About this project

What does Just Utilities add?

Tldr; This mod is a personal Modding API/Library.

The long story:
This Library mod, started as a collection of personal helpers, common code and lots of other stuff.
But it grew with my switch to "non API modding", where I am not using Forges,
Fabrics, Quilts or NeoForges API, but solely rely on Vanilla APIs and code.
And it's now a gateway to easily making mods that work on 4 mod loaders at once,
without having to write a single line of code more than once.

Warning/Disclaimer

There are only 2 safe and legit places to get this mod, Modrinth and Curseforge. If you are seeing this on any other site, be aware that this was copied with permissions, and the site may hide malware in mod files.

For Developers

It is still heavily W.i.P. and is still a personal API published under the ARR license.
(A more permissive license is planned, but it won't be open source)
You are free to use this library for your own mods, as long as you do not shade, or jar in jar it.
But do not expect stability or support, as it's still in early development,
it's prone to changes and it'll grow as I need it.
