I found a vanilla SMP that is open for people to join.
It has a Java address and a Bedrock address so players on both can get in.
If you want normal survival with other people this is basically that.
VANILLA SMP RECRUITING PLAYERS NOW
GG.MINEWIND.NET New Server IPSuitedUp SMP Season 1 Raiding PvP
SuitedUp SMP just launched Season 1 and it is a vanilla style survival server.
The main vibe is PvP and raiding so you can fight other players and try to protect your stuff.
It is cross play so people on different platforms can join together.
They also want help with building and they say they will need mods later so you can apply after you join.GG.MINEWIND.NET New Server IP
