Description of the LPX plugin:​

LPX is a next-generation exlayer protection tool that will protect your server from attacks by clients such as MetaClient, Jessica, YSK, GasClient, Jigsaw and more. It is constantly updated and always on the move of all anti-exploit. It is used by more than 800 servers (now there will be more :))

LPX plugin features:​

  • ✅Avoid NettyCrashers, prevents exploits from blocking netty threads without using a ViaVersion fork;
  • ✅AntiCheat-Fix blocks several packages that cause anti-cheats to make the server use a lot of CPU;
  • ✅Dependency Free, does not require any dependencies;
  • ✅ Advanced Packet Injection, packets are analyzed and blocked before the server can decode them, which is different from any other anti-exploit;
  • ✅ Highly configurable, simple and detailed anti-cheat;
  • ✅ GUI for latest alerts;
  • ✅ Packet recorder with maximum file creation to avoid huge memory usage (switchable);
  • ✅ 1.8, 1.12.2, 1.13.2, 1.15.2, 1.16.5, 1.17.1, 1.18.2, 1.19.1+ Compatible on paper and related forks;
  • ✅ Frequent updates when a new exploit is discovered;
  • ✅ Printer/circuit compatibility with API or semi-automatic system;

Why choose LPX?​

  1. Unique to NETTY CRASHERS , some rare clients such as GasClient have NettyCrasher exploits, one type of exploit that affects not server TPS but Netty streams. NettyCrasher keeps the Netty threads busy when the packet is decoded, so the server crashes and doesn't listen for any more packets. LPX is the only anti-exploit that has this check without using any weird ViaVersion fork or Spigot fork.
  2. Custom injection and no need for dependencies , LPX uses a unique injection method compared to other anti-exploits, which guarantees high performance without using Reflections to read packets.
  3. Smooth Packet Limiter Anti-exploiters generally discourage the use of packet limiters as this can cause poor connection issues for players. LPX has an accurate way to count spam packets and a fully working VL system to prevent false flags from lagging players. If any false error is found, the config can be easily edited to fix the false flags.
  4. Printer/Schematica compatibility , usually packet limiter plugins cause incompatibility issues with this mod, LPX has a very useful automatic system that detects when the player has started using printer mode and that ensures no false kicks. It is also possible to use the API.

  5. Advanced Packet Logger , if your server is attacked by a packet exploit, you can log every packet sent by any player to understand what type of exploit they used, and we can fix it within a few days. Packet Logger can be disabled, configured and does not take up much memory thanks to the automatic deletion of old files.
  6. Simple and detailed configuration , you can edit just about anything as long as you detect false flags, you can choose to enable/disable kicks for each check, enable/disable specific checks, and change EVERY value used in the code.
