About this Mod
CrafterLib
A robust Custom Crafter library for Minecraft
💡 Notice: A tool to generate recipes from a GUI is coming soon!
CrafterLib provides a custom crafting table that allows recipes with items that have components to be both input and output. It strives for simplicity and performance, whilst maintaining usability.
It currently only supports Shaped "Exactly Where Placed" recipes, though it has partial support for Shapeless (only works if a recipe does not require multiple of the same item).

CrafterLib server crashes on startup – what to do?

CrafterLib officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.6, 1.21.5. 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 CrafterLib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if CrafterLib consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
