StreamerUtils
by Codex_bat
With StreamerUtils installed on a server, viewers of a streamer can trigger in-game effects through Twitch chat.
What it does
Viewers can type chat commands such as highlight to make a player glow, or firework to launch a rocket with a sound cue. A new subscriber-style event can also set off an alert on the server. Servers that want a streamer-friendly setup can use the mod to give viewers a more interactive experience without changing anything on their own machines.
Players join without installing anything, since the environment is server-side only. A companion resource pack makes the custom nametag icons visible to players who do not run any client mods. The mod packages Twitch4J internally, which accounts for most of its size of around 17k KB, but Fabric API and Twitch4J are still listed as required dependencies. The source is available on GitHub, so server owners can check the code before installing it.
Installation requires Fabric API. The file for 1.21.11 is 3.0.0-1.21.11, published on 2026-08-28, and the mod has been on the catalog since 2026-04-21. Support is built for Minecraft 1.21.11, and other builds may work once their mappings are updated. Additional versions may be added on request in later updates.
