Valkey is an open-source (BSD-3-Clause), high-performance in-memory key-value data structure server forked from Redis before its license change, backed by the Linux Foundation. It supports rich native data structures, caching, pub/sub messaging, Lua scripting, clustering, and an extensible plugin/module system.

Use cases

• fast in-memory cache with LRU eviction for my web app
• self-hosted Redis alternative with a permissive open-source license
• key-value store for session data and rate limiting
• lightweight message broker using pub/sub
• distributed lock manager for microservices
• primary low-latency datastore for realtime workloads
• run a Redis-compatible server in Docker

When to choose

• you need a battle-tested, Redis-compatible in-memory datastore under a fully open BSD license
• you want microsecond-latency caching, pub/sub, or data structure operations
• you need clustering, replication, sentinel, TLS, and a module/plugin ecosystem
• you want a Linux Foundation-governed project with active releases and strong community support

When to avoid

• you need durable disk-based storage as the primary design goal rather than in-memory performance
• you depend on Redis-specific proprietary features or modules not ported to Valkey
• you need a managed cloud service rather than self-hosting (though many clouds offer Valkey)
• you require SQL or relational data modeling
