JLM
by Komti23
JLM lets server owners set custom join and leave messages for players, with the player's name substituted into each one.
What it does
Messages are edited in a configuration file, so text can change without touching code. Placeholders such as the player's name are replaced with the real nickname when a player enters or exits. Color codes are supported, which lets the chat greeting stand out. Configuration reloads can be triggered with a command, so changes apply without restarting the server.
The mod is a Forge build and is also available for Paper, Spigot, Bukkit and Purpur. Files cover 1.18 – 1.21.6 across 22 release versions, with the newest Forge file for 1.20.6. The mod is released under All rights reserved and is not open source, though public source code links exist. Published first on 2025-03-01 and last updated 2025-08-28.
Key features
Custom join and leave messages

Player name substitution
A placeholder inside a message is replaced by the nickname of the player it concerns.
Color codes in messages

Reload without restart

How it compares
Auto Restart is server-side only, published for Forge and NeoForge across 1.17.1 – 26.3, and is not open source. Chat Config is a Forge mod for 1.19.4 that runs on both client and server, and it is not open source. Exit Protection covers Fabric, Forge and NeoForge for 1.20.1 – 1.21.1 and runs client-side only, so it does not change server behavior.
