Group Chat

Note: This mod is also available as a plugin for paper on modrinth.

Whisper to your whole crew at once — without everyone else on the server reading along.

Group Chat adds persistent chat groups to your server. Create a group, invite your friends, and message everyone in it with a single command — no more /msg-ing the same three people one at a time, and no more accidentally leaking a private conversation into public chat. Message someone (or a whole group) while they're offline, and they'll get it the moment they log back in.

Available for both Paper and Fabric — same features, same commands, same data format, whichever loader your server runs.

Main menu

Features

Group chat — message every member of a group at once with /gmsg (or the shorter /gm)
Offline mailbox — messages to offline players or offline group members are held and delivered on next join, with an unread count so nothing gets missed
Guaranteed delivery option — /gmoffline drops a copy into every member's mailbox, online or not, for anything you want to be sure isn't lost in chat scrollback
Direct messages — /dm for one-on-one, queued automatically if the recipient's offline
Full group management — create, invite, accept/decline, leave, and owner-only kick
Graphical menu — /groupgui opens a point-and-click interface for creating groups, browsing your groups, inviting or kicking members, and picking who to message, if you'd rather not remember command syntax
Tab-completion everywhere — group names, player names, and pending invites all autocomplete
Zero external dependencies — just the plugin/mod, no other downloads required beyond Fabric API on the Fabric side

Data & privacy

All group and message data is stored locally on your server (plugins/Group Chat/ on Paper, <world>/Group Chat/ on Fabric) as plain JSON — nothing is sent anywhere else.

Group names: 2–24 characters, letters/numbers/underscores, case-insensitive
No permission-node gating yet — any player can use any command
Unread messages don't keep history once read via /unread
