inputbooster api

by fluxeniteMC

InputBooster API is a Fabric library that lets other mods read input statistics, switch InputBooster's state and manage its profiles.

FabricClient-side onlyMIT LicenseOpen source1.21 – 1.21.11

What it does

Mod developers use the library to access InputBooster through a stable, versioned interface without touching its internal code.

The interface also lets a mod toggle InputBooster's active state, change its Hz setting, switch between AUTO and MANUAL mode, and save, load or list config profiles from code. It is an official developer library, published alongside the InputBooster Main Mod, which players install separately.

Runtime needs are simple. The library runs only on the client, so servers do not need it. It is published for Fabric only, across 12 release versions 1.21 – 1.21.11, and the latest file, 3.1.0 for 1.21.11, was released on 2026-06-03. The project is open source under the MIT License, released by Ahaduzzaman Khan, and its source code is public on GitHub.

Key features

  1. Live input statistics

    Read poll rate, FPS, CPS, input latency and the number of recovered inputs while the game runs.

  2. Real-time event listeners

    Receive events for attacks, queued inputs, burst mode activation and profile switches as they happen.

  3. Control of InputBooster state

    Toggle the active state, change the Hz value and switch between AUTO and MANUAL mode from code.

  4. Config profile management

    Save, load and list InputBooster config profiles programmatically.

  5. Stable versioned interface

    Changes between minor versions add to the API rather than alter it, so mods built against the library keep working as InputBooster updates internally.

Use cases

Mods that react to input

A mod can respond to attacks or burst mode events, for example to show a counter or trigger an effect.

Companion tools

A separate tool can read live stats or switch profiles without changing InputBooster's own code.

Who it’s for: Mod developers who want to integrate with InputBooster. Players who only want the input tuning itself do not need this library and should install the InputBooster Main Mod instead.

Questions

Does InputBooster API need to be installed on servers?

No. Servers do not need it; each player installs it for their own game.

Which loader does InputBooster API support?

Only Fabric. Files are published for Fabric alone, covering the 1.21 – 1.21.11 range.

Do mods built on the API break when InputBooster updates?

The interface is meant to stay stable across InputBooster updates, and each minor release extends it without removing existing calls.
