About

A recipe and technology browser for Pyanodons, the Factorio overhaul by pyanodon and the pY team. Recipe/item/technology data was extracted directly from the mod and reflects mod version (Pyanodons on Factorio 2.1.17, extracted 2026-09-13). This site may or may not be current or on the same version as your playthrough; sorry! (Good alternatives are the Factorio 2.0+ in-game item browser or the in-game mods FNEI or Recipe Book.)

Built by Patrick McKenzie (@patio11) · kalzumeus.com · @patio11 on X, with coding assistance from Claude Code.

Science tiers are derived from the tech tree: a recipe's tier is the earliest science pack that lets you research it. Barrelling and void recipes are omitted. Recipes with no research prerequisite that the mod enables by script, such as upgrade choices, are shown but marked.

Data errors are mine, not the mod's.
