Dragonfly is an in-memory data store for caching, feature stores, job queues and other real-time workloads. It speaks the Redis, Valkey and Memcached APIs, so existing clients connect without code changes.

Drop-in APIs - Redis, Valkey and Memcached compatibility for migration.
High throughput - benchmarked at multiples of single-node Redis query rates.
Memory efficiency - lower memory per dataset than equivalent setups.
Shared-nothing design - multi-threaded core without cluster complexity.
Cloud or self-host - managed Dragonfly Cloud or your own deployment.

It suits teams outgrowing Valkey or Redis on cost or scale that want a compatible replacement. New accounts can start free with no card required.
