ServerBooster-Free

⚡ ServerBooster ⚡

Free Server Performance Plugin for PaperMC, Spigot & Purpur

Lag killing your server? Fix it in 30 seconds.
Drop in the JAR. No config needed. Just works.

What Does It Do?

ServerBooster finds what's lagging your server and fixes it automatically.
Mobs, hoppers, redstone, chunks — it handles everything.

✅ All Free Features

⚡ Works Everywhere

• One JAR for PaperMC, Spigot, Purpur, and all forks
• Auto-detects your platform and picks the best optimizations
• No extra dependencies required — just drop and go

Beautiful In-Game Dashboard

• Live TPS sparkline, memory gauge, and server stats
• Toggle any module on/off with one click
• Per-world entity counts and loaded chunks
• Alert history — see what optimizations are running

Smart Entity Management

• Per-entity-type limits with radius and chunk caps
• AI freezing for mobs in inactive areas — they stop thinking, you stop lagging
• Aggressive despawning cleans up excess mobs
• Breeding and growth rate throttling to prevent animal farm lag

⚙️ Hopper & Redstone Optimizer

• Sleeping hoppers — if they're not moving items, they stop ticking
• Redstone clock detection — auto-throttles lag machines
• Observer loop detection — stops infinite loops without breaking farms
• Dust deduplication — reduces same-tick wire updates

Dynamic View Distance

• View distance scales down when TPS drops, scales back up when it recovers
• Idle players get reduced distance automatically
• Your active players always get the best experience

Item Stacking

• Ground items merge together instead of piling up
• Hologram labels and glow effects so players can see what's stacked
• Fewer entities on the ground = better performance

Even More Optimizations

• Chunk Packet Throttling — Controls how fast chunk data goes to players
• Portal & Piston Budgets — Prevents lag machines
• Elytra & Trident Speed Caps — Stops fast travel from overloading chunks
• Crop Growth Throttling — Reduces farm tick overhead in empty chunks
• Furnace & Dropper Sleep — Idle machines stop ticking
• Faster Leaf Decay — Cleans up floating leaves fast
• Auto Garbage Collection — Smart JVM memory management
• Console Filter — Hides spammy log messages
• Spawner Throttling — Reduces spawner load during lag
• TPS-Based Commands — Auto-run commands when TPS drops
