Knight Lib
A library that serves as a bridge between mods.
About this Mod
KnightLib is a multiloader utility library designed to eliminate code duplication and provide clean, easy-to-use implementations of systems that every mod tends to reinvent from scratch. Built on Jared's multiloader template, fully compatible with Forge, NeoForge, and Fabric.

Knight Lib 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 Knight Lib compatible with fabric and forge and neoforge?
Knight Lib officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.21, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Knight Lib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Knight Lib 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.
