Is there any debug toolbar for Rails 3.x

Question

I used Rack::Bug more than one year ago, now I'd like to use it with a new Rails 3.1 project. I tried to install it, both the master and rails3 branches, but with no luck.

Also tried some github forks but they did not work either.

Is there any alternative with the same features?

P.S. I already know newrelic and its developer mode, just looking for something else, more similar to Rack::Bug

Here is a little screen shoot of what is capable of (the green toolbar with debugging informations)

Answer 1

Rack bug seems to e fixed, rails3 branch works for me on 3.1.1
