This works, but the dyno spins down after a few hours. We're working on a more permanent solution.
Run Radish on Heroku (with Redis To Go!)
First, you'll need an account with Radish. Sign up!
Then, fork this repository, and run:
heroku create YOURAPP-radish --stack cedar heroku config:add RADISH_KEY=[YOUR RADISH API KEY] REDIS_URL=[YOUR REDIS URL] git push heroku master
Make sure to replace the "YOUR" stuff (your app name, api key, redis url) with your real information. Once that works, watch the stats roll into Radish!
Open up a new support request if you have any trouble getting this working.
