Cavern Chat
by McShinyShoe
Cavern Chat organizes the Fabric chat window into channels, with filters, indicators and a colour-coded direct message option for players on the TheCavern server.
What it does
Cavern Chat was written as an unofficial companion for the TheCavern Minecraft server and adds channel handling to the chat window. Messages can be sorted into channels, a channel can be shown or hidden, and the active channel is marked on screen so a player always knows where a typed message will go. Several interaction shortcuts control this: a plain click toggles a channel's visibility, a shift-click on a channel button switches the active channel, and a ctrl-click leaves only that channel enabled.
The mod runs on the Fabric loader and needs only the client, so players install it while servers run without it. It requires Cloth Config API and Fabric API, and Mod Menu is optional for opening its settings. Cavern Chat is open source under the MIT License, and its source code is public. Twelve release versions are listed, with the newest Fabric file, 1.5.0+1.21.11, dated 2026-08-09.
Key features
Channel filters
Incoming messages can be filtered by channel, so a player can hide traffic from channels they do not follow.
Channel toggle on click
A single click on a channel button shows or hides that channel without changing the active one.
Active channel indicator
The channel that receives typed messages is marked on screen, and a reply marker shows the person being answered.
Chat game filtering
Messages from ChatGames can be filtered out, and direct messages can be shown in a configurable colour.

Use cases
Who it’s for: Players who join community servers with several chat channels, and server members who want a clearer chat window on the TheCavern server. The mod is client-side, so it does not need to be installed on the server.
