NoLogMessage
by Fozeton
NoLogMessage stops Minecraft from writing in-game chat messages to the local latest.log file, and the chat on screen stays as normal.
What it does
The mod intercepts chat output on the client before the game passes those lines to its logger. Chat text therefore never reaches latest.log or any other saved log file on the local disk, while messages still appear normally during play. Players whose logs fill up with repeated lines from busy multiplayer servers, mini-game lobbies or automated bots can keep those files compact.
NoLogMessage is client-side only, so only the player's own computer needs it and the server runs without it. It requires Fabric API, and files are published for Fabric alone, for 1.21.4. The code is open source under the GNU General Public License v3.0 only. The mod does not change the game's performance, since it is built on Mixins and has a very small footprint.
The protection covers only the local computer. Server administrators still log the chat that reaches their own servers, so the mod does not stop them from keeping records. Its purpose is the player's own files, for example when a log is shared with an admin for troubleshooting without exposing private conversations.

How it compares
MChat Fix and Better No Chat both run on the client only and are for Fabric 1.21.11, under All rights reserved, so they are not open source. Moderation Log is also client-side only for 1.21.11, under the MIT License, but it is not open source. World File Cleaner targets 1.21.11 on the server side and is open source under the MIT License. NoLogMessage is the 1.21.4 version, and it is open source under the GNU General Public License v3.0 only.

What the author says
A simple, lightweight client-side mod that completely stops Minecraft from saving chat and game messages to your local log files (latest.log). NoLogMessage intercepts this process on the client side. It prevents the game from sending these chat lines to the logger, meaning your in-game chat text never gets recorded…
