Why the models rank Redis — on best caching layer for backends
“Still the default backend cache in 2026 — richest data structures (strings, hashes, sorted sets, streams), sub-millisecond latency, universal client/framework support, and the AGPL relicensing in Redis 8 plus built-in JSON/query features restored much of the community goodwill lost in 2024”
Why the models rank Valkey — on best caching layer for backends
