Running demos on Heroku

Running the demos of Dallinger in “sandbox” mode, will require a Heroku account and verification by providing a credit card in your Heroku account. If you only make use of Heroku’s free tier offerings, you will not be charged.

database_size = standard-0
redis_size = premium-0
