Heroku is deprecating support for Apache Kafka on Heroku versions 2.8 and 3.7. This deprecation is part of our documented version support policy. The end-of-life date is October 28, 2026.
Our schedule for deprecating all Apache Kafka 2.8 and 3.7 clusters is as follows:
- July 28, 2026: We send a deprecation notification to Apache Kafka on Heroku 2.8 and 3.7 users.
- August 28, 2026: You can’t create Kafka 2.8 and 3.7 clusters after this date.
- September 28, 2026: Forced upgrades on deprecated single-tenant Kafka 2.8 and 3.7 clusters start.
- October 28, 2026: We start restricting access and deleting Kafka 2.8 and 3.7 clusters after this end-of-life date.
We urge you to upgrade your cluster to the latest version as soon as possible.
