Cloud-native distributed messaging and streaming platform with multi-tenancy, geo-replication, and tiered storage that separates compute from storage.

Version

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
