FabricClient-side onlyMIT LicenseOpen source1.21.11 – 26.1.2

What it does

The add-on works with Cactus Mod, a lightweight client-side Fabric mod, and adds a new module category to its interface. Modules in the Moss category cover client-side visuals and quality-of-life changes, such as a brand name changer that customizes the client brand reported to servers, arrow trails and a damage indicator.

Only the client needs it, and it has to sit beside Cactus Mod, Fabric Loader and Fabric API. Builds cover 1.21.11 – 26.1.2, with the latest file 1.2.0 for 26.1.2 released on 2026-04-08. The code is open source under the MIT License, and the source and issue tracker are public.

Key features

  1. Brand name changer

    Replaces the client brand string that a player reports to servers, with a value the player sets.

  2. Arrow trails

    Draws colorful particle effects behind arrows, with full customization of color and appearance.

  3. Damage indicator

    Shows clear visual feedback when the player lands a hit.

  4. Optional cheat modules

    Client-side cheat modules are included as an optional part of the category and can be left disabled.

Questions

Does Moss Addon need Cactus Mod installed?

Yes. The add-on extends Cactus Mod, so Cactus Mod, Fabric Loader and Fabric API must all be installed on the client.

Does the server need Moss Addon?

No. It is installed on the player's side alone, so servers need nothing.

Which game versions does Moss Addon support?

Files exist for 1.21.11, 26.1, 26.1.1 and 26.1.2. The latest Fabric file is 1.2.0 for 26.1.2.
