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

Important Notes
This is a client-side only mod.
It does not require anything on the server side.
Stay safe while playing on public servers.
