Why choose Krypton

Built specifically for the
unique mechanics of DonutSMP.

We don't just port features — we optimize them. Every module is a standalone .jar; install one or install all four, they don't depend on each other and they don't share state.

Installation

Four steps. Under sixty seconds.

Drop the .jar, install Fabric, restart the game. That's it. Press RShift in-game to open the Krypton GUI.

  1. // step 01

    Download a module

    Pick the .jar you want from the modules section above. Each one is independent — install one, install all four.

  2. // step 02

    Install Fabric + Fabric API

    Run the Fabric Loader installer for your Minecraft version, then grab the Fabric API .jar from Modrinth. Buttons are right below.

  3. // step 03

    Move both into /mods

    Drop the module's .jar and the Fabric API .jar into .minecraft/mods. Create the folder if it doesn't exist.

  4. // step 04

    Launch Minecraft

    Pick the Fabric profile in your launcher and start the game. Krypton's GUI opens with RShift.
