How many ruby framework available in market?

Hi all,
I wanna know how many ruby framework available in the market as of
now and using them any company created any website or not.
I searched on net but did not find the appropiate answer.
Some which i know:

  1. ROR
  2. IronRuby
  3. JRuby

These three only but don’t know any site name which has been created
using IronRuby or JRuby.

Please help me out.

Thanks

I think your slightly mixed up. JRuby, IronRuby, MRI (the standard C
implementation), Rubinius etc… are implementations of the ruby
language itself. RoR is just a bunch of libraries on top of that.
IronRuby is still a long way from being finished, so I would be very
surprised if people were using it in production. Just off the top of
my head, I know that mingle (by thoughtworks) and oracle mix run on
jruby.
