About
KasugaLib is a developer library intended to reduce the work involved in Minecraft mod development, rather than add content directly to the game. It provides streamlined registration for common elements such as blocks, items, block entities and renderers, menus and screens, models, network channels and packets, fluids, entities, textures, fonts, sounds, tags, and recipes. Its data-generation and resource tools expand where blockstate, item-model, texture, and model definitions can be placed, and support alternative definitions for models and model animations. For user-created content, KasugaLib supports JSON-defined Bedrock-style models and animations, with animation tickers that can play one or multiple animations, pause or resume them, and control their speed. The library also includes utilities for vectors, resources, lazy recomputation, and directions, plus a Create-focused variant with registration helpers for tracks, track materials, bogeys, and behaviours.
Written from Modrinth and the GitHub README . How we write it
In-game changes
Changes the game's code in 3 areas, as a library other mods build on: World renderingChanges 3 game code files in this area: drawing the terrain, sky, clouds and weather., Rendering and graphicsChanges 3 game code files in this area: drawing mobs, items, particles and textures on screen. and Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses..
Adds 1 block: Green Apple; 1 item: Example Fluid Bucket.
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.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Accepts connections from other computers
- It can accept connections from other computers.
- Can download and run new code
- The same part of the code can download data and run it as code. Auto-updaters do this, and so does malware.Not a Warning: we read its code and found no code downloaded over http or run without a check.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Found: the temporary files folder and your user folder.
- Starts other programs
- It can start another program on your computer, for example to open a link in your browser.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. It contacts 5 web addresses. See Privacy
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them.
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.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.6 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Uses folders outside the gameUses the temporary files folder.
- Starts other programsPurpose not known.
- Looked for, not foundWe looked for these in the file and did not find them.Updating itself, the webcam or microphone, an AI service.
- Modrinth and CurseForgeA release with a different file on Modrinth and on CurseForge, whose code is not the same. Each file is checked on its own. Nothing is blocked.Minecraft 1.19.2 to 1.19.4 · Forge · release 0.18 · 7 Oct 2024: Modrinthcode differs in 1 release

Privacy
We found nothing it sends about you
We read its code without running it: it contacts 1 web address while you play.
Like any connection, each address it contacts sees your IP address.
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.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of its one file, for recent Minecraft versions. See each file in Releases
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Downloads a JaVeT library file used by the mod.Explained by AI (may be wrong)Explained by an AI from the code. May be wrong.
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
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.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found12 of 37 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found48 images read
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file3,000 code files read
