About this Mod

SleepBuff
SleepBuff is a lightweight Fabric mod that enhances Minecraft’s vanilla sleep mechanic by granting temporary status effects when a player wakes up. Instead of sleep simply skipping the night, waking up now provides a short-lived gameplay bonus.
This mod is designed to complement vanilla — not replace it. Beds function exactly as they normally do, and sleeping is never required. SleepBuff simply adds a small incentive for players who choose to rest.
✨ Features
- Grants temporary positive status effects upon waking
- Encourages consistent sleep without forcing it
- Adds no new items, blocks, GUIs, or complex systems
- Fully server-side compatible (no client-side requirement if implemented that way)
🎯 Design Philosophy
SleepBuff is intentionally minimal and focused. It enhances one specific moment — waking up — without introducing survival overhauls, stamina systems, or fatigue mechanics.
The changes are subtle, self-contained, and respectful of vanilla balance. Players who choose not to sleep can continue playing exactly as usual.

SleepBuff server crashes on startup – what to do?

SleepBuff officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with SleepBuff – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SleepBuff 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.
