MinecraftOffline is a lifesteal anarchy server on version 1.21.11 with a permanent world that does not reset.
It runs custom written plugins that change up the gameplay and make it feel different from normal survival.
The server is based in Finland so it is a good pick for European players who want low latency.
It also says it uses reasonable hardware and a 1 Gbit network so it should handle fights and big bases pretty well.
