Spoiler: Config

★ Pre-Decode Guard
[Blocks malformed frames before ViaVersion or your decoder ever process them no wasted CPU on garbage input.]

★ Structural NBT/Item-Bomb Protection
[Blocks item and book exploits even the ones designed to slip past basic checks.]

★ Packet Sanitization
[Detects packets carrying impossible or malformed values before they reach your server logic not just oversized data, but values that could never legitimately exist.]

★ Lightweight
[Async by design, optimized and protection that doesn't cost you tick time.]

★ Packet Logger
[Large packets that take a long time to decode will be logged.]

★ Anti-Cheat Guard
[Prevents certain exploits that disable the anti-cheat system or even cause it to crash.]

🗹 WHY CHOOSE CRASHFIX? 🗹

♥ Resilience Engineering, Not Just Checks
[Bootstrap-level connection hooking with a transparent, logged fallback path protection is never silently disabled, even on unusual server builds.]

♥ Defense in Depth
[Multiple independent layers catch what a single check would miss one gap doesn't mean total exposure.]

♥ Prevention Over Patching
[Most anti-crash plugins wait for a bypass to surface, then patch it after the damage is done. CrashFix looks for values that could never legitimately exist in the first place and blocks them outright, whether an exploit using them exists yet or not. Several bypasses were dead on arrival before anyone tried them.]

[No plugin can promise 100% security, and CrashFix is no exception but this approach means we're not just chasing bypasses after they happen.]
