MoarVM (Metamodel On A Runtime Virtual Machine) is a virtual machine built for the 6model object system. It is being built to serve as yet another VM backend for NQP (Not Quite Perl) and Perl 6.[3] MoarVM was created to allow for greater efficiency than Parrot by having a closer internal representation to the model system used by Perl 6[4]. Notably it was the virtual machine for the first stable version of Perl 6 Rakudo released in December 2015[5][6].

Work began on MoarVM on March 31, 2012; the project was first publicly announced the following year on May 31, 2013.

As of March 2014, it is the fastest virtual machine for Rakudo and NQP (Not Quite Perl) in terms of startup time and build speed.[7]

MoarVM is available under the Artistic License 2.0.[8]
