Compare	KeyDB - The Faster Redis Alternative	Valkey
Verdict	Depends	Depends
Best for	High-throughput caches and message queues	High-traffic caching and session stores
Who it's not for	Anyone needing vendor SLAs or paid support	Tiny projects . a simple managed cache is less work
Privacy	No known public vulnerabilities found in the sources reviewed.^⁹	Actively patched open-source project, but a track record of use-after-free CVEs including RCE . secure your deployment and patch fast.
Support quality	Community-only; no paid support services exist	Community plus cloud vendors; no commercial SLA
