**BossTimer** is a lightweight, server-side Fabric mod that lets server owners create and run **configurable countdown timers** displayed using Minecraft’s boss bar.
## What it does
BossTimer allows you to define named timers in a simple JSON config and start them with commands. Each timer:
* Displays a live countdown in a boss bar
* Updates text and progress in real time
* Can run commands before and after the timer ends
* Supports trigger messages at specific remaining times (for example, “10 seconds left”)
* Automatically syncs to players who join while a timer is already running
## Why download it
This mod is ideal for:
* Server restart warnings
* Event countdowns
* Scheduled announcements
* Any situation where players need a clear, visible timer
It’s fully server-side, requires no client mods, and integrates with permission systems like LuckPerms.
## Important info before downloading
* **Fabric loader + Fabric API required**
* Server-side only (players do not need to install anything)
* Timers are defined in `config/bosstimer_commands.json`
* Active timers are canceled on config reload for safety
Simple to configure, reliable for players, and designed for real-world server use.
