Run 5GB/s of Kafka workloads for $50 per hour
Ursa, the data streaming engine powering StreamNative’s managed Kafka service, can sustain 5GB/s Kafka workloads at just 5% of the cost of traditional streaming engines like Redpanda.
Native integration with Snowflake Open Catalog
Snowflake's Open Catalog, a fully managed service for Apache Polaris™, is an open-source catalog enabling secure, centralized access to Iceberg tables across REST-compatible query engines. It is now natively integrated with StreamNative Ursa Engine.

100% compatible with Kafka API. All your existing Kafka clients and tools work out-of-the-box, now backed by a more cost-efficient and scalable data streaming engine.
No Keeper
Less management
No more time sunk into managing ZooKeeper clusters. Ursa’s leaderless architecture eliminates the need for ZooKeeper, simplifying operations in containerized environments like Kubernetes.
Lakehouse First
Lower costs
Ursa writes data directly to low-cost object storage in open table formats – so all your streaming data is immediately available as Iceberg/Delta Lake tables for querying. No more managing tiers of brokers or extra storage nodes.
