Ruby is a dynamic object-oriented interpreted language that is open source and mixes Perl, Smalltalk, and Lisp ideas. It is compatible with various programming paradigms, including functional, object-oriented, and imperative. It also contains a dynamic system and automated memory management, making it similar to Smalltalk, Python, Perl, Lisp, Dylan, and CLU in specific ways. Ruby's primary goal is to "assist every programmer on the planet in being productive, enjoying programming, and being happy." Ruby emphasizes simplicity and efficiency.

Ruby was created by Yukihiro Matsumoto ('Matz') on February 24, 1993, and version 1.0 was published in 1996. Ruby's mindshare peaked in 2005 due to Ruby on Rails and MVC (Model, View, Controller) framework for developing web applications. However, use has continued to expand as of 2016, with Ruby gaining commercial acceptability. Therefore, 3.0.0 is the most recent stable version (2020-12-25).
