Anti Client Crasher

Protect yourself from malicious servers.

This lightweight Fabric client mod protects your Minecraft client from server-side crash

exploits that attempt to freeze or crash your game through malformed packets, extreme values,

and resource exhaustion attacks.

Why do you need this?

• some server owners (or griefers with plugin access) can send specially crafted packets (such as extreme explosions, particle spam, invalid time packets, massive sounds, and long messages)

• that cause the client to freeze, leak memory, or crash completely — even on vanilla clients with no mods.

• Anti Client Crasher blocks these dangerous packets before they can harm your game.

• Blocks malicious Explosion packets with extreme coordinates or power

• Prevents particle spam and oversized particle packets

• Sanitizes dangerous SetTime packets

• Limits extreme sound volume/pitch

• Blocks oversized chat and system messages

• Lightweight with minimal performance impact

• Clear in-game warnings when malicious packets are blocked

** Supported Versions **
