Frost Lag Lite

❄️ FrostLag Lite

A lightweight, silent anti-lag plugin for Paper, Spigot and Bukkit (1.20.1 to 26.x). It reduces server lag and improves both server TPS and player FPS without breaking NPCs, holograms, builds or items from other plugins.

Everything is configured and enabled out of the box: just drop it into your plugins/ folder and restart.

✨ Why FrostLag?

Most "clear lag" plugins wipe everything off the ground every few minutes, spam the chat with warnings and delete NPCs and holograms along the way. FrostLag works differently:

• 🔇 100% silent: cleanup never sends messages to chat or console.
• 🛡️ Leaves your stuff alone: NPCs, holograms, armor stands, item frames, villagers, named or tamed mobs and plugin items are protected.
• 🧠 Prevents before it removes: it merges items, limits entities and only tightens the rules when TPS actually drops.
• ⚙️ Works with zero setup, and everything can be tuned in config.yml.

🚀 Features

🧹 Silent automatic cleanup

• Removes dropped items, XP orbs and arrows stuck in blocks every 10 minutes (every 3 minutes while the server is lagging).
• Freshly dropped items (deaths, broken blocks) are protected for 10 seconds.
• Turn it on or off in-game with /fl auto on and /fl auto off. Your choice is saved.

📦 Item merging

Identical nearby items are merged into a single stack. Fewer entities on the ground means less work for the server and less for players to render (more FPS).

🐄 Mob limit per chunk

Stops farms, spawners and animal breeding from flooding a chunk:

• Normal: 30 monsters, 40 animals and 60 mobs in total per chunk.
• In anti-lag mode: 15 / 25 / 35.
• Spawns from plugins, /summon and spawn eggs are never blocked.

💣 Lag machine protection

Per-chunk limits for falling sand and gravel (16), primed TNT (24), minecarts (20) and boats (20).

🔍 Crowded chunk sweep

Every minute the plugin looks for chunks with piled-up items (over 150) or mobs and removes only the excess.

🐢 Automatic anti-lag mode

If TPS stays below 17 for 30 seconds, FrostLag:

• tightens the mob limits and cleans up more often;
• lowers view and simulation distance (Paper only);
• freezes mob AI in crowded chunks, such as farms.

When TPS gets back to 19, everything is restored automatically.

📊 TPS monitor

• Current, 1-minute and 5-minute TPS, plus MSPT (Paper), RAM, CPU cores and entities per world.
• /fl top lists the chunks with the most entities, with coordinates, so you can find the farm that is causing lag.
• Low TPS and freeze warnings are shown to OPs only, and can be turned off.

📋 Requirements

• Server: Paper, Spigot, Bukkit, Purpur or Pufferfish.
• Versions: 1.20.1 to 26.x. It only uses the official Bukkit API (no NMS), so it should keep working on future versions.
• Java: 17 or newer.
• On Spigot and Bukkit, MSPT and the automatic view distance reduction are not available (they are Paper features). Everything else works the same.
• Does not work on Folia or on proxies (Velocity/BungeeCord). Install it on the Paper servers behind your proxy.

ℹ️ Important: when the server starts, the Lite version prints one message in the console advertising the PRO version. It is never shown to players, and FrostLag Lite does not connect to the internet.
