I found Xapros SMP and it is a chill vanilla survival server for adults only. It has players from lots of places so it feels like someone is online at almost any time.
The world is meant to be long term since it started in January 2025 and they say they will not reset. It is a good place for huge projects and megabuilds. Peak time looks busy with around 20 to 25 players online.
It runs on Fabric so redstone and farms act like singleplayer. They also added BlazeandCave advancements if you want extra goals.
There are no land claims but griefing and theft are not allowed. There is a tool to inspect blocks if something goes missing. Travel is easier with a Nether ice boat highway and there is a nice spawn plus a diamond shopping area. There is also no world border so you can live super far away if you want.
Adult Vanilla SMP That Never Resets
GG.MINEWIND.NET New Server IPHermitiaSMP Community Chaos Vanilla Plus
HermitiaSMP is a small independent survival server that is all about community stuff and people working together from different places.
It has weekly events that keep things from getting boring and they help new players feel included. The events can be in game and also real life and even art competitions.
There is optional proximity voice chat so you can talk in game if you want. The server also has event houses and community builds where you can join a house and earn points for it.
It uses a custom datapack and some quality of life mods to make vanilla feel better. For safety there are anti grief plugins like CoreProtect.
The vibe is relaxed and welcoming with a healthy amount of chaos. Players are building a nether hub and there is a collaborative spawn and shopping area plus lots of player builds and mega structures.GG.MINEWIND.NET New Server IP
