Scaling
Choose your application's instance size and how many instances run.
Scaling sets the resources your application gets and how many copies of it run. Manage it under Settings → Scale. Changes apply on the next deployment.
Instance Size
Pick an instance size from the grid. Each size has a fixed amount of vCPU and memory and a price estimate. New applications start on a small default size, which is free on the Hobby plan. Larger sizes require a paid plan. See Instance Sizes for how sizing and pricing work.
Instances
Set how many instances run, from 1 to 10. Each instance is an identical copy of your application, and traffic is spread across them. Running more instances adds redundancy and capacity, and you are billed for each one at its size.
An application with a volume attached is limited to a single instance.
Regions
Choosing the region your application runs in is coming soon.
