About this project

What does Packet Capper add?

Packet Capper

Packet Capper is a lightweight and efficient networking utility mod for Minecraft.
Instead of removing packet limits entirely, which can cause severe performance issues, this mod introduces configurable controls that let you set both the maximum number of packets per tick and the maximum payload size.

This ensures smoother gameplay, prevents network overload, and provides a safer alternative to “infinite packet” mods.

Features

  • Configurable packet cap: set the maximum number of packets per tick.
  • Configurable payload size: control the maximum size of each packet’s data.
  • Performance-friendly: avoids unnecessary strain on the client/server.
  • Safer networking: prevents accidental or intentional network flooding.
  • Lightweight design: minimal overhead, simple to configure.

Configuration

All limits are fully adjustable via the configuration file.
This allows you to fine-tune the balance between performance and flexibility, depending on your server or modpack needs.

Why use Packet Capper?

Other mods that simply remove packet limits can lead to:

  • Excessive memory usage
  • Lag spikes and degraded performance
  • Potential crashes on servers

Packet Capper solves this by giving you control: you decide the limits, ensuring stability without sacrificing functionality.
