Fully compatible with Redis
Dragonfly is a drop-in Redis replacement, meaning it uses the same APIs and is compatible with all of the same SDKs and tooling. Teams that switch from Redis to Dragonfly get huge performance gains and a simpler system to operate, all without changing code.
Extreme Performance
Dragonfly delivers 25x the performance of legacy software
The power of modern cloud hardware can never be realized with legacy software. Dragonfly is optimized for modern cloud computing, delivering 25x more throughput and 12x lower snapshotting latency when compared to legacy in-memory data stores like Redis, making it easy to deliver the real-time experience your customers expect.

25x
More QPS than Redis
12x
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.
1TB
In-memory datasets on a single instance
30%
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.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
