Valkey

Open source high-performance key/value datastore supporting caching, message queues, and primary database workloads. Backed by the Linux Foundation and licensed under BSD, it stays open source with no licensing changes.

Forked from Redis 7.2.4 to preserve an open ecosystem, Valkey is adopted by major cloud providers and enterprises such as Ericsson and ByteDance. Managed Valkey offerings are available from hyperscalers and database vendors, while official client libraries cover Python, Java, Go, Node.js, and PHP for straightforward integration.

Key capabilities:

• Standalone or clustered deployment with replication and high availability
• Rich data structures: strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs
• Lua scripting and module plugins for custom commands and data types
• Valkey Search with full-text search, tags, numeric queries, and aggregations
• Valkey Admin for visual cluster management, hot key detection, and performance diagnostics

Use cases span session caching, rate limiting, pub/sub messaging, job queues, real-time leaderboards, and primary storage for hot data. Developers can use existing Redis-compatible clients and migrate with minimal code changes.
