About this Mod
World Repos lets Minecraft players and map creators share and discover custom worlds effortlessly through simple online repositories.
How it works
Map creators upload a small JSON file plus zipped world files to their own website or hosting service. Players add the repository URL inside the mod, then browse, preview, and download the worlds directly from that repo — all without leaving Minecraft.
Features
Simple setup for creators: just upload a JSON manifest and zipped worlds to a web folder.
In-game interface for browsing and downloading worlds from any added or public repo.
A curated public repo list where creators can submit their repositories for easy discovery by everyone.
Perfect for map makers wanting to share, and players wanting fresh new worlds to explore.
FAQ
📁 How to make my own repository?
Create aMinecraftWorldRepo.json file with the following format:
{
"info": {
"name": "My Test World Repo",
"description": "Testing The mod",
"author": "TGGamesYT"
},
"worlds": [
{
"name": "My test world",
"description": "Testing!",
"location": "test_world.zip"
}
]
}
Host it at a public URL (e.g. https://my.site/repo/MinecraftWorldRepo.json) and place your world zips in the same directory, relative to the JSON.🌐 How to add my repo to the public list?

Launch Minecraft with the mod installed, open the mod's menu, click “Add New Repo”, paste the link to the repo (the location where the json is located, but without the json), and you’re good to go! You can now browse and download worlds directly from that repository.Available Versions
