Ruby here is the main language of the repository. Plugins and extensions for this software are usually written in Ruby and distributed as gems. A record carries this value when Ruby makes up most of the codebase, as stated by the project or shown by its repository. Running it needs Ruby installed, on the server for applications built with it and on the build machine for site generators. Ruby on Rails and Jekyll are examples.

What is the best web software written in Ruby?
We can't tell from here. What suits an editor-heavy marketing site can be wrong for a static documentation site. The list is alphabetical and nobody paid for a place on it.
