## What it is
Rakudo is the primary, production-ready compiler implementation of the Raku programming language, targeting the MoarVM, JVM, and JavaScript backends. It is actively maintained by the Raku Foundation and distributed under the Artistic License 2.0.

## Use cases
- compile and run Raku programs
- install a Raku interpreter on Linux, macOS, or Windows
- run Raku on the JVM or JavaScript backends
- contribute to Raku language development
- test code against the official Raku spec test suite (roast)
- build Raku from source with custom VM configuration

## When to choose
- you want the primary, most mature implementation of Raku
- you need a multi-backend compiler (MoarVM, JVM, JS)
- you want to hack on the Raku compiler or VM toolchain

## When to avoid
- you need a full Raku distribution with modules and docs preinstalled (use Rakudo Star instead)
- you only want to learn Raku without building a compiler from source

## Facets
- artifact type: cli-tool
- maturity: stable
- function: compiler, interpreter, programming-language
- domain: programming-languages, compilers, developer-tools
- platform: windows, jvm, cross-platform
- tags: raku, moarvm, nqp, perl6-family, virtual-machine-backends, compiler, linux, macos
