chat isolation
by puppykairu
Chat Isolation is a client-side Fabric mod that filters out server and system chat so players can keep their focus during tight PvP fights.
What it does
Chat Isolation blocks most server and system messages from appearing in chat, which keeps the screen clear in competitive fights where focus matters. Messages still come through when they concern a player on the whitelist, such as a rekit, regear or heal, so critical events stay visible without the unrelated chatter from spectators or other players.
The filter runs on the client only, so a server does not need to install anything for it to work. Its settings, including the whitelisted opponents, are saved automatically and loaded again the next time the game starts. The mod is published for Fabric with a single file for 1.21.11, released on 2026-06-10 under the MIT License, and it is not open source.
Key features
Opponent whitelisting
Players added to the whitelist are the only names whose messages pass the filter, so chat about the chosen opponent stays readable.
Smart system broadcast filtering
Server and system messages are hidden unless they explicitly reference a whitelisted opponent, keeping the chat log short.
Critical event alerts
Messages about rekitting, regearing and healing are kept when they involve a whitelisted player, so key moments are not lost.
Persistent configuration
The whitelist and other preferences are saved automatically and restored on each launch, so setup is needed only once.

Use cases
Who it’s for: Players who take part in competitive PvP fights and want less chat clutter during a match. It suits clients on any Fabric setup for 1.21.11, and it changes nothing on the server side.
How it compares
Player Chat Filter is also a client-side Fabric mod under the MIT License, published for 1.21.11, and it is open source. Chat Focus covers 1.21 – 1.21.11 with a client-side environment and the MIT License, but it is not open source. Multiplayer Isolation is open source under the MIT License, but it is server-side only and targets 1.21.1 – 1.21.5, so it works on the server rather than in the player's client.
