The 1.1 version of RailsAssistant for Mac was provided as a free download on our website. This Mac app was originally developed by Nocturnal Code Ltd. The software lies within Developer Tools, more precisely General.
From the developer:
RailsAssistant can run your Rails project, bundle your Gemfile, automatically run your unit tests and it generally helps you develop Rails apps faster. Getting your project up and running is easy with Rails Assistant. Just drop it in. Want to run a Rack App? You can! Rails Assistant knows how to run Rack-compatible servers and more.
