About this project

What does Cubium add?

🌐 Cubium – The In-Game Minecraft Browser

Cubium is a client-side Minecraft mod that integrates a Chromium-based browser directly into the game. With Cubium, you can browse the web seamlessly without ever needing to tab out. The browser can be opened at any time using the B key (default, customizable in settings).

🔄 Newer Versions

The Cubium Mod is no longer updated regularly on CurseForge. Please use Modrinth to get the latest versions.

🚨 Important

Cubium uses the MCEF library. Make sure to install it together with the mod.

You will also need the Fabric API and the Fabric Language Kotlin for the mod to work.

If you want to use Quilt, you'll need to use the Quilted Fabric API instead of the Fabric API, and the Quilt Kotlin Libraries instead of the Fabric Language Kotlin.

🧩 Works Great with TMYK

Cubium works seamlessly with the TMYK mod by fingerguns83. TMYK allows you to easily access wiki links by typing /wiki [search term], or simply /wiki to look up information about blocks, entities, or fluids you're currently looking at.
