Rubinius is an alternative Ruby programming language implementation created by Evan Phoenix. Based loosely on the Smalltalk-80 Blue Book design,[1] Rubinius seeks to "provide a rich, high-performance environment for running Ruby code."[2]


Rubinius follows in the Lisp and Smalltalk traditions, by natively implementing as much of Ruby as possible in Ruby code.[3]

It also has a goal of being thread-safe in order to be able to embed more than one interpreter in a single application.


From 2007 to 2013, Engine Yard funded one full-time engineer to work exclusively on Rubinius.[4] Evan Phoenix is now CEO of Vektra.[5][not in citation given]
