Dragonfly
An in-memory data store without limits for real-time applications.

Dragonfly is a high-performance, multi-threaded in-memory data store designed as a drop-in replacement for Redis, Valkey, and Memcached. It delivers up to 25x more queries per second than Redis while reducing infrastructure costs by up to 80% through its efficient multi-threaded architecture. Dragonfly Cloud is a fully managed service offering sub-millisecond latency, enterprise-grade security, and 24/7 support for demanding workloads like ML feature stores and vector search.
Dragonfly uses a multi-threaded architecture that is fully API-compatible with Redis, Valkey, and Memcached, allowing users to migrate by simply changing their endpoint while gaining significant performance and cost improvements.
