FOUNDRY calculator, factory planner, and item guides

weblayoutlab.com is a free fan tool for the game FOUNDRY. It is a production calculator and layout planner: you set an output target, then see recipes, buildings, belts, and power. It is not an official Channel 3 or Paradox product.

Item guides

Every catalog item has a public guide built from game recipes and official research unlocks, plus player-facing tips. Open a page for the recipe card, Used in list, and Unlock requirements when the research dump names a skill. Full item catalog.

Common questions

Do I need an account?

Not to get started. Open the calculator and plan your layout right away - no sign-up. An account is optional if you want cloud-saved layouts.

Do the numbers match the game?

Calculations use game data files - recipes, machines, modules. After a game patch, updates may take a little time. This is a planning tool - verify critical numbers in your save before you place hundreds of machines.

Is this an official FOUNDRY tool?

No. It is an independent fan project for FOUNDRY - not affiliated with Channel 3 Entertainment, Paradox Interactive, or the game developers.

What does it cost?

The tool is free to use. You can optionally support development. Game data and settings stay in your browser unless you publish a layout link yourself.
