More QPS than Redis


Faster snapshotting than Redis

Effortless Scale

Dragonfly scales effortlessly, even for the heaviest workloads

Dragonfly is architected to deliver the scalability that modern data workloads require. Say goodbye to complex multi-node environments with endless configuration options and infinite points of failure. Dragonfly can effortlessly scale up to handle over 1TB of data and 4 million QPS on a single node, with a simple primary-replica pattern for high availability.


In-memory datasets on a single instance


Less memory usage

Unparalleled Efficiency

Lower Cost

Dragonfly is designed to fully utilize the processing power of modern hardware, reducing infrastructure costs by up to 90% when compared to legacy data stores like Redis. Dragonfly’s simple, vertical scaling model also means significantly lower total cost of ownership.

Reliable By Design

Dragonfly delivers the reliability your customers expect

Efficient Snapshotting

Dragonfly makes extremely efficient use of memory (i.e., no spike in usage during snapshotting), dramatically reducing the risk of out-of-memory outages.

High Availability

Dragonfly natively supports an eventually consistent primary-replica model to achieve high availability. If an outage on the primary occurs, Dragonfly will automatically failover to the replica and promote it as the primary.

Vertical Scaling

Dragonfly is a simple system with a single instance for workloads up to 1TB. This eliminates the fragility inherent to distributed clusters and dramatically improves the reliability of the system.
