Hey there – yes, the pricing page is a bit confusing. We’re going to fix that soon! Meantime, here’s the deal.
For free, you can run:
- 3 shared-cpu-1x VMs with 256MB RAM full time
- 3GB storage volumes
- 160GB outbound data transfer
As long as you stay on shared-cpu-1x VMs and provision 3GB or less of storage volumes, you’ll stay in the free tier.
Autoscaling has to do with the number of instances you are running, and it defaults to disabled. As long as you don’t change this, you should be ok.
Hope that makes it a little more clear!
