About
William Wythers' Expanded Ecosphere is a world-generation mod that reshapes the Overworld with nearly 200 new biomes and changes to vanilla biomes, aiming for a more realistic and atmospheric landscape. Its biomes span varied climates and terrain, including Ancient Beech Forests, Badlands Canyons, Outback Deserts, Tropical Rainforests, Snowy Peaks, and volcanic landscapes. The collection also includes underground environments such as Calcite Caverns, Lichenous Dripstone Caves, and Volcanic Chambers, alongside wetlands, islands, rivers, and coastal biomes.
Written from Modrinth . How we write it
In-game changes
Changes the game's code in 2 areas: Networking and multiplayerChanges 1 game code file in this area: connections, the server list and what is sent between your game and a server. and Mobs and their behaviorChanges 1 game code file in this area: mobs, animals, villagers, projectiles and how they move and act..
Adds 189 biomes, 10 structures, 1 advancement and 10 loot tables.
Counted from the names and data files in the mod, so the list may not be complete.
Replaces 73 of vanilla Minecraft's world generation files and 3 tags.

Security
No harmful code found
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.
- 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 1 web address. 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.27 latest files: the newest file for each Minecraft version and loader. The answer above is about the 4 for recent versions. 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.
- 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
We read its code without running it: it contacts 2 web addresses 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 all 4 files, for recent Minecraft versions. See each file in Releases
- github.comChecks for a new version of the mod.
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Checks for a new version of 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 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.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.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 found24 of 40 changelogs read
