Just SYBAU

Just SYBAU is a client-side Fabric mod that gives you full control over which chat messages you see in Minecraft.

You can hide specific categories of chat instantly, open a clean vanilla-style menu, assign your own shortcuts, clear chat with a custom key, and review hidden messages in a built-in archive.

No server install is required.

Notes

• This mod only changes what you see.
• It does not block, edit, or modify server messages.
• It does not require the server to have the mod.

Troubleshooting

The menu does not open

• Confirm you are using /justsybau (with slash).
• Make sure the correct jar is in the mods folder.
• Confirm game version and Fabric API match the requirements.

Filters seem not to work

• Check each category button state (OFF = filtered).
• Some custom server/plugin formats may not match perfectly.
• If needed, open an issue with logs and an example message format.

Game crashes or UI conflicts

• Update Fabric Loader and Fabric API.
• Test with only Fabric API + Just SYBAU to confirm conflict source.
