About this Mod
Slowcraft
Slowcraft is a library mod for modpack, datapack and mod authors to create progressive crafting items called SlowTools.
Inspired by the Knitting system in Better Than Wolves and the Polishing system in Create.

SlowTools
SlowTools are intermediary crafting items, intended to be time-consuming crafts. The player holds right-click to work on it while its durability bar shows the current progress.
Progress is saved when the player stops, so a long craft can be completed a little at a time. Once the bar finishes, the SlowTool is consumed and its outputs are given to the player.
A real life example could include things like knitting, weaving, or whittling.

Requirements
- Fabric API
- (Optional) JEI
Slowcraft is a library mod. Installing it by itself does not add anything; mods, modpacks, and datapacks use it to create their own SlowTools.
Documentation
Made for Modpacks, Datapacks and Mods
Slowcraft supports two ways to create SlowTools:
- Data-driven: SlowTools can be added through datapack JSON files without any Java.
- Java-driven: SlowTools can be registered as items for mod developers who want custom sounds, assets, or additional behavior.
SlowTools can be configured with a crafting time, up to four item outputs, and more!
Integration
When JEI is installed, Slowcraft adds a Progressive Crafting recipe category showing each SlowTool's outputs and crafting time.
SlowTools have an Information page, and SlowTools are added to JEI automatically.

JEI is optional and is not required to use Slowcraft.
Planned Integration:
- EMI / REI / etc.
- KubeJS

Slowcraft was originally created for a modpack of my own, but anyone is welcome to use it in their mods or modpacks.

Slowcraft 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 (26.2). You can switch loaders with one click in the panel.

Server lagging with Slowcraft – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Slowcraft consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
