High-performance Redis-compatible in-memory datastore with 25x better throughput
As of 29 August 2026, Dragonfly is free to use. Dragonfly is a modern in-memory data store built on a thread-per-core architecture offering Redis API compatibility. Softwr lists it under Databases. Dragonfly is available on Web.
Overview
What Dragonfly does
Dragonfly is a high-performance in-memory datastore designed as a Redis and Memcached compatible alternative. Built on a novel thread-per-core architecture with new algorithms and data structures, Dragonfly achieves 25 times higher queries per second than Redis (3.97M QPS versus 718K) while using 30% less memory. The platform maintains full API compatibility with Redis and Memcached, allowing existing applications to migrate with minimal code changes. Dragonfly is optimized for low-latency caching, real-time feature serving for machine learning applications, concurrency-safe message queues with high throughput, and real-time leaderboards. The platform supports caching workloads up to 1TB with 1M peak throughput per instance. Dragonfly Cloud is a managed service offering serverless deployment with auto-scaling, while Community Edition is available as open source.
What people use it for

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Dragonfly.
- Flex tier starting at $36/month may be underpriced, requiring careful usage monitoring
- Business tier $2,000/month represents significant jump in cost
- Limited to in-memory storage, not suitable for cold data or archival
- Bring-your-own-cloud requirement on Business tier adds operational complexity
- Cloud availability dependent on AWS/GCP/Azure uptime
