Python desktop UI with OpenGL rendering
- compile a GUI app to WebAssembly for the browser
- add a settings panel to a renderer or simulation tool
- build UIs that run on Raspberry Pi via GLES2
- prototype cross-platform desktop tools with Python bindings

## When to choose
- you need a lightweight, minimal GUI tied to OpenGL/Metal rendering
- you want one codebase targeting desktop, ARM, and the browser via Emscripten
- you want Python bindings for a C++ widget library

## When to avoid
- you need a full-featured application framework with extensive widgets
- you want GPU-agnostic UI without OpenGL/Metal dependencies
- you need a declarative or web-based UI toolkit

## Facets
- artifact type: library
- maturity: active
- function: ui-components, graphics, gui
- domain: cross-platform, web-development, graphics, developer-tools
- platform: cpp, python, windows, wasm, browser
- tags: opengl, metal, webgl, gles, nanovg, widget-library, python-bindings, retina, hdr, macos, linux, ios
