Supercapybara / Railway Templates
Valkey
Valkey is the Linux Foundation's open-source fork of Redis. It speaks the Redis protocol, so existing clients, queues, rate limiters and caches connect to it unchanged, and it keeps the dataset in memory for sub-millisecond reads.
Disclosure: deploy links carry the author's Railway referral code — the author receives a usage kickback when you deploy. The template itself is free to deploy; Railway usage charges apply.
