Dragonfly DB vs Redis

Redis is the original in-memory store; Dragonfly is a drop-in compatible reimplementation built around a multi-threaded, shared-nothing design.

Dragonfly DBRedis- and Memcached-compatible in-memory data store

RedisIn-memory data store for caching, queues and real-time apps

Which to pick

Pick Dragonfly DB if you want…

High-throughput in-memory caching
Redis-compatible high-performance cache
Open-source code (dragonflydb/dragonfly on GitHub)

Pick Redis if you want…

In-memory caching and real-time vector search
General purpose in-memory caching

Dragonfly DB is a Redis-compatible store focused on high-performance in-memory workloads, but does not include the vector search features of Redis Enterprise.

Dragonfly DB features

Thread-per-core architecture. Utilizes every CPU core to eliminate scaling bottlenecks and boost throughput.
Improved memory efficiency. Delivers up to 30% better memory usage compared to Redis.
Single-node cluster replacement. One Dragonfly instance can replace an entire Redis cluster, reducing node count.
Lower infrastructure cost. Optimized for modern cloud hardware, cutting total cost by up to 80% per quoted cases.
High QPS performance. Benchmarks show up to 25× higher queries-per-second than Redis.

Redis features

In-memory key-value store. Provides sub-millisecond latency for caching and queueing workloads.
Vector search engine. Retrieves relevant data from structured and unstructured sources using Redis-powered vector indexes.
Multi-region active-active replication. Delivers local-speed reads and zero-downtime failover across regions.
Tiered RAM + Flash storage (Flex). Scales to terabytes while reducing cost up to 80 % compared to pure RAM.
Enterprise security features. Includes SAML SSO, RBAC, encryption in transit and at rest.
Open-source core (Redis 8). Download and run the free open-source version on-premises or in any cloud.
