About
Genesis helps players compare seeds and prepare terrain before playing by adding a live biome map and chunk pre-generation to the Create New World screen. The map samples the actual world generator, including modded biomes, and builds its surface view in three passes; 16 biome families have distinct fill colors, with individual biome borders shown in a legend. Players can pan, zoom, measure distances, inspect coordinates and biome names under the cursor, and enter a numeric or text seed, generate a random one, or copy and reroll it; the chosen seed is passed back to world creation when they leave the screen. For preparation, players choose a radius and thread count, monitor chunk progress and an estimated completion time, and pause, resume, cancel, or enter the world while generation continues in the background. Pre-generation can also be managed with commands for a chosen dimension or all dimensions, optionally centered on specified coordinates, with controls for pausing, resuming, canceling and checking status. The biome preview is client-side and does not alter world generation, while pre-generation requires Genesis on the server or integrated server; the map also reflects world-generation mods such as Tectonic and TerraBlender and automatically displays GeoGradient’s latitude-based climate bands.

Security
No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Found in 6 libraries it includes. See Privacy
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Fabric 1.20.1 to 1.21.1.
- Uses folders outside the game
- It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for NeoForge 1.20.4 to 1.21.1; Forge 1.20.1 to 1.21.
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.3 latest files: the newest file for each Minecraft version and loader. All 3 are 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.
- Uses folders outside the gameUses the temporary files folder.
- Looked for, not foundWe looked for these in the file and did not find them.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 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 all 3 files, 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.Purpose not known.
- 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 38 changelogs read
