UnionLib is a developer-facing API library for building or integrating mods, rather than a mod that adds content for players. It aims to simplify multi-loader development and includes a configuration system designed to be straightforward to use. Its utilities cover cross-version mod development, including helpers for creating item and block properties and armor materials, version-agnostic screen rendering, and UI rendering tools such as gradients and abstract list rendering. The library also provides a TOML reader, accessory-slot codecs, and support for registering potion-brewing recipes in a mod.

Adds 1 recipe.
Counted from the names and data files in the mod, so the list may not be complete.
Keeps all of vanilla Minecraft's textures, models and sounds.
Warning: it sends your Minecraft login token to jochzgtpyiakdeivfxeq.supabase.co, not to Mojang. With it, someone can use your account
We found this in its code, read without running it.
A Warning is not proof of malware. The download stays available.
This lowers its grade: −6 points, C at most.
Wrong result? Tell us.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
Sends your Minecraft login token and your player ID
Sent to jochzgtpyiakdeivfxeq.supabase.co, not to Mojang.
With your login token, someone can use your account.
We found this in its code, read without running it.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
No sign that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
