About this project

What does KryptonPlus add?

KryptonPlus ⚡

KryptonPlus is a modernized, drop-in network stack optimization mod for modern Fabric Minecraft, based on PaperMC's Velocity networking innovations.

It completely rewrites Minecraft's packet encryption and compression pipelines with zero-leak native memory management, delivering maximum network throughput, lower server/client CPU usage, and ultra-low ping spikes.

✨ Key Features & Improvements

  • 🚀 Velocity Native Pipeline: High-performance libdeflate compression and native AES encryption for lightning-fast packet handling.
  • 🔄 Full ViaFabricPlus Compatibility: Intelligently handles multi-version byte streams, packet length shifts, and dynamic Netty pipeline injections without crashes or disconnects.
  • 🛡️ Zero-Conflict Coexistence:
    • Designed to work alongside e4mc without conflicting login/cipher redirections.
    • Dynamically respects PacketFixer packet limits without crashing on large payloads.
    • Compatible with ResourceTrimmer, TT20, and Eunomia.
  • 🧹 Instant Memory Cleanup: Unused native buffers and compression decoders are cleanly dereferenced as soon as network channels close.
  • ☕ Java 27 Ready: Built and tested with modern Java runtimes (Java 21, 25, 27).

📦 Compatibility & Environment

  • Mod Loader: Fabric
  • Minecraft Version: 26.3+
  • Environment: Client & Server (Works in Singleplayer, Multiplayer, and Dedicated Servers)
  • License: LGPL-3.0
