This branch of delayed_job works pretty well. It's really easy to implement if you're already using delayed_job in your app.

Edit: This gem should work in Rails 3 according to this S.O thread.

Personally, I am not sure but I updated the answer with one that should work in Rails 3. – JackCA Jan 13 '11 at 00:24
Note that Workless works on Cedar, while I don't believe the HireFire gem does. – Becca Royal-Gordon May 20 '12 at 04:04
I've tried [Workless](https://github.com/lostboy/workless). So far, so good. Works out of the box, with about zero config, and it's free. Very pleased, thanks for the recommendation. – mjnissim Feb 22 '13 at 14:56

You could adapt this gem to detect when there's a lot of jobs and then scale it up.

There is also guv which is open source. If you don't want to run it yourself, you can also use it as an add-on

I am using workless gem, and it seems reliable for my dev purpose (scale between 0 and 1 worker) I tried to use heroscale.com but the service is down for 2 month and I am not that confident with leaving my heroku credentials on such a young service

There are a few options. Heroku exposes the Platform API which you can use to scale up and down. Alternatively, there are a few Heroku Addons that can solve this problem for you. I use this heroku autoscaling addon for my projects.

HireFire is a great gem for 'scaling' workers- allows you to only pay for the exact amount (to the second) of work that needs to be done. Works with delayed job and rescue.
