Which Minecraft version and loader it works with
Every world has its own Minecraft version and loader (vanilla, Fabric, Forge or NeoForge).
To play with Krypton, create your world with any of these combos:
| Loader | Newest | Minecraft versions |
|---|---|---|
| Fabric | 26.3 | 26.3, 26.2, 26.1.2 and 34 more (oldest: 1.16.2) |
Does it go on the server or on players' games?
Krypton works on the server, on players' games or both: each side gets its perks and nobody gets locked out for not having it.
| Where | Per Modrinth |
|---|---|
| Server | optional |
| Players | optional |
| What the panel suggests | Server and players |
What other mods it needs
None: its latest version doesn't require any other mods on Modrinth.
How to add Krypton to your server
- Open the panel and create a world with a compatible loader and Minecraft version (Fabric, per the table above), or open one you already have.
- In the world's "Mods" section, search for Krypton in the Modrinth catalog. You'll only see what works with your world.
- Add it with the "Server and players" option, the one the panel suggests for this mod.
- Start or restart the server so it installs.
- Ask your friends to download the .mrpack modpack from the panel again.
