What the planner does
The planner solves a whole production line in one pass instead of walking recipe by recipe. Give it a target — 60 Iron Plate per minute, a fixed amount of power from Fuel generators, or as much of an item as your resource limits allow — and it returns the recipes to run, how many machines of each, the clock speeds, the power draw, and the ore and fluids the line consumes at the map end.
It is meant for the point where a factory stops fitting in your head: when an alternate recipe changes the whole ingredient mix, when a byproduct has to go somewhere before it backs up a pipe, or when you want to know whether the nodes you have secured can really feed the build you are drawing. Everything is recalculated the moment you change a target, so it is quick to try the version you were not sure about.
What it gives you
- Optimal recipe selection with a linear programming solver, weighted toward raw resources, power or building count
- A flow chart of the whole line, from raw resources through to the finished item
- Excel export with the summary, building list, item balance, resources, construction cost and logistics on separate sheets
- Power planning that solves generators, fuels and byproducts together with production
- Loop templates such as complete oil recycling and byproduct water reuse
- A build list in build order, with machine counts per step and the belt or pipe tier each flow needs
- A recipe reference for every item: how it is made, what uses it, rates per minute and output per MW
- Twelve interface languages
Where the numbers come from
Recipes, buildings, power figures and sink points are taken from the official game data (version 1.1.x), and item and recipe names use the official in-game English names, so the wording matches what you see on screen.
Your plans stay with you: they are solved in your browser and saved there, never uploaded. A finished plan can be packed into a share URL, which reopens the same conditions on another device or for someone else.
Frequently asked questions
Is the planner free, and do I need an account or an install?
It is free, there is no account to create and nothing to install. Open the page, name the item you want and the rate you want it at, and the plan appears. The game data ships with the page and the solving happens in your browser, so edits do not wait on a server.
Which game version is the data from, and where do the numbers come from?
Recipes, buildings and power figures are read from the game's own data files for version 1.1.x: 198 items, 291 recipes and 23 buildings. Nothing is retyped by hand, and item and recipe names use the official in-game translations, so the wording matches your screen.
Does it handle alternate recipes, Somersloops and overclocking?
All 109 alternate recipes can be switched on and off individually, and the solver only uses the ones you enable. Enter your Somersloop count and it adds fully amplified variants of the supported recipes, worth 2× the output for 4× the power. Production clock can be capped from 10% to 250%, extraction at 100% / 150% / 200% / 250%.
Can it plan power generation together with production?
Power is solved together with production. Allow the Coal-Powered Generator, Fuel-Powered Generator or Nuclear Power Plant, pick their fuels, then set a "Generation target" or tick "Cover factory power consumption". Fuel production is planned too, and byproducts such as Uranium Waste appear in the balance. Generator clock speed is fixed at 100%. Generator overclocking is not supported.
Can I get the result into a spreadsheet?
The Excel export writes an .xlsx with 6 sheets: Summary, Building List, Item Balance, Resources, Build Cost, Logistics. The file is built in your browser and downloaded straight away. On screen the same plan is also available as a flow chart and as a "Build list" that runs in build order, starting from extraction.
Where are my plans stored, and can I share them?
Plans are solved in your browser and saved there as well, in IndexedDB; the plan data is not sent to this site. Sharing packs the whole plan into the URL, so opening the link reproduces the same conditions on another device or for a friend. Clearing site data removes the saved plans.
What languages is the planner available in?
The interface is available in 12 languages. It follows your browser setting at first and can be switched inside the app. Item, recipe and building names come from the game's own translation for each language. The item reference and the written guides on this site are published in Japanese and English.
