Slowcraft

SlowTools are intermediary crafting items for time-consuming crafts, modeled on real-life work such as knitting, weaving and whittling. A player holds right-click to work on one, and a durability bar shows the current progress. When the progress bar reaches its end, the SlowTool is used up and the player receives what it produced. Progress is saved, so a player who stops a long craft can return to it later.

SlowTools can be defined through datapack JSON files without writing Java. A SlowTool is configured with its crafting time and up to four item outputs. Mod developers who want registered items with custom sounds, assets or additional behavior can use the Java route, and the Example Datapack shows the format. Mods, modpacks and datapacks can use Slowcraft to create their own SlowTools.

Slowcraft is published for Fabric only, for game versions 1.21.1, 26.1.2 and 26.2, and the latest file is 0.6.1 for 26.2. Installing it does not add any items or blocks by itself. It is server-side only, so players join without installing it, and the code is open source under the MIT License. With JEI present, Slowcraft gains a Progressive Crafting category in its recipe viewer, listing each SlowTool's results and steps, though JEI itself is not mandatory.
