Cozyvale is a new 18 plus Minecraft server that is trying to stay really close to vanilla but still feel nice to play.
From what I saw the world is survival and the owners are just a group of friends. They added a few small quality of life things like only 40 percent of players need to sleep. Leaves decay faster so you are not just staring at trees. There is a simple voice mod and a dynmap so you can see the world.
They also have stuff like re dyeable dyed blocks and player and mob head drops. You can use cauldrons to make concrete and mob grief is reduced so your builds are a bit safer.
The server is only for adults and it is meant to be a cozy relaxed community. There is no teleport and no pay to win so people are supposed to play fair and legit. If you want a simple survival world with a small chill group this server is aiming for that.
