Sources & artwork credits

Production recipes and inventory icons come from the FactorioLab full-Pyanodon dataset. Research requirements use the official Pyanodon cached research data. The interactive guide's Sources & versions panel lists the dataset versions.

Building previews are static frames assembled from installed game and mod graphics. Their versions may differ from the recipe dataset. See the image credits and building artwork provenance for sources, versions and extraction details.

Accuracy & use

Mod updates, startup settings and optional mods can change recipes and research. Check your in-game recipe information when planning a factory. The batch planner does not simulate operating fuel, modules, productivity or steady-state recycling.
