About this Mod
This mod allows you to lock slots meaning that you e.g. cannot use them in hotbar, cannot select them in hotbar, cannot put any items in them, etc. You can do this with commands or other mods can use the (quite horrible) API.
This mod is compatible with modded inventories, unlike other implementations.

Inventory Lock server crashes on startup – what to do?
Most common cause: wrong quilt 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 (1.20.1). You can switch loaders with one click in the panel.
Is Inventory Lock compatible with quilt?
Inventory Lock officially supports quilt for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Inventory Lock – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Inventory Lock 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.
