Overview

Dragonfly is a Redis-compatible in-memory data store built on a shared-nothing, thread-per-core architecture, so one instance uses every core on a machine rather than a single thread. It is sold as Dragonfly Cloud, a managed service on AWS, GCP or Azure with one-click provisioning, horizontal and vertical scaling, and a monitoring dashboard.

Best for: Teams running large Redis-compatible caches who want fewer nodes and lower infrastructure cost.
Pricing: Dragonfly Cloud starts at $36/month (Flex) and $2,000/month (Business), with on-demand memory from $8.00/GB/month plus cloud provider network charges; Enterprise is contact-sales.
Runs on: Self-hosted
