Valkey

What Valkey is

Valkey is an open-source key/value datastore for caching, message queues, and use as a primary database. It supports strings, numbers, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, and other data types. It can run as a standalone daemon or in a cluster, with replication and high-availability options. Lua scripting and module plugins can add commands and data types. The project describes uses such as caching database or API results, session tokens, rendered HTML, reports, leaderboards, matchmaking, and AI or ML inference outputs. Valkey can be installed from source, in Docker, through macOS package managers, or with package managers for Linux and BSD distributions. It is not officially supported on Windows, though installation using WSL is described for development. The Linux Foundation backs the project, which says it will remain open source. Valkey recommends restricting network access to trusted clients and provides ACL-based authentication and optional TLS. Its guide warns that it binds to all interfaces without authentication by default, so configuration and network restrictions matter.
