About this Mod
An API to add inventory tabs.
Natively for 1.20.1 but should work on every version.
Made for SkillZ and based on Globox_Z's LibZ I stripped out the other code and added sidebar functionality.
Disabling Tabs
If a tab has its ID set, you can find it under config/tabapi_tabs.json. true for enabled, false for disabled.

InventoryTab@Nullable Identifier id: The id of the tab.

TabAPI 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 (1.20.6). You can switch loaders with one click in the panel.
Is TabAPI compatible with fabric?
TabAPI officially supports fabric for Minecraft 1.20.6, 1.20.5, 1.20.4. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with TabAPI – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if TabAPI 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.
