Emulating Heroku on local computer

Question

I'm new to Heroku and Ruby on Rails and this may seem trivial. But I could not find the answer.

The Google App Engine has a web server application that emulates all of the App Engine services on local computer. Does Heroku have something similar?

Basically I want to run/debug RoR app on local machine before pushing it to Heroku.

If you are on the Cedar stack, there is a local utility called foreman that can read your procfile to simulate how it will run on Heroku. More info about it is on Dev Center here:
