Lumi Hardcore is a public hardcore survival SMP where you only get one life. When you die you get put into spectator mode until the next reset so every choice feels serious.
The worlds are meant to reset on purpose every 60 days in real time. That way each season starts fair and everyone has to build up again from nothing.
The gameplay stays mostly vanilla with a few lightweight datapacks for decoration and quality of life plus clean death handling. There are no gameplay changing mods and no pay to win stuff.
It runs on Minecraft 1.21.11 and it is online mode only so cracked clients are not allowed. There is also optional proximity voice chat with Simple Voice Chat if you want it but you do not need it to play.
It seems made for players who like tense survival thoughtful progression and a calm respectful community.
