Twitch notes

Twitch support requires user-provided Twitch account settings.

The mod does not include Twitch OAuth tokens, API keys, OpenAI keys, Gemini keys, Google keys, or DeepL keys.

Twitch messages are only sent after explicit user action.

7TV emotes are rendered inside the Minecraft HUD. On the Twitch website, third-party emotes may appear as plain text unless the viewer uses a compatible browser extension.

Why download it?

Custom Chat is useful for players who want a more modern and organized chat interface without changing how normal chat and commands work on servers.

It adds a cleaner layout, quick access to recent messages, readable local logs, clickable message support, translation tools, Twitch chat viewing, 7TV rendering, and quality-of-life improvements for everyday use.

Additional information

Custom Chat is a client-side Fabric mod focused on improving the Minecraft chat interface.

It changes the local chat screen, adds local history, readable logs, click/hover compatibility, optional rank tooltips, translation tools, Twitch HUD integration, and 7TV rendering while keeping normal message and command sending compatible with vanilla gameplay.

The mod does not require installation on the server.

Fair Play / Anti-cheat note

Custom Chat does not modify movement, combat, hitboxes, inventory, world interaction, or server-side checks.

It does not provide X-Ray, ESP, macros, automation, or any gameplay advantage.

The mod is intended only for visual chat improvements, local chat history, local logs, Twitch chat viewing, translation tools, and chat quality-of-life features.
