The archived API

The status of the separate InputBooster API repository, what it offered, and why it does not work with 26.x.

1 min readInputBooster 4.1.2-alphaMinecraft 26.2 / 26.3

There are two repositories with the InputBooster name. The mod and this documentation come from one. The API is a separate, archived project that is not connected to the current tree.

Its status

The API repository's own README opens with the conclusion:

text

InputBooster API - No Longer Maintained
 
> Maintenance has ended. This repository is no longer actively developed
> or supported. It is preserved for reference only.

What it targeted

Property	The archived API	The current mod
Minecraft	`>=1.21 <1.22`	26.2 and 26.3
Java	21+	25
Loader	Fabric only	Fabric and NeoForge
API version	`3.1.0`	—
Status	Archived, unmaintained	Active, alpha

What it offered

The API exposed live statistics, configuration controls, profile helpers, latency metrics and an event listener surface, without forcing dependent mods to require InputBooster at runtime.

Its own quick-use example:

java

if (InputBoosterAPI.isLoaded()) {
    InputBoosterAPI api = InputBoosterAPI.getInstance();
    int hz = api.getPollRateHz();
    api.setAutoMode(true);
}

And a snapshot helper for HUD and debug overlays:

java

InputBoosterStats.snapshot()

How it was meant to be wired in

The API's maintainer notes describe the integration as a manual step:

text

Copy impl-stub/java/dev/inputbooster/api/impl/InputBoosterAPIImpl.java
into the main InputBooster mod source tree and register it after
initialization.

Why it is not connected

Reason	Detail
The Minecraft version moved	The API is pinned to 1.21.x. The mod is 26.2 and 26.3
The Java version moved	The API needs Java 21. The mod needs Java 25
The engine was rewritten	The 4.1.0 engine introduced `InputEngine`, a new state machine and new diagnostics. The API's surfaces do not map onto it
Maintenance ended	The repository states it should not be assumed to receive compatibility updates

What to use instead

You want to…	Use
Read live input statistics	The overlay and the Overview tab of the settings screen
Change a setting from another mod	The config file, or the settings screen
React to input events	There is no public event API in 4.1.2-alpha
Build a profile	The profiles screen and `inputbooster_profiles.json`
Read the latency figures	The profiler and the session statistics
