Here’s what Heroku says about dyno memory usage: Dynos are available in 1X or 2X sizes and are allocated 512MB or 1024MB respectively. Dynos whose processes exceed their memory quota are identified by an R14 error in the logs.

It wasn’t clear whether I would be paying up front or be charged monthly. I left a field empty, and when the page reloaded to ask me to fix it, I was also switched back to the most expensive hosting plan.
