Basic usage of Heroku is free. Each app you create has free access to 750 dyno hours per month and a 5MB database. From there, you can extend your application with add-ons from our catalog. To use any add-on, however, you must first verify your account - it’s completely free, and we require this to prevent abuse. To use any paid feature, you must also confirm that we may charge you.

You only need to verify and confirm your account once, no matter how many apps you have.

Frequently Asked Questions

Do you accept foreign credit cards?

Yes, a standard VISA, Mastercard or American Express should work regardless of issuing country. If your card doesn’t work, please submit a support ticket or email support@heroku.com.

How do you prorate charges?

Dynos & workers are prorated per second at a rate of $0.05/hr. The charge is based on the number you have set, regardless of their activity. In other words, charges are based on wall-clock time, not CPU time.

Databases charges are prorated per hour based on their applicable monthly fee.

All add-ons are prorated per second unless explicitly noted otherwise.

Why was my credit card declined?

There are a few possible reasons why your credit card might have been declined; our credit card processing service does not specify the cause. We recommend contacting your credit card provider by telephone for further information.
