This does actually work, however be warned this will incur costs on your heroku account.

EDIT: False alarm, Heroku billing has changed so the application did not fall into my free dyno range.

You get the same 750 hours free usage as all other apps.

Following the steps in that gist, I have a heroku clojure app up that just created an invoice line item for 1 worker. It was only for a few minutes, but I definitely just got charged for it.


On June 1, 2011, Heroku switched from billing for “dynos” to billing for “dyno-hours”, which is more clear. This brings pricing inline with the new process model, wherein you can run one-off processes as well as manipulate the dynos for each of your app’s process types independently.

The vast majority of apps will see a 1% - 10% reduction in overall monthly dyno charges. Previously, Heroku included “1 free dyno” with each app, which is equivalent to between 672 and 744 dyno-hours (depending on the length of the month). With this switch to dyno-hours, we are converting the included free dyno to a fixed 750 free dyno-hours. This makes more sense, is more consistent, gives all users additional free dyno-hours, and allows the free dyno-hours to be used for any kind of process (web, workers, one-off admin process, or any other Procfile process).

Ahhhh that would be why, I didn't notice the 'future' billing change that is supposed to happen tomorrow.

I'll edit my original post to clarify.

On a more serious note, thanks for the great work Heroku! Very excited to see you guys turning into a generic service platform with a strong API based addon presence.

To the tune of probably 1 or 2 cents. Not saying it shouldn't be mentioned, but let's not scare people away here.

So there is official support for Ruby and Node.js, and inofficial support for Clojure?

Are there any other languages that are supported inofficially?

It looks like Python is also working:

There's Logo, which is documented on their site [1], but it was an April Fool's Day joke so I don't know if it's officially supported.
