Chat Suffix
by qiann
Chat Suffix is a Forge client mod that appends a custom suffix to the messages a player sends in multiplayer chat.
What it does
When a player sends a chat message, the mod attaches a configured suffix to the end of it before the text leaves the client. The change happens only on the sending side, so the server receives the modified message as ordinary chat and needs nothing extra. The result gives a player's messages a recognizable signature in busy multiplayer servers, where many people type in the same channel. The processing applies to regular chat messages. Lines that begin with a slash are treated as commands and are passed through untouched, so game commands keep working exactly as before.
Settings are stored in a configuration file, and the file is the recommended way to keep the suffix permanent. A graphical settings screen opens with the K key and offers the same options. Changes made in the game interface are saved when the client restarts or the world is exited, so players who want a fixed setup should edit the file directly. Chat Suffix is licensed under the MIT License and is not open source. It is published for Forge only, for 1.18.2 and 1.20.1, and only the client needs it.
Key features
Automatic suffix
A custom suffix is added to every regular chat message without the player typing it each time.
Command passthrough
Messages starting with a slash are left unchanged, so game commands continue to function normally.
File-based settings
Main options are kept in a configuration file that can be edited directly for a lasting setup.
In-game settings screen
A graphical configuration screen, opened with the K key, changes the same settings without editing files.

Use cases
Who it’s for: Players who join multiplayer servers and want their chat messages to carry a consistent custom ending. Only the client installs the mod, so server owners do not need to add anything.
How it compares
Hide Chat is a Forge client mod for 1.20 – 1.20.6 under All rights reserved, and it is not open source; Chat Suffix covers 1.18.2 and 1.20.1 under the MIT License. VeridianCopy is a client-side mod for Fabric and Forge across 1.16.4 – 1.20.1 and is open source under the MIT License, so it covers a broader set of loaders where Chat Suffix is Forge-only.
