Protobuf-first data infrastructure
Ironclad data quality
Attach schemas to Kafka topics, ensure backward compatible schema evolution, and eliminate runtime registration errors, all while maintaining compatibility with the Confluent ecosystem.
Integrate deeply with your existing schemas
Manage message-to-topic mappings right in your schemas, rather than in an opaque runtime registry or a generic infrastructure-as-code system.
Because it's powered by a complete Protobuf compiler, the BSR handles imports automatically and works correctly with both the binary and JSON encodings.
Fully replace the Confluent Schema Registry
Get first-class Protobuf support without an expensive migration.
The BSR implements the same API as the Confluent Schema Registry, so it works with most Kafka producers and consumers, downstream systems like kSQL and Kafka Connect, and management tools like AKHQ.
Eliminate runtime registration errors
Validate that schema changes are backward compatible at build time — in IDEs and GitHub pull requests — and when they're published to the BSR.
If breaking changes are unavoidable, the BSR's governance workflow ensures that the right team members sign off.
Validate and transform data in motion
Insulate your Kafka cluster from rogue producers with a lightweight gateway that speaks the Kafka protocol.
The gateway can validate and transform in-flight data, ensuring that it matches the expected schema and complies with higher-level data contracts.
