Rails Hackathon: Super Simple Debugging with Ruby on Rails (railshackathon.com)

Here's my Rails hackathon project from the weekend.

Checkpoint Rails records all of the critical method calls within your app, along with their important context (param/argument/return/local variable values).

You no longer need to debug with binding.pry or puts statements, as the entire call-stack for a given request is captured and presented in a consolidated timeline.

The link seems to be broken. Perhaps the repo is private?
