## What it is
An installer that provides GCC, LLVM, Clang, and developer CLI tools for OS X without requiring a full Xcode installation. It offers pre-built binary packages for older macOS versions and a script to build custom installer packages.

## Use cases
- install gcc on mac without xcode
- get command line compilers on os x
- build a custom developer tools installer package for mac
- install clang and llvm without downloading xcode
- set up a build environment on snow leopard or lion

## When to choose
- you are stuck on an old OS X version like Lion or Snow Leopard and cannot install Xcode
- you need gcc-4.2 era toolchains on legacy macOS

## When to avoid
- you use any modern macOS version - use xcode-select --install instead
- you already have Xcode installed, as mixing them causes hard-to-diagnose problems
- you need maintained, supported tooling

## Facets
- artifact type: application
- maturity: abandoned
- function: compiler, build-tool, developer-tools
- domain: developer-tools, compilers, operating-systems
- platform: cli
- tags: gcc, xcode-alternative, installer, legacy-osx, clang, llvm, macos
