Thank you for being a Heroku user. Starting November 28, 2022, free Heroku Dynos, free Heroku Postgres, and free Heroku Data for Redis® will no longer be available. You can learn more about these and other important changes from our GM, Bob Wise, on the Heroku blog.

Existing free dynos and Heroku data add-ons will be impacted, so action by you is required. To prevent any disruption to your apps or data using free plans, you will need to upgrade from a free plan to a paid plan before November 28, 2022.

For instructions on how to upgrade and for other questions, please visit our FAQ.

Thank you,

The Heroku Team
