AutoMQ
Cloud-native Kafka alternative built on S3 with zero disk management, instant elasticity, and millisecond latency. Trusted by JD, Grab, and Tencent for high-scale event streaming.
AutoMQ is an open-source alternative to:

AutoMQ is a cloud-native, diskless Kafka built directly on cloud object storage (S3, GCS, Azure Blob). It eliminates traditional Kafka’s disk management overhead while delivering sub-10ms P99 latency, infinite storage scalability, and zero cross-AZ data transfer costs.
Key Features
- Diskless Architecture: Runs Kafka entirely on object storage with no EBS volumes or RAID configurations, eliminating disk failures and operational overhead.
- Sub-10ms P99 Latency: Achieves millisecond-level latency through local-zone brokers and memory caching, matching traditional Kafka performance.
- Instant Elasticity: Stateless brokers auto-scale in seconds without capacity planning or partition reassignment, adapting to real-time workload demands.
- Zero Cross-AZ Costs: Shared storage eliminates replica synchronization traffic between availability zones, reducing data transfer fees to $0.
- 100% Kafka Compatible: Fully compatible with Apache Kafka APIs, tools, and client libraries, requiring no code changes for migration.
- Unlimited Storage: Leverages cloud object storage’s durability (11 nines) and capacity, scaling infinitely without over-provisioning.
- Multi-Cloud Support: Deployable on AWS, GCP, Azure, and Oracle Cloud, with seamless integration into existing cloud environments.
- Enterprise-Grade Reliability: Trusted by major enterprises like JD.com, Grab, and Tencent for mission-critical event streaming workloads.
Tech / Self-Hosting
AutoMQ is a fully managed cloud service with a self-hosted option available via open-source deployment. The open-source version (GitHub: automq/automq) supports self-hosting on any cloud provider or on-premises infrastructure. The project is built in Go and leverages cloud-native technologies for scalability and resilience.
