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 OptiGUI, create your world with any of these combos:

Loaders and Minecraft versions you can play OptiGUI
Loader	Newest	Minecraft versions
Fabric	26.3	26.3, 26.2, 26.1.2 and 29 more (oldest: 1.18)

Does it go on the server or on players' games?

OptiGUI is a client-only mod: it doesn't run on the server. Each player installs it in their own Minecraft if they want it. Add it in the panel as "Players only" and it ships inside everyone's modpack.

What other mods it needs

The latest version of OptiGUI (Fabric) needs these mods. No need to hunt them down: the panel adds them for you.

How to add OptiGUI 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 OptiGUI in the Modrinth catalog. You'll only see what works with your world.
Add it with the "Players only" option, the one the panel suggests for this mod.
Start or restart the server so it installs along with its dependencies.
Ask your friends to download the .mrpack modpack from the panel again.

Frequently asked questions

Which loader and Minecraft version does OptiGUI work with?

OptiGUI has versions for Fabric: 1.18 to 26.3 (32 versions). You pick the loader and version when you create your world; the newest option is Fabric on Minecraft 26.3. The panel's catalog only shows OptiGUI if it has a version for your world.

Do players have to install OptiGUI?

What other mods does OptiGUI need?

Its latest version (Fabric) requires Fabric API and Fabric Language Kotlin. No need to hunt them down: the panel installs them automatically when you add OptiGUI, in the version that matches your world.

Is it worth adding OptiGUI to the server if it's client-only?

Yes, as a convenience. It does nothing on the server, but if you add it as "Players only", it ships inside the .mrpack modpack and everyone gets it without searching. It uses no server resources.
