AntiPlayerCrasher

AntiPlayerCrasher is a lightweight client-side Fabric mod for Minecraft 1.21.10 that protects your game from malicious packet-based crash attempts.

Some exploit plugins and abusive servers send intentionally broken packet data to force client crashes. This mod intercepts the most common crash packet paths and validates incoming values before Minecraft processes them. Suspicious packets are dropped safely instead of crashing your game.

Features

Blocks malicious position packets
Blocks malicious explosion packets
Blocks malicious particle packets
Detects invalid, non-finite, and extreme numeric values
Lightweight and focused on stability

Why use it

Prevents common PlayerCrasher-style client crashes
Works fully client-side (no server installation needed)
Keeps gameplay unchanged (no intrusive UI/features)
Minimal dependency footprint

Compatibility

Minecraft: 1.21.10
Loader: Fabric Loader 0.18.3+
Java: 21+
Fabric API: not required

Notes

AntiPlayerCrasher is a defensive utility mod.
It does not add content or gameplay mechanics; it only hardens packet handling to keep your client stable on untrusted servers.
