ModLaunch Fabric modpacks through launchers that only support Forge.
Why no grade
How grades workFinished or replaced projects get no grade: they will not get fixes or new versions.

About
Jumploader lets Fabric mods run through a Forge-based installation, making Fabric usable in modpacks and launch tools that expect Forge. It replaces Forge with Fabric, or another configured loader, rather than combining Fabric and Forge mods in one game instance. By default, it downloads the Fabric loader and libraries for the game version in use, and can be configured to load a different Minecraft version or mod loader. It works on clients and servers, though servers need it only when launched with tools that support Forge but not Fabric; it has no effect when the launcher already supports Fabric.

No harmful code found
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.13 to 1.17.
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. No address written in the code is contacted by the code that runs. See Privacy
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.2 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. 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
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends about you
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.13 to 1.17.
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 both files, for Minecraft 1.13 to 1.17. 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 JAR files used by the mod. Downloads Fabric loader version metadata.Explained by AI (may be wrong)Explained by an AI from the code. May be wrong.
AI
No sign that AI was used to make it
We looked for AI tools in its texts, files, images and code history 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.
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.Not on Modrinth.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Nothing found
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found2 of 38 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 found5 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 file88 code files read
