# JRuby

> Java-based implementation of Ruby, integrating closely with Java for two-way access.

Implementation of the Ruby programming language atop the Java Virtual Machine, written largely in Java. It is free software released under a three-way EPL/GPL/LGPL license. JRuby is tightly integrated with Java to allow the embedding of the interpreter into any Java application with full two-way access between Java and Ruby code, similar to Jython for Python.
