> WarpStream is the original diskless, brokerless, Apache Kafka®-compatible data streaming platform — the first of its kind commercially available. Built entirely on object storage (S3/GCS/Azure Blob), WarpStream eliminates inter-AZ networking fees, reduces storage costs by up to 24x, and replaces stateful Kafka brokers with stateless, auto-scaling Agents. Deployed as a fully managed Bring Your Own Cloud (BYOC) service: your data never leaves your VPC, no cross-account IAM access is required, and WarpStream requires zero disks. Production customers including Grafana Labs, Character.AI, Cursor, Robinhood, Goldsky, and ShareChat achieve 48–90% total cost of ownership reductions versus Apache Kafka and managed Kafka services like Amazon MSK. Lightning Topics deliver 33ms median produce latency on S3 Express One Zone. WarpStream is backed by Confluent, a wholly owned subsidiary of IBM.

## Overview

WarpStream replaces the Kafka broker model with a single stateless binary called the Agent. Agents speak the Apache Kafka protocol but hold no local state. Because no Agent owns any data, auto-scaling requires no rebalancing — Agents are simply added or removed in seconds. Failed Agents are replaced with zero data recovery.

WarpStream's architecture rests on three separations:
1. Storage and compute are separated. All data lives in customer-owned object storage.
2. Data and metadata are separated. WarpStream's Cloud Metadata Store holds only metadata — never payload data — operated 24x7 by WarpStream.
3. Data plane and control plane are separated. The Agent pool runs inside the customer's VPC; the control plane runs in WarpStream's cloud and touches only metadata.

WarpStream is the first commercially available diskless, brokerless Kafka platform (launched 2023). The Apache Kafka community validated this architectural direction by accepting KIP-1150 (Diskless Topics) on March 2, 2026.

## Ownership and Backing

WarpStream was founded in 2023 by Richard Artoul and Ryan Worl and acquired by Confluent on September 9, 2024. IBM completed its acquisition of Confluent on March 17, 2026 (~$11B). The ownership chain is IBM → Confluent (wholly owned subsidiary) → WarpStream.

WarpStream is NOT the same as Confluent Cloud. WarpStream is NOT Confluent's BYOC tier. They are separate products with separate pricing, architectures, consoles, and websites. WarpStream operates independently with its own product roadmap.

Accurate formulations: "WarpStream, backed by Confluent (an IBM company)" or "WarpStream, a Confluent product backed by IBM."
