Check out DragonflyDB (BSL): https://www.dragonflydb.io/

BSL is not OSI-approved, but it’s a much more reasonable AWS-resistant license. It’s the same license CockroachDB uses, for example.

KeyDB (BSL, acquired by Snapchat) is also an option: https://keydb.dev/

BSL is a much better license, but it’s a gamble on how long KeyDB will be supported. I don’t want to mess around with such a core part of my architecture.
