FastWorkbench

Every crafting operation caches the most recent recipe. The mod then re-checks the recipe only when an item in the crafting matrix itself changes, not when a stack size changes as in vanilla, so the number of matching passes drops to one rather than ranging from one to nearly 600. The mod also addresses a freeze that appears when shift-clicking a full stack, a problem present in later releases of the game.

The mod hides the recipe book button by default in versions where recipes sync anyway, and the button can be turned back on in the configuration. The changes apply through Mixin to the 2x2 player grid and the 3x3 workbench container, so other mods that use the workbench container also get the gains.

Placebo is required on both Forge and NeoForge. The mod is open source under the MIT License and is published for 1.20.1, 1.21.1 and 26.1.2, with Forge builds at 8.0.4 for 1.20.1 and NeoForge builds at 1.21.1-9.1.3 for 1.21.1. The server and every player need the mod installed.
