What Makes It Different

A productized NextBrick operating layer built around real enterprise workflows, not a thin wrapper around one vendor.

Streaming Control Center

Monitor topic throughput, partitions, lag, errors, retention, and consumer groups.

Schema Governance

Manage schema evolution and compatibility so producers and consumers change safely.

Stream Processing

Build enrichment, filtering, joining, and routing pipelines for operational use cases.

Reliability Tooling

Track dead-letter queues, replay windows, and incident evidence for production operations.

Real-Time Event Streaming Battlecard 1.0

70% lower TCO at equivalent throughput.

Kafka-compatible wire protocol, zero-copy ingest, KRaft-native operation, and no per-partition licensing.
