Lumenor SMP is a 24 7 custom vanilla survival server on 1.21.11 and it also lets newer versions join with ViaVersion.
It works for Java Bedrock and even cracked clients so a lot of different players can hop on.
The coolest part is the role system where you pick Passive if you want chill life or PvP if you want chaos. It lets both types of players exist on the same server without it feeling pointless.
The world has custom biomes and huge structures like ancient temples so exploration feels worth it. There are powerful rewards to find while you roam around.
There is a player driven trading shop that feels more like villager style trading and not some economy store. You can also practice in PvP and Passive arenas and keep inventory is enabled only in the arenas.
There are custom armor trims that give small buffs and the Nether is custom and very challenging. They also say the server has strong anti cheat to keep things fair and it is hosted in Germany with staff from a bunch of countries.
