About this project

What does inputbooster add?

InputBooster

InputBooster is a client-side Fabric mod that improves input handling when Minecraft is running at low FPS or experiencing short stutters.

When Minecraft is under load, quick clicks or key presses can sometimes be missed. InputBooster checks inputs more frequently and can temporarily buffer some inputs so they can be handled on the next valid game tick.

Features

  • Higher-frequency input polling
  • Short input buffering
  • Input recovery during short FPS drops
  • Duplicate hit protection
  • CPS limiter
  • Sprint and W-tap assistance
  • Auto-strafe and movement helpers
  • Optional input replay recording and playback
  • Per-server profiles
  • In-game input statistics
  • Safe mode
  • Custom keybinds

The mod is client-side and does not require anything on the server.

Requirements

  • Minecraft: 1.21.x / 26.1.x
  • Fabric Loader: 0.16.0+
  • Fabric API
  • Java 21+

Installation

Install Fabric Loader and Fabric API for your Minecraft version, then put the InputBooster .jar file into your mods folder.

If you find a bug or compatibility problem, please report it on GitHub with your Minecraft version, Fabric Loader version, InputBooster version, and any relevant logs.

InputBooster is developed and maintained by Ahaduzzaman Khan.
