Real world applications in Ruby on Rails

I was wondering today about applications written in Ruby on Rails. What applications are out there ? I came across this list of 101 Innovative Ruby on Rails Web Apps and the “official” list of applications on rubyonrails.org.

Personally i am missing some applications in that list:

  • Lighthouse: a simple and beautiful bugtracker (SASS)
  • Redmine: another nice bugtracker
  • Typo: a blog engine (not to be confused with the TYPO3, a content management system)
  • Radiant: a CMS

I think that the most widely known app written in Rails is probably twitter.com. After an interview last year where twitter developer Alex Payne told about their issues scaling twitter there was quite a debate about the “scalability issues” of RoR. Since then there have been quite a lot of improvements in scalability and deployment of Rails apps.

Today i watched this video taken by Gregg Pollack from railsenvy.com at RailsConf 2008 where Matt Wood explained how they were able to develop an extremely high-throughput performant system for the human genome project with a lot less of spent money and time than it’s predecessor by using Ruby on Rails. I also found some slides on the web on this topic.

I think now that there are many Rails applications on the Internet i feel delighted to see that it IS possible to make thrilling and scalable real word applications in Ruby on Rails.

Keep on the rails.

Alberto.
