Calvaria is a Minecraft Java server that stays mostly vanilla and it is whitelisted. It seems made for players who want to build and hang out in a friendly place. You have to submit to join since it is not open to everyone.
It uses server side mods so you can still play without installing anything. Some of the extras include Simple Voice Chat, an audio player, vein miner, tree harvester, some crafting recipe changes for QoL, item swapping, mob and player heads, and armor poser.
The server first opened on January 28th 2026 so it is pretty new. It is listed as 16+ and it runs on 1.21.11.
