🛡️ NoClientExploits

A lightweight, client-side Minecraft mod that shields you from malicious servers. Some servers send deliberately broken packets to freeze, crash, or fingerprint your game — NoClientExploits quietly blocks them before they ever reach you. 🧯


✨ Features

  • ✅ Crash Protection — Neutralizes the packets exploit clients use to hard-crash you:

    • 🧭 IllegalPosLook — teleports with Infinity / out-of-bounds coordinates that shatter your hitbox.
    • 💥 Explosion Velocity — oversized knockback (including ExplodeBypass) that launches you into oblivion.
    • 🎆 Too Many Particles — billion-particle packets that lock up your render thread.
  • ✅ Block Local URLs — Stops a remote server from aiming resource-pack downloads at localhost / your LAN to probe your private network. 🔒
  • ✅ Client Brand Spoofer — Report your client as vanilla so servers can't fingerprint you as modded. 🕵️
  • ✅ In-Game Config Menu — Toggle every protection on the fly with a clean ModMenu screen.
  • ✅ Chat Alerts — Get a subtle heads-up in chat whenever an attack is blocked.

🎮 Why Use NoClientExploits?

  • 🧱 Stay Online — Griefers can't kick you off with a single crash packet.
  • 🛰️ Protect Your Network — Your client won't be tricked into scanning your own machine.
  • 🎭 Keep a Low Profile — Blend in as a vanilla client when you want to.
  • 🪶 Lightweight & Client-Side — No server install, no bloat, no performance cost.
  • ⚙️ Fully Configurable — Every feature is a simple ON / OFF toggle.

📦 Requirements

  • Fabric Loader + Fabric API
  • ModMenu (optional) — to open the config screen

⚔️ Play on any server with confidence — NoClientExploits has your back.
