    About

    CozyStudios Core is the shared framework behind CozyStudios projects and modpacks, adding configurable, vanilla-friendly content and quality-of-life systems for solo worlds and servers. Its tameable Fernlings can occasionally bonemeal nearby ground, while Mushlings follow their owners and light the way at night; both can be bred with Cozy Crumbs and come in biome-themed variants. Mystical Elk from Dark Forests are rideable mounts with randomized speed and jump stats, and can be bred with Mystical Berries. The mod adds an Arborist villager who sells saplings and may offer Cozy Crumbs at higher levels, plus a rare Mystical Trader who sells Cozy Crumbs and Mystical Berries and may carry a Golden Leaf. Tranquil Lanterns repel mobs and prevent spawning in a configurable radius, which players can view in-world; the Golden Leaf used to craft one also grants regeneration while carried and can be eaten for a Golden Apple effect. Building and utility additions include a Kiln that smelts blocks such as stone, bricks, terracotta, and clay twice as fast, can dry wet concrete, and accepts custom recipes, as well as an Arborist Table for assigning the Arborist profession. Other additions include a Jungle Horn found in Jungle Temples, Cozy Crumbs for taming Fernlings and Mushlings, Mystical Berries for taming Elk, and original music discs including “AT Original Soundtrack Music Disc” and “Dayspring.” Configurable quality-of-life features let players recolor beds, wool, and banners with dye, expand Mason trades with building materials such as packed mud, bricks, tuff, terracotta, and calcite, and adjust stack sizes for items normally limited to 16. The mod also adds recipes for items such as saddles, name tags, and horse armor, and makes hunger function in Peaceful mode, with these systems configurable.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Changes your mods folder
    It can add or replace files in your mods folder, for example to update itself.
    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Found: your user folder and your Downloads.
    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 · The latest file checked, last on 21 Oct 2026
    • 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.
      1 latest file, 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 game
      Uses Downloads.
    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, other programs, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    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 · Its one file read
    • 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
    • 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, sounds 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.
