AutoRestarter

by onedes1re

AutoRestarter schedules automatic restarts for a Fabric server, either on a fixed interval or at set weekly times.

FabricServer-side onlyMIT License1.20.4

What it does

Server owners can have the server restart on a timer, for example every 12 hours. The interval is written in seconds in the config file, where 12 hours is entered as its equivalent value in seconds. A second mode lets the restart happen on a weekly schedule instead, with a list of day and time entries that the owner edits to match their own times, such as Sunday at 04:00 or Wednesday at 14:49.

Switching between the two modes is handled in config.json. The interval setting is turned off when the weekly schedule is used, and the schedule setting is turned off when the timer is used. Because the mod only restarts the server, it has no effect on the game for players who are not connected to it.

The mod is server-side only, so players join without installing anything. It is distributed under the MIT License and is not open source. Files are published for Fabric alone and cover Minecraft 1.20.4 only.

Key features

  1. Interval restarts

    The server restarts after a set number of seconds, which the owner defines in the config file.

  2. Weekly schedule

    Restart times are set as day and clock time pairs, so the server can restart at fixed points each week.

  3. Config-driven switching

    A single setting in config.json selects the interval mode or the weekly schedule mode, and the other is turned off.

  4. Restart of the Fabric server

    The mod restarts the Fabric server itself, so no manual shutdown is needed at the chosen time.

Periodic memory clearing

Servers that slow down over long uptimes can be restarted on a regular interval, such as every 12 hours.

Who it’s for: Server owners running a Fabric server on Minecraft 1.20.4 who want restarts to happen at fixed times without manual action.

Questions

Does AutoRestarter need to be installed on clients?

No. Server owners install it, and players connect with no copy of their own.

Which Minecraft version does AutoRestarter support?

Only 1.20.4. The latest Fabric file, 1.0.0-1.20, was published on 2025-08-19 for that version.

How are the two restart modes chosen?

The config.json file holds both settings. Enabling the weekly schedule requires disabling the interval setting, and the reverse also applies.
