advancedchatfilters-next
by Arematics
AdvancedChatFilters-Next is a continued fork of DarkKronicle's AdvancedChatFilters, letting a client rewrite, recolor, convert or read aloud chat messages through configurable filters.
What it does
Filters match chat text and apply one or more actions to it. Available actions replace part of a message or the whole message, change the color of matched text, rainbow specific words, convert text into a different style, turn numbers into Roman numerals, send a message to the action bar, or narrate the message. Filters are defined by the player and can be shared as files.
The mod runs on the client only, so a server does not need it and players can join servers without installing anything. It is built for Fabric and Quilt and is published for 1.21 and 1.21.8, with the latest files for 1.21.8, released 2025-09-28. The code is licensed under the Mozilla Public License 2.0, and its source code and issue tracker are public.
Script-based filters are restricted in scope and include several safeguards for security and stability, but the author advises against running filters from unknown sources. The mod also includes language proofreading and links to a filter repository, an example filter collection and a wiki for learning how filters are written.

Please submit bugs to the issue tracker. While the scope of these scripts are extremely limited, and several measures are put in place to ensure security and stability, these scripts are still very powerful, and you should never run code that you don't trust
