About this Mod
Auto Chunky
A lightweight, server-side utility mod that automatically pauses world pre-generation when players are online and resumes when they leave.
Perfect for servers using the Chunky mod to pre-generate their worlds! You no longer have to worry about the server lagging when players join, or forgetting to resume Chunky when the server is empty.
How it works
- Player Joins: The mod instantly pauses Chunky behind the scenes (
/chunky pause). - Server Becomes Empty: The mod starts a 2-minute timer. If no one joins during this time, it automatically resumes generation (
/chunky continue).
Commands
Requires OP / Permission level 2
/autochunky toggle- Turns the automation ON or OFF./autochunky status- Checks if the automation is currently running.
Requirements & Recommended Setup
- Server-side only! Your players do NOT need to download this to join your server.
- Fabric Loader: Version 0.18.5 or higher is strictly required.
- Chunky must be installed on the server for this mod to have any effect.
- Highly Recommended: Set
continueOnRestarttotruein your Chunky configuration! This ensures Chunky starts generating immediately when the server boots up, allowing Auto Chunky to perfectly manage pausing and resuming from the very beginning.

Auto Chunky server crashes on startup – what to do?

Server lagging with Auto Chunky – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Auto Chunky consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
