Because New Relic RPM is used by more than 4,000 organizations to manage their Ruby on Rails and Java applications in production, we have unique insight into how thousands of applications are deployed.
Since April, 2009, we have periodically published on RailsLab a summary of the most commonly used versions of Ruby, Rails and the various plugins and gems deployed for Ruby applications. This report enables you to compare your own deployed application stack with those used by other development teams. Are you behind the curve in Ruby? Are there some plugins or gems that your team may want to consider? Have you developed a gem and wonder how many apps use it in production? This is a good place to start that conversation.
