The Lakehouse-Native Data Streaming Platform for Kafka and Pulsar
Run mission-critical Pulsar messaging and cost-efficient Kafka streaming — all powered by Ursa, no app changes.
Up to 95% Lower Kafka TCO
Move Kafka to Ursa — no broker disks, no copies, no inter-AZ replication.
Two Services, One Engine
Pulsar and Kafka on one lakehouse-native engine.
Zero App Rewrites
Keep your Kafka and Pulsar APIs — no app rewrites needed.
Ursa Everywhere: Lakehouse-Native Streaming Across All Deployments
Ursa, our lakehouse-native streaming engine, is now available across Serverless, Dedicated, and BYOC deployments — with 90-95% cost reduction and VLDB 2025 Best Industry Paper recognition.
• THE TRAPS
Kafka's Cost, Scale, and Elasticity Traps
Hidden Cost Traps
Inter-zone transfer, disk replication, and over-provisioned compute quietly inflate Kafka’s total cost.
Connector & Copy Sprawl
Moving data to lakehouses needs fleets of connectors and duplicated copies—adding latency and fragility.
No True Queue Semantics
Work queues, retries, and DLQs require extra patterns and services—raising complexity and tail latency.
• THE WAY OUT
A Lakehouse-Native Streaming Backbone for Your Entire Organization
10× faster and up to 95% lower Kafka TCO—that's why Fortune 500s and unicorns trust StreamNative to run mission-critical messaging and streaming.
StreamNative is Recognized in The Forrester Wave™: Streaming Data Platforms, Q4 2025

• HOW WE DO IT
Build Your Streaming Backbone with StreamNative
StreamNative combines the heritage of Apache Kafka and Apache Pulsar with the award-winning Ursa engine to deliver four core capabilities—Kafka, Pulsar, Universal Connect, and Universal Linking. Together, they replace fragmented systems with a single, lakehouse-native streaming backbone.
Kafka Service
Replatform Kafka on Ursa for lakehouse-native streaming. Keep your Kafka APIs and ecosystem; gain a leaderless, diskless engine that cuts cluster sprawl and writes directly to Iceberg/Delta.
Native Kafka service
Up to 95% lower Kafka TCO
Pulsar Service
Run production queues and pub/sub with Pulsar. Multi-tenant, durable, geo-replicated messaging with low latency at global scale—for mission-critical businesses such as payments, orders, IoT, and internal services.
Multi-tenant, geo-replicated messaging
Predictable low-latency delivery
Universal Connect
Use a single interface for Kafka Connect and Pulsar IO. Configure sources and sinks once to move data between databases, SaaS apps, warehouses, and your lakehouse—without custom glue code.
Unified Kafka Connect & Pulsar IO
No custom glue code required
Universal Linking
Mirror Kafka clusters into Kafka Service on Ursa with full-fidelity topics, schemas, and consumer offsets. Migrate, fan-out, or build DR in real time while streams become Iceberg/Delta tables in the background.
Full-fidelity topics, schemas, and offsets
Real-time migration and disaster recovery
• THE ADVANTAGE
Built to Run Real-Time Business at Any Scale
Low latency, high throughput, and lakehouse-native by design.
One architecture for queues and streams
Choose Pulsar for low-latency messaging and Kafka for high-throughput streaming—both powered by Ursa for a consistent, modern operating model.
Streams become tables by default
Data lands directly in Iceberg/Delta under your catalog, eliminating fragile ETL pipelines and bolt-on stream-to-table tools.
Object storage economics, real-time performance
Ursa uses a leaderless, diskless design to deliver ultra-low-cost topics and high throughput without sacrificing low latency.
Run it your way
Choose Serverless, Dedicated, BYOC, or Private Cloud to match your security, compliance, and operational requirements.
Built for today—and for Orca
A rock-solid real-time backbone now, and the trusted foundation for running agents safely when you’re ready.

• THE PLATFORM
All the Streaming You Need to Move Business Data in Real Time—on One Platform
Mission-critical, low-latency messaging and high-throughput data streaming in one platform.
Pulsar Service
Production-Proven Message Queue
Multi-tenant, durable, geo-replicated messaging with low latency at global scale—for mission-critical businesses such as payments, orders, IoT, and internal services.
Pub/sub and queue semantics in one system
Strong durability, per-key & per-partition ordering, DLQs & retries
Geo-replication and seamless scaling/maintenance
100× lower tail latency with predictable performance
Kafka Service
Lakehouse-Native Kafka Streaming
Keep your Kafka APIs while Ursa, the storage engine for the runtime, provides a cloud-native, lakehouse-ready engine that eliminates Kafka cluster sprawl and can cut TCO by up to 95%—with no app changes.
Native Kafka service — tools and apps work unchanged
Writes streams directly to catalog-governed Iceberg/Delta tables
No broker disks or cross-AZ replication; separate compute & storage
Up to 95% lower TCO with predictable performance
• USE CASES
What Teams Build on StreamNative
Modernize your Kafka & messaging estate
Migrate from self-managed Kafka and legacy queues onto a single platform. Use Kafka and Pulsar to replace brittle point-to-point pipelines with topics and queues that scale, audit, and recover cleanly
Lakehouse-Native Analytics
Use Kafka + Connect to land events directly in Iceberg/Delta. BI, ML, and data science teams query fresh data without nightly batch jobs or extra "Kafka → table" tools.
Event-driven microservices
Back your microservices with Kafka Service and Pulsar Service. Publish events instead of coupling services with RPC, and consume them from multiple services at their own pace.
Agentic AI Ready
When you're ready to run agents, Orca plugs into the same backbone. Agents get live, contextual data from streams and tables—and you keep fine-grained control and audit of what they see and do.
• SUCCESS STORIES
Proven in Production
StreamNative is built for teams at the intersection of real-time systems, data, and AI initiatives.
