About this Mod

Headline

This mod is a library mod for a couple of Globox_Z's mods.
One main feature it adds is the tab registry for visible screen tabs.
Honestly, I never wanted to create a library mod and publish it here like others did but after modding for quite some time now, this makes sense.

This mod is developed for Fabric.
There are no plans to develop a Forge version.

Modpack Permission:
Feel free to use it in any modpacks.

Bug Report:
Just report bugs at the github page.

Frequently Asked Questions

LibZ server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is LibZ compatible with fabric?

LibZ officially supports fabric for Minecraft 1.21.1, 1.21, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with LibZ – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if LibZ consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
