We’ve been working with Heroku to bring you an even easier and more convenient way to add Hoptoad to your Heroku apps:
$ heroku addons:add hoptoad:plus
$ heroku addons:add hoptoad:basic
Or, if you prefer, you can add Hoptoad to your app with a single click over on the Hoptoad Heroku Addon page.
Once you’ve configured the addon, you’ll want to install the Hoptoad Notifier in your project, and you can use a shiny, new, Heroku-specific configuration flag in the generator:
$ rails generate hoptoad --heroku
Then, you can click through from your Heroku dashboard to the Hoptoad addon, and get the same Hoptoad interface you’re come to know and love:


I would highly recommend building your own Heroku addon. The experience is getting very polished, and there is a large amount of documentation at the Heroku Addon Provider site. They take care of billing and provide a single-sign on API for addon providers, and generally make the process seamless and pain-free. We’ve been working with them for a while, through the development of their addon platform, and they have a very solid offering now. Go forth and develop!
