1.1.0

2 October 2026

New

• The search box knows the abbreviations players type: GC, RC, BC, PU, LDS, RF, UG, prod3 and more. "gc 60" asks for 60 green circuits a minute.
• Plan by machine count: "yellow science 7 machines" plans for seven machines instead of a rate.
• The landing screen shows screenshots of real plans behind the search box.

Fixed

• Machine counts no longer go negative with lots of productivity modules. Speed now stops at −80%, as it does in the game; eight productivity modules in a cryogenic plant used to show a negative count.
• Icons no longer show slices of their neighbours at some sizes.
• The search results list draws over the landing screen text again instead of behind it.

1.0.0

2 October 2026

First public release at factoriocalculator.app.

• Factorio 2.0 and Space Age: pick an item and a rate and see every machine, belt and raw input.
• A table of everything the build needs, grouped into what you build here, what you bring in and what you mine or pipe in. Click a row for its ingredients, where it goes, its recipes and exact machine counts.
• A flow graph of the same plan. Hover a line for its belts and how many machines on each side it feeds.
• Plans only with machines you can build on the chosen planet, and lets you pin a recipe to a machine by hand.
• Belt counts as fractions ("1/3 belt"), and a colour-blind mode that writes the colour on belt and inserter icons.
• Kirk McDonald calculator links open here with the same plan.
