Valkey 9 on Heroku Key-Value Store is generally available

Change effective on 19 August 2026

Valkey 9 on Heroku Key-Value Store (KVS) is generally available. All newly created KVS add-ons default to the latest version. You can provision a KVS instance with this version with the --version 9 flag.

$ heroku addons:create heroku-redis:standard-0 -a example-app -- --version 9

With the release of Valkey 9, we’re deprecating Valkey 7 per our policy. We urge you to upgrade your instance to the latest version as soon as possible with redis:upgrade:

$ heroku redis:upgrade kvs-addon-name --version 9 -a example-app

Valkey 9 introduces the Valkey-Search module that provides a high-performance search engine. See Valkey Modules for more information.
