Yep! Valkey should work fine.

Recall just uses basic Redis commands - HSET, SADD, ZADD, etc. Nothing fancy.

Valkey is Redis-compatible so all those commands work the same.

I haven't tested it personally but there's no reason it wouldn't work. The Redis client library (ioredis) should connect to Valkey without issues.

If you try it and hit any problems let me know! Would be good to officially support it.
