Efficient. Reliable.
Kafka Applications.

Responsive is a cloud native stream processing architecture. Enhance Kafka Streams with disaggregated state, intelligent autoscaling and optimized storage for applications which don't suffer from any unpredicatble lag, are 80% cheaper to operate, and are infinitely scalable.

Product Overview

Better and more efficient.

Eliminate painful operations and reliability issues, all while reducing infrastructure costs. Responsive leverages cloud native technologies to deliver a next generation architecture for Kafka Streams.

Java SDK

End Rebalancing with One Line of Code.

End long rebalancing and restorations by replacing RocksDB with battle-tested remote storage, unlock unlimited throughput with async processing, and gain advanced features like TTL. All while maintaining complete Kafka Streams compatibility.

Remote state for replacing RocksDB with MongoDB

Async Processing for parallelizing high-latency operations

Time-to-Live for limiting storage space

Control Plane

Optimal Capacity, Automatically.

Stop overprovisioning and manually managing scale. Our purpose-built control plane automatically optimizes your Kafka Streams infrastructure based on real-time metrics.

Autoscaling policies for declaratively specifying infrastructure requirements

Metrics API for integrating our observability platform into your APM of choice

RS3 Storage

Robust state at cloud native prices.

RS3 combines the reliability of distributed databases with the cost structure of object storage, reducing your state storage costs by 7x while improving availability.

RS3 is the Responsive Streaming Storage Service built from the cloud up

SlateDB is the open source technology behind our innovations

Support

For when technology doesn't solve the problem.

The world’s foremost team of Kafka Streams experts are on your side, with contributors and committers available 24/7.

99.99% Uptime. 50% Cost.

How Responsive can cut your costs.

Did you know that over 70% of your Kafka costs come from the applications, not the brokers? Responsive makes that 70% more efficient and reliable, so you get more for less.

Instant Autoscaling

Dissaggregating storage means scaling operations are no longer a pain. Always have correctly sized applications, and stop wasting resources on idle applications.

No More RocksDB

Kafka apps need half their resources for RocksDB, more if you deploy with standby replicas. Responsive uses S3 instead, only keeping the working state on disk.

Reduced Kafka Costs

No restores and no standbys means no egress costs from the changelog topic.

Case Study

Metronome delivers usage-based billing with Responsive.

To ingest, process and serve over tens of thousands of billing events per second with strict transactional guarantees, Metronome designed their event-driven architecture using Responsive and Kafka Streams.
