CustomPrefixGUI

CustomPrefixGUI is a lightweight and modern Paper plugin that allows players to create and apply custom gradient prefixes directly in-game through an intuitive GUI.

With a simple /customprefix command, players can open a clean two-step menu where they can enter a custom prefix (up to 12 characters) and choose from 20 built-in gradient styles. A live preview is shown inside the GUI, so players can see exactly how their prefix will look before saving it.

Once applied, the prefix appears in bold with a smooth gradient effect in chat and player display names, giving your server a stylish and polished look without any complex setup.
