Command on Interval
by FelixAgairu
Command on Interval is a Fabric server mod that runs in-game commands on a repeating timer, with settings configurable per command.
What it does
The mod lets a server owner schedule one or more commands to run automatically after a set delay and then again at a fixed interval. Each command is set in the mod's configuration, so the timing and the command text can be changed without editing code. The interval can be counted in game ticks, where 20 ticks make one second, or in seconds. Multiple commands can be listed and a cycle mode runs them in turn.
Installation needs Fabric API and Tiny Config Manager Lib alongside the mod on Fabric. Players join without it, since only the server has to run the mod. Files are published for Fabric 1.21 and 1.21.1, with 0.4.0-alpha for 1.21.1 as the latest build. The source code and issue tracker are public, and the mod is open source under the Mozilla Public License 2.0.
Key features
Repeating command timer
A command runs once after a configured delay and then again at a set interval for as long as the server is running.
Multiple commands
More than one command can be listed, so several actions can be scheduled from the same configuration.
Cycle mode
With cycling enabled, the listed commands run one after another in order instead of all at the same time.
Tick or second timing
Intervals can be measured in game ticks, matching the 20 ticks per second of the game clock, or in plain seconds.

Use cases
Scheduled server announcements
A server owner can run a broadcast or reminder command at a fixed interval, with the first message delayed after startup.
Recurring in-game events
Commands that trigger effects or resets on a timer can be set up without a separate scheduling plugin.
Who it’s for: Server owners who want commands to run on a timer without writing code. Players need nothing installed, since the mod works on the server alone.
How it compares
Default commands is a server-side Fabric mod under the MIT License, but it is built for 1.21.11 and needs a client-side optional install, so it differs in version and environment. Rain Delay is a server-side only Fabric mod, open source under the MIT License, for 1.21.5 – 26.3, so it covers newer versions than this mod. Unlimited Tick Rate Control is also server-side only and open source under the MIT License, but it only targets 1.21.7 – 1.21.8 and changes the tick rate instead of running commands.
