Introduction
Getting started with Judoscale
Get your dynos autoscaling for free in less than 5 minutes. Ready? Go!
Provision the Add-On
Before we do any gem installs or code-changes, let's provision the add-on for our Heroku app! We can either do that via the Heroku CLI with:
heroku addons:create judoscale -a YOUR_APP_NAME
or via the web UI:

By default this will provision our free White Belt plan, which includes 20 autoscales per month and all autoscaling features. This is the best way to try Judoscale before upgrading to a paid plan for a production application.
Once provisioned by Heroku, launch Judoscale via the CLI or by clicking the link in Heroku's web UI:
heroku addons:open judoscale -a YOUR_APP_NAME
Judoscale will walk you through installing an adapter specific to your application language and framework. See below for the web frameworks and job backends we currently support:
- Web Processes
- Ruby: Rails, anything Rack-based
- NodeJS: Express
- Python: Django, Flask
- Background Job Processes
- Ruby: Sidekiq, Resque, DelayedJob, Que in Rails or Rack-based
Once you've got the Judoscale packages installed, you'll just need to check out the Judoscale app dashboard and change any default scaling configuration parameter's you'd like!
