Monthly Billing Plans automatically renew every month and can be canceled anytime (for example, you can use it for 1 month and then cancel). After canceling the renewal, you will not be charged again and can use any remaining credits until the end of your billing period.

Yearly Billing Plans have a 12-month commitment, a single billing at the start of the plan (excluding any overage credits), and come with a 30% discount automatically applied (this saving is already reflected on the pricing page).
