CubeGram
by Pelimesus
CubeGram is a Fabric chat mod that gives each player a registered account, a friend list and private messages synced through a cloud service, opened from inside the game.
What it does
Players register a unique account the first time they open the game, then add friends by their unique game IDs. The messenger interface opens with the default G key, and controls can be changed in the settings. Private messages and global cloud chat with online CubeGram users run in real time, so a conversation carries on whether the other player is on a server, in single-player or building in creative.
Unread indicators mark a friend who has sent a new message. A single click on a friend's entry ends the connection and erases every stored message with that person from the cloud database. Installation means dropping the mod into the mods folder, and Fabric API is required alongside it. The mod runs on the client only, so servers need nothing installed, and it targets 1.21.1 alone with a 1.0.0 file dated 2026-06-17. It is released under All rights reserved and is not open source.
Key features
Global cloud chat
A shared chat channel lets players talk with other online CubeGram users in real time, no matter which server or world they are in.
ID-based friend system
Friends are added through unique game IDs, so players can connect without sharing usernames or servers.
Unread markers
A marker shows when a friend has sent a message that has not been read yet.
Full removal of a friend
Deleting a friend removes the connection and clears the chat history from the cloud database in one click.

Use cases
Who it’s for: Players who want private messages and a friend list inside Minecraft, without relying on a server's own chat. The mod suits players on the 1.21.1 Fabric setup who accept a cloud account.
