AutoHibernate
Automatically puts your Minecraft server to sleep when no players are online — zero CPU usage, instant resume.
About this Mod
AutoHibernate is a server-side Fabric mod that automatically puts your Minecraft server into deep hibernation when no players are connected, and seamlessly wakes it up the moment someone joins. By hibernating the server, you save significant CPU and power resources while keeping your world exactly as players left it.
✨ Key Features
- Zero Idle Resource Usage — Server CPU usage drops to 0% (or near 0%) when the server is empty.
- Preserves World State — Block updates, entity movements, crop growth, and random ticks are completely paused.
- Freezes Local Difficulty — In-game time stops ticking, preventing regional difficulty from artificially increasing while nobody is playing.
- Seamless Resuming — The server instantly wakes up without any noticeable lag or delay when a player connects.
- Console Support — Commands entered into the server console continue to work perfectly fine while the server is hibernating.
🎮 Commands
You can manually control the hibernation behavior using the /autohibernate command:

❓ FAQ
Can you update this to a newer version of Minecraft?
Try using the latest version of the mod first! It often works perfectly fine even if Modrinth doesn't explicitly list the newest Minecraft snapshot or minor version as supported.
Can you port this to an older version of Minecraft?
Probably not, as this would likely require porting to a completely different mod loader.
Can you port this to Forge/NeoForge/Paper?
I may port this to other mod loaders in the future if I have the time, but for now, it remains a Fabric mod.

AutoHibernate server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

AutoHibernate officially supports fabric for Minecraft 26.1.2, 26.1.1, 26.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with AutoHibernate – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if AutoHibernate consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
