## What it is
GLEW (The OpenGL Extension Wrangler Library) is a cross-platform C/C++ library for loading and querying OpenGL extensions at runtime. It exposes OpenGL core and extension functions through a single header file and includes utility tools like glewinfo and visualinfo.

## Use cases
- load OpenGL extension functions at runtime in a C++ application
- query which OpenGL extensions the target GPU supports
- write cross-platform OpenGL code with a single extension header
- check OpenGL capabilities on Windows, Linux, and macOS
- use EGL, GLX, or WGL context extension entry points
- generate a report of supported OpenGL features with glewinfo

## When to choose
- you are writing a C/C++ OpenGL application and need extension loading
- you want a mature, widely supported, single-header OpenGL loader
- you need to support legacy OpenGL versions and multiple windowing systems (WGL, GLX, EGL)

## When to avoid
- you are targeting modern OpenGL/Vulkan only and prefer a lighter loader like glad
- you are doing WebGL or browser-based graphics where extension loading is handled for you
- you need a full rendering or game engine rather than an extension loader

## Facets
- artifact type: library
