Client Gem for Subscribers

Scale your Heroku app's dynos according to demand.

Rack middleware sits on top of all requests and watches the number of Dynos in use and the number of pending requests. Depending on the settings entered at JSON reports are posted over to the server. The server then calculates the needed adjustments and handles all communications with Heroku.

See for more information.
