Name: [Unsupported] Server Hardcore
Author: SpLatOniQ

Server Hardcore makes a new world on the server each time a player dies in a hardcore world, then restarts the server by itself.

FabricServer-side onlyMIT LicenseOpen source1.20 – 1.21.9

What it does

When a player dies on a server with hardcore enabled, the mod generates an entirely new world and restarts the server, so the next session begins fresh. It is completely free and aimed at groups of friends who want deadly mistakes to matter for the whole server. The world needs hardcore mode enabled in server.properties and level.dat, and the server needs hardcore set in the same files, or the reset will not take effect. The Fabric build is server-side only, so players join without installing anything, and the code is open source under the MIT License for 1.20 – 1.21.9.

Key features

Automatic world reset
A player's death triggers a brand-new world and a server restart with no manual steps.
Clearer restart messages
The restart opens a new terminal and prints a message that makes the startup phase easier to follow.
Death message handling
The dead player's name is left out of the kick message, which adds a notice after the usual text.

Questions

Does Server Hardcore need to be installed on the client?

No. Only the server needs it, and players join without installing anything.

What must be enabled before the reset works?

Hardcore mode has to be enabled in server.properties and level.dat, because the reset depends on the hardcore setting in both files.

What the author says

Now, every time someone dies, the server will simply restart itself and create an entirely new world! completely free of your or your friends deadly mistakes! The world needs to be in hardcore in order to work, if it won't work in hardcore check if either server.properties or level.dat have hardcore enabled
