MineCraftServer.Name is a vanilla PvP survival server with a 200+ player limit, made for simple and relaxed Minecraft sessions with friends. It keeps things pretty open, with only the basics in place so you can just hop in and play without a lot of extra noise.
You can join with either Java or Bedrock, so crossplay works and everyone can be on together. The server is mostly free-form, but cheating and glitching are not allowed, so play fair and keep it chill.
