What is your choice for Redis-compatible in-memory data storage?

I personally changed my XenForo server from Redis to KeyDB about 2 years ago mostly to gain multi-threading and what seemed at the time to be a well supported fork of Redis. It has been just over 2 years since the new owner of KeyDB, Snap (parent company of Snapchat), took over the company and in that time it has released only a single update and that was 20+ months ago. Not really what I would considered a well supported product.

I believe my next move is onto Valkey. Valkey 8.0, released in September 2024, introduced multi-threading to this Redis fork. Valkey is an open-source project stewarded by the Linux Foundation, with strong community engagement and collaboration. Valkey 8.1, released in April 2025, is reported to have brought enhanced performance, reliability, and usability. Which is unlike the lack of updates and innovation seen in both Redis and KeyDB over the last couple of years.

Just looking to hear positive or negative experiences with any in-memory data storage products you may be using.

I've been using Valkey via Ubuntu LTS PPA for 7 months now; so far it's very stable and there are no issues.

I'm using Valkey on Almalinux 10 currently.

Valkey is really the answer here. It has been adopted by Fedora, Red Hat, Debian, Ubuntu, Arch, and pretty much all other major distros. Some (Fedora) have even gone so far as to do in-place replacements of Redis with Valkey due to the license change. In fact I'm the author of that change in Fedora land (which trickles down to Red Hat, AlmaLinux, etc.): https://fedoraproject.org/wiki/Changes/Replace_Redis_With_Valkey

Valkey is a phenomenal team to work with and they're really pushing things forward for the open source community while Redis had been stagnating for years anyway.

Did some interesting benchmarks https://github.com/centminmod/redis-comparison-benchmarks. Redis 8 definitely caught up for performance. But licensing if you're a for profit biz would lend more favourably to Valkey. Everyone else take your pick
