===Historical implementations===
[[Pugs (compiler)|Pugs]] was an initial implementation of Perl 6 written in [[Haskell]], led by [[Audrey Tang]]. Pugs used to be the most advanced implementation of Perl 6, but since mid 2007, it is mostly dormant (with updates made only to track the current version of the [[Glasgow Haskell Compiler]] (GHC)). As of November 2014, Pugs was not being maintained.<ref>{{cite web|url=http://perl6.org/compilers/features|title=Feature comparison of Perl 6 compilers|archive-url=https://web.archive.org/web/20190207035658/https://perl6.org/compilers/features|archive-date=7 February 2019|url-status=dead}}</ref>

In 2007, v6-MiniPerl6 ("mp6") and its reimplementation, v6-KindaPerl6 ("kp6") were written as a means to bootstrap the Perl-6.0.0 STD, using Perl 5. The STD is a full grammar for Perl 6 and is written in Perl 6. In theory, anything capable of parsing the STD and generating executable code is a suitable bootstrapping system for Perl 6. kp6 is currently compiled by mp6 and can work with multiple backends.<ref name="STD">{{cite web |url=https://github.com/perl6/std/blob/master/STD.pm6 |title=Perl 6 STD |last1=Wall |first1=Larry |author1-link=Larry Wall| website=[[GitHub]] |year=2007|display-authors=etal}}</ref><ref>{{cite web |url=http://darcs.pugscode.org/v6/v6-KindaPerl6/docs/FAQ.pod |title=mp6/kp6 FAQ |year=2006 |publisher=Perl 6 development team}}</ref> mp6 and kp6 are not full Perl 6 implementations and are designed only to implement the minimum featureset required to bootstrap a full Perl 6 compiler.

Yapsi was a Perl 6 compiler and runtime written in Perl 6. As a result, it required an existing Perl 6 interpreter, such as one of the Rakudo Star releases, to run.<ref>{{cite web |url=https://github.com/masak/yapsi/blob/master/README |title=Yapsi README |website=[[GitHub]] |year=2011}}</ref>

Niecza, another major Perl 6 implementation effort, focused on optimization and efficient implementation research. It targets the [[Common Language Infrastructure]].<ref name="nieczareadme">{{cite web
