A platform and ecosystemfor Developers to:• Freely host open source

projects and code• Connect, Communicate,

Collaborate, and Code with peers

• Eventually easily deploy applications/services to “clouds”

Endorsements

Look like the best deploying option I ever

found for Rails, GREAT!

the easiest rails stack in the world, jruby 1.2rc, rails 2.3rc,

glassfish v3...

too easy to run jruby/rack/glassfish behind nginx

leading the way to simple, scalable, no-hassle hosting for

Ruby web applications....

it's true one-step deployment.

had no reliability and performance issues with

Glassfish

money is on JRuby (and Glassfish) for the long haul; if you haven't checked

out Glassfish yet, you're doing yourself a disservice!nice way to deploy and

manage my app while leaving things open for scaling
