Heroku CI and Heroku Teams Now Free for Card Paying Customers

We’ve just introduced three new changes to our pricing at Heroku, all designed to provide extra value to our customers and make cost estimation easier. These changes will kick in from September 1, 2023 onward:

  2. Your account will no longer be charged the $10 monthly fee for Heroku Teams with over five members.
  3. We’ve improved our pricing page to include hourly expenses alongside the maximum monthly costs.
