## What it is
Rubinius is a language platform and virtual machine that supports multiple programming languages, best known as an alternative implementation of Ruby. It is written primarily in C/C++ and runs on macOS and Unix/Linux systems.

## Use cases
- run Ruby code on an alternative virtual machine
- study how a language VM and JIT compiler are built
- experiment with implementing new programming languages on a shared runtime
- benchmark Ruby implementations against MRI
- contribute to an open-source Ruby interpreter

## When to choose
- you need an alternative Ruby implementation for research or compatibility testing
- you want to learn VM internals from a mature codebase
- you're targeting Unix/macOS environments only

## When to avoid
- you need Windows support
- you need production Ruby with the broadest gem compatibility - MRI is safer
- you need actively developed cutting-edge Ruby features

## Facets
- artifact type: application
- maturity: maintenance
- function: interpreter, compiler, programming-language
- domain: programming-languages, compilers, developer-tools
- platform: cpp, c
- tags: ruby, virtual-machine, language-platform, jit, linux, macos
